Description

  The present invention relates to a wearable portable display device, a head-mounted display device, a display processing system, a program, and the like.

  In recent years, users (users) of miniblogs are rapidly increasing. And these miniblog users are increasingly reading text posted on miniblogs from portable information terminal devices. Compared to the display unit (display) of desktop PCs (Personal Computers) and notebook PCs, the display units of portable information terminal devices are mostly small in display area, so that characters can be easily read by the user. It is desirable to display.

  Further, it has been devised to use an HMD (Head Mounted Display) as a portable information terminal device. Even when a sentence or the like is displayed on the HMD, it is desirable to perform display control so that the user can easily read. For example, in Patent Document 1, as one of such display controls, a display position having an MTF (Modulation Transfer Function) characteristic that satisfies a predetermined condition is evaluated, and a display that determines a character position and a character size that are easy for a user to read is determined. An invention for performing control is disclosed.

JP 2007-142542 A

  In order for the user to reliably identify the text data displayed on the HMD, the high visibility of the characters is important. Further, in an HMD having a relatively small display area, a device for efficiently using the display area is required. Therefore, when an HMD is used as a display device, it is conceivable to perform display control as disclosed in Patent Document 1 described above.

  However, it is considered that the HMD that superimposes the external field of view and characters and displays them on the display unit is often used, for example, when the user is in the city or when the user is moving. For this reason, the user needs to pay attention not only to the displayed text data but also to the outside world, and cannot keep the awareness on the text data indefinitely.

  Therefore, it is desirable that the user can grasp the contents of the text data displayed on the display unit at the earliest possible timing. Even if the text data is long and the contents of the entire text data cannot be grasped immediately, it is only necessary to determine whether the user should read the information at the earliest possible timing.

  According to some aspects of the present invention, the wearable portable display device and the head-mounted display device can determine whether or not the user should read the text data displayed on the display unit at an earlier timing. A display processing system, a program, and the like can be provided.

  One aspect of the present invention includes a display unit that displays text data, a display attribute change processing unit that performs a display attribute change process on some characters or words of the text data, and the partial characters or words The present invention relates to a wearable portable display device including a display control unit that performs control to display the text data whose display attribute has been changed on the display unit.

  In one aspect of the present invention, the display attribute change processing unit changes the display attributes of some characters or words of the sentence data, and the display control unit changes the display attributes of some characters or words. Is displayed on the display.

  As a result, the user can more easily identify some characters or words of the text data whose display attributes have been changed.

  Also, in one aspect of the present invention, the display attribute change processing unit performs a font size change process for a predetermined number of characters or words from the beginning of the sentence data, which are some characters or words of the sentence data. May be.

  As a result, the user can determine whether or not to read the text data displayed on the display unit at an earlier timing.

  In one aspect of the present invention, the display attribute change processing unit sets a first character or a first word in the sentence data as a first display attribute, and the first attribute in the sentence data. Even if the second attribute different from the first character or the second word different from the first word is set to the second display attribute different from the first display attribute, the display attribute changing process is performed. Good.

  This makes it possible to change display attributes of at least two characters in the text data.

  In the aspect of the invention, the display attribute change processing unit may perform a font size change process on one character of the sentence data.

  As a result, for example, it is possible to change the display attribute of one character that expresses the content of the sentence data in the sentence data.

  In one aspect of the present invention, the display attribute change processing unit sets the first character or the first word in the sentence data to a first font size, and the first attribute in the sentence data. The display attribute changing process for setting a second character after the first character or a second word after the first word to a second font size smaller than the first font size. You may go.

  As a result, it is possible to make it easier for the user to guess the content of the entire sentence, to determine whether the information should be read immediately, or the like at an earlier timing.

  In the aspect of the invention, the display attribute change processing unit may perform the display attribute change process such that the font size decreases as the sentence data moves from the beginning to the end of the sentence.

  As a result, it is possible to keep the user's attention away from the characters displayed on the display unit.

  In the aspect of the invention, the display attribute change processing unit may display the character or the word displayed when the display control unit displays the character or the word included in the text data on the display unit. When the display control unit displays the specific punctuation included in the text data on the display unit, the display attribute of the display attribute is displayed for the specific punctuation displayed. The change process may not be performed.

  As a result, it is possible to display a specific punctuation that rarely expresses the meaning of the entire sentence without emphasizing it, and it is possible to display characters or words that express the meaning of the entire sentence in a relatively emphasized manner. Become.

  Moreover, in one aspect of the present invention, an information acquisition unit that acquires attribute setting information of characters or words of the sentence data from outside a wearable portable display device, the display attribute change processing unit includes the acquired attribute Based on the setting information, the display attribute changing process may be performed on the characters or words of the sentence data.

  Thereby, it becomes possible to change the display attribute of the character or word of sentence data by the attribute setting information to be used.

  In one aspect of the present invention, the information acquisition unit includes an attribute setting information storage unit that stores the attribute setting information acquired by the information acquisition unit, and the information acquisition unit stores the attribute setting information associated with the sentence data. An identifier may be acquired, and the display attribute change processing unit may perform the display attribute changing process on the text data based on the attribute setting information associated with the acquired identifier.

  Thereby, it is not necessary to acquire attribute setting information every time the text data is displayed, and it becomes possible to reduce the amount of communication between the wearable portable display device and the external device.

  In one aspect of the present invention, an attribute setting information storage unit stores first attribute setting information of characters or words of the sentence data and second attribute setting information different from the first attribute setting information. The display attribute change processing unit performs the display attribute change processing on the text data based on the first attribute setting information until a predetermined timing, and after the predetermined timing, The display attribute changing process may be performed on the sentence data based on the attribute setting information.

  This makes it possible to change display attributes for the same character as time elapses.

  Moreover, in one aspect of the present invention, a partial area that is smaller than the display area of the display unit and that sets a partial area associated with character or word attribute setting information of the sentence data as the display area The display attribute change processing unit may include a setting unit, and the display attribute change processing unit may perform the display attribute change process on the text data based on the attribute setting information associated with the partial area.

  Thereby, for example, when the display position of the character of the text data is a predetermined position in a partial area, the display attribute of the character is changed based on the attribute setting information associated with the partial area. Is possible.

  In one aspect of the present invention, a motion sensor signal acquisition unit that acquires a motion sensor signal representing a motion of the user's body from the motion sensor is included, and the partial region setting unit is based on the acquired motion sensor signal. At least one of the position and size of the partial area in the display area may be set.

  Thereby, the user can designate a character whose display attribute is to be changed or a partial area of the display area by moving the head.

  Moreover, in one aspect of the present invention, the display attribute change processing unit uses the attribute setting information associated with the partial area until a given timing to change the display attribute for the sentence data. After the given timing, the change processing of the display attribute may not be performed on the sentence data using the attribute setting information associated with the partial area.

  As a result, it is possible to cancel the highlighted character display without changing the character display attribute after a predetermined timing.

  In one aspect of the present invention, the display attribute change processing unit sets a determination region for a character or word displayed in the display region, and an overlap region is provided between the determination region and the partial region. If it is determined whether or not the overlap area exists, the change of the display attribute based on the attribute setting information associated with the partial area determined to overlap with the determination area Processing may be performed, and the display control unit may display characters or words corresponding to the determination area on the display unit.

  As a result, it is possible to determine which partial region to use attribute setting information associated with which character or which word is used in a similar manner while reducing the processing amount.

  In the aspect of the invention, the display attribute change processing unit causes the display unit to scroll-display characters or words included in the sentence data, and the determination set for the scroll-displayed characters or words is performed. The display attribute changing process based on the attribute setting information associated with the partial area determined to overlap with the determination area when it is determined that the overlapping area exists between the area and the partial area May be performed.

  As a result, it is possible to change the display attribute by determining whether or not there is an overlapping area even for text data that cannot be displayed in the display area at a time.

  In one aspect of the present invention, the display attribute change processing unit associates the first partial area associated with the first attribute setting information of the character or word with the second attribute setting information of the character or word. When the determined second partial area is set as the display area, the determination area overlaps with the first partial area and does not overlap with the second partial area. When the display attribute is changed for the sentence data based on the first attribute setting information, and the determination area overlaps with the first partial area and also overlaps with the second partial area May perform the display attribute changing process on the text data based on the second attribute setting information.

  As a result, when a partial area and a judgment area are newly overlapped by scrolling, it is possible to change display attributes using attribute setting information associated with the newly overlapped partial area. become.

  In one aspect of the present invention, the display attribute change processing unit associates the first partial area associated with the first attribute setting information of the character or word with the second attribute setting information of the character or word. When the second partial area is set as the display area, the first overlapping area where the determination area and the first partial area overlap is the determination area and the second part. If it is determined that the area is larger than the second overlapping area, the display attribute is changed for the sentence data based on the first attribute setting information, and the second overlapping area May be larger than the first overlapping area, the display attribute changing process may be performed on the text data based on the second attribute setting information.

  This makes it possible to change display attributes using attribute setting information associated with a partial area having a larger overlap area with the determination area.

  In one aspect of the present invention, the display attribute change processing unit increases the font size of the character or word included in the sentence data based on the attribute setting information. Alternatively, the determination area corresponding to the word may be enlarged, and it may be determined whether or not an overlapping area exists between the enlarged determination area and the partial area.

  Thereby, it becomes possible to make the timing which changes the display attribute of a character or a word correspond with the timing estimated from the appearance of the displayed character.

  Moreover, in one aspect of the present invention, the display attribute change processing unit has the display attribute of the text attribute based on the attribute setting information indicating a font size, a character color, a character thickness, or a font type. Change processing may be performed.

  This makes it possible to change the font size, character color, character thickness, or font type of the text data.

  In one aspect of the present invention, the display control unit displays characters or words included in the sentence data on the display unit without scrolling until a predetermined timing, and the sentence data is displayed after the predetermined timing. You may start scroll display of the character or word contained in.

  Thereby, for example, it is possible to display a sentence head portion of sentence data for a long time.

  In the aspect of the invention, the display unit may display the text data so as to be superimposed on an external field of view.

  As a result, the user can quickly switch an object to be watched carefully between the text data and the outside world.

  Another embodiment of the present invention relates to a head-mounted display device that is a head-mounted wearable portable display device.

  In another aspect of the present invention, the wearable portable display device includes: a wearable portable display device; and a terminal device that is communicatively connected to the wearable portable display device, wherein the wearable portable display device displays first sentence data. 1 display unit, a display attribute change processing unit that performs a display attribute change process on some characters or words of the first sentence data, and the first sentence data is displayed on the first display unit. A second display unit that displays second text data; and a second display unit that displays the second text data on the second display unit. The wearable portable display device or the terminal device includes a user operation information acquisition unit that acquires operation information input by a user, and the first display control unit includes: Before some of the letters or words Control is performed to display the first sentence data whose display attribute is changed on the first display unit, and the second display control unit is configured to display the first sentence displayed on the first display unit. Control that displays the second text data on the second display section when the user operation information acquisition section acquires the operation information representing the display instruction of the second text data associated with data. Related to the display processing system.

  Thereby, for example, it is possible to display second text data representing more detailed information about the contents of the first text data on the second display unit of the terminal device.

  Another aspect of the present invention relates to a program that causes a wearable portable display device to function as each of the above-described units.

  Hereinafter, the first to third embodiments will be described. First, the background of each embodiment and the outline of the method will be described together. Next, a system configuration example, method, and processing flow will be described in detail for each embodiment. In addition, each embodiment described below does not unduly limit the content of the present invention described in the claims. In addition, all the configurations described in the embodiments are not necessarily essential configuration requirements of the invention.

1. Overview In recent years, the number of users (users) of miniblogs has increased rapidly. And these miniblog users are increasingly reading text posted on miniblogs from portable information terminal devices. Compared to the display unit (display) of desktop PCs (Personal Computers) and notebook PCs, the display units of portable information terminal devices are mostly small in display area, so that characters can be easily read by the user. It is desirable to display.

  Further, it has been devised to use an HMD (Head Mounted Display) as a portable information terminal device. Even when a sentence or the like is displayed on the HMD, it is desirable to perform display control so that the user can easily read. For example, text data can be displayed so that the user can read more easily by improving the visibility of characters or using the display area efficiently.

  Specifically, in the invention disclosed in Patent Document 1 described above, as one of such display controls, a display position having an MTF (Modulation Transfer Function) characteristic that satisfies a predetermined condition is evaluated and read by the user. Display control to determine easy character position and character size.

  Here, it is considered that an HMD that displays an external field of view and characters superimposed on the display unit is often used, for example, when the user is in the city or when the user is moving. Unlike a handheld information terminal device such as a smartphone, an HMD that superimposes an external field of view and characters and displays it on a display unit does not require a user to move his / her line of sight when reading text data. Therefore, even when reading the text data, it is convenient because it is possible to quickly turn the attention forward by moving only the line of sight without changing the orientation of the head.

  However, even if the characters are displayed in the same direction as the external field of view, when the user actually reads the text data, the consciousness concentrates on the displayed characters and the attention to the outside world is distracted. There are many cases. That is, even when using an HMD that superimposes the external field of view and characters and displays them on the display unit, it is difficult to see the text data and the external world at the same time, and the user is conscious of the displayed text data and the external world separately. It is necessary to turn it, and it is impossible to keep consciousness only on the text data.

  Therefore, for safety, it is desirable that the user can grasp the contents of the text data displayed on the display unit at the earliest possible timing. Even if the text data is long and the contents of the entire text data cannot be grasped immediately, it is only necessary to determine whether the user should read the information at the earliest possible timing.

  For example, in the example of the miniblog mentioned above, if the user can quickly determine only the name of the person who posted the text data, the information that should be read immediately or information that can be skipped at an early timing It will be possible to judge. Similarly, when an e-mail is received, it is only necessary to quickly determine only the sender of the e-mail. In addition, for example, when displaying a news article, only the field of the news article can be determined first. If possible, it will be possible to quickly determine whether the information should be read immediately. When the user determines that the information should be read immediately, the user checks the text data by stopping, etc., and if the user determines that the information may be skipped, the user can read the information at an early timing. You will be able to turn your attention forward.

  According to the following first to third embodiments, the wearable portable display device that can determine whether or not the user should read the text data displayed on the display unit at an earlier timing, A head-mounted display device, a display processing system, a program, and the like can be provided.

  Examples of the wearable portable display device include various wearable displays such as a watch type, a pendant type, and a glasses type, a portable music device having a display unit, a voice recording device, and a digital camera. The wearable portable display device may be any device as long as it is a portable device having a display unit. In the following first to third embodiments, a head-mounted display device among the wearable portable display devices will be described as an example.

2. 1. First Embodiment 2.1 System Configuration Example Next, a configuration example of a head-mounted display device 100 of the present embodiment is shown in FIG. The head-mounted display device 100 includes a display unit 110, a display control unit 120, a display attribute change processing unit 190, an information acquisition unit 130, and an attribute setting information storage unit 140. The head-mounted display device 100 is not limited to the configuration shown in FIG. 1, and various modifications such as omitting some of these components or adding other components are possible. is there.

  Next, the connection of each part is demonstrated. The display control unit 120 is connected to the display unit 110. The display attribute change processing unit 190 is connected to the display control unit 120. The information acquisition unit 130 is connected to the display attribute change processing unit 190 and the attribute setting information storage unit 140. The attribute setting information storage unit 140 is connected to the display attribute change processing unit 190. Any one of the terminal device 200, the server device 300, and the storage device 400 is connected to the information acquisition unit 130.

  Next, processing performed in each unit will be described.

  First, the display unit 110 displays text data in accordance with display control of the display control unit 120 described later. The display unit 110 can be realized by, for example, a liquid crystal display, an organic EL display, electronic paper, or the like. The display unit 110 may be a deflection unit such as a half mirror or a projection unit that projects a display image directly to the eyes of the user.

  Next, the display control unit 120 performs control to display text data on the display unit 110.

  And the display attribute change process part 190 performs the display attribute change process etc. about the character contained in text data. The functions of the display attribute change processing unit 190 and the display control unit 120 can be realized by hardware such as various processors (such as a CPU) and ASIC (such as a gate array), a program, and the like.

  Furthermore, the information acquisition unit 130 is connected to at least one of the terminal device 200, the server device 300, and the storage device 400, which will be described later, by wired or wireless communication, and includes attribute setting information and an identifier of the attribute setting information. Etc. The information acquisition unit 130 does not necessarily acquire attribute setting information, an identifier, and the like from any one of the terminal device 200, the server device 300, and the storage device 400. The attribute setting information, the identifier, and the like may be acquired from 300 and two or all three of the storage devices 400, respectively.

  The attribute setting information storage unit 140 stores the acquired attribute setting information. The function of the attribute setting information storage unit 140 can be realized by a memory such as a RAM or an HDD.

  Next, the terminal device 200 is a portable terminal device (electronic device) such as a smartphone or a PDA. In addition, the terminal device 200 may be an electronic device such as a PC (Personal Computer), a digital audio player, a game machine, or a car navigation system. The server device 300 is connected to the information acquisition unit 130 via a network. The storage device 400 indicates an external HDD, a USB memory, or the like.

2.2 Method Next, the method of this embodiment will be described.

  The head-mounted display device 100 of the present embodiment described above includes a display unit 110 that displays text data, a display attribute change processing unit 190 that performs display attribute change processing on some characters or words of the text data, And a display control unit 120 that performs control to display text data in which display attributes of some characters or words are changed on the display unit 110.

  In the following, an example in which the display attribute is changed mainly for characters included in the text data will be described. However, the display attribute can be similarly changed for a word (word) included in the text data. It is also possible to change the display attributes for each idiom, phrase, or search keyword by changing the display attributes of a plurality of words. The same applies to the second and third embodiments described later.

  Here, text data refers to data composed of character information. For example, text data refers to text posted on miniblogs and names of contributors, news articles, e-mails and sender names, and other text that represents navigation information, road guidance information, operation instruction information, etc. Refers to data, etc. The text data may be image data representing a text.

  The display attribute refers to information representing a display mode of characters when characters included in the text data are displayed on the display unit 110. For example, font size, character color, character thickness, font type, character scroll speed, character display position, character display time, and the like are specific examples of display attributes.

  As a result, the user can more easily identify some characters of the text data whose display attributes have been changed.

  As a result, the user can infer the contents of the entire sentence data from some characters of the identified sentence data. Also, even if the text data is long and it is difficult to guess the contents of the text data as a whole, whether the text data is information that should be read immediately from some characters of the identified text data It is possible to determine whether the information is not at an earlier timing.

  Further, as shown in FIG. 2B, which will be described later, the display attribute change processing unit 190 changes the font size for a predetermined number of characters or words from the beginning of the sentence data that is a part of characters or words of the sentence data. Processing may be performed.

  For example, when the user browses the text data of the miniblog described above, the text data posted by the poster is usually displayed after the name of the poster, as shown in FIG. Is displayed.

  On the other hand, in the example of FIG. 2 (B), a process for changing the font size, which is one of the display attributes, is performed on the first two characters of the sentence data that is a part of the posted sentence data. The character whose size has been changed is displayed on the display unit DS.

  In an example of a miniblog like this example, the user often determines whether or not the information is to be read now by looking at the poster name. Therefore, if the font size of the contributor's name is made larger than usual as in this example, the user can determine whether or not to read the text data displayed on the display unit 110 at an earlier timing. become.

  When a news article as shown in FIG. 3 is displayed, the user often estimates the outline of the text data from words representing the field of news such as “economy” and “politics”. Therefore, when displaying a news article, the font size of a word representing the news field may be enlarged and displayed at the beginning of the sentence. FIG. 3 shows an example in which text data is scroll-displayed on the display unit DS. At timings T1 and T2, the character “Economy” is displayed on the display section DS, and scrolling is started after timing T2, “Nikkei” at timing T3, “average” at timing T4, and at timing T5. Indicates a state in which the characters “10,000 yen” are displayed on the display unit DS.

  In addition, there are many words in Japanese that can be understood with a single character such as kanji. For example, if you see the word “politics” in a news article, you can guess that the news article is an article about “politics”. In addition, in a mini blog or the like that the user regularly checks, it can be determined that the posting is “Yamada” by looking at the first letter “Yama” in the name of the contributor.

  Therefore, the display attribute change processing unit 190 may perform a font size change process on one character of the text data.

  As a result, for example, it is possible to change the display attribute of one character that expresses the content of the sentence data in the sentence data.

  On the other hand, for example, in English, it is almost impossible to guess the contents of a sentence with one letter of the alphabet. Therefore, when displaying English sentence data, it is desirable to change the display attribute in units of words.

  In addition, the display attribute change processing unit 190 sets the first character or the first word in the text data as the first display attribute, and the second character or the second character different from the first character in the text data. You may perform the display attribute change process which sets the 2nd word different from a 1st word to the 2nd display attribute different from a 1st display attribute.

  For example, as shown in FIG. 2C, the “mountain” that is the first character WD1 is displayed with the font size 72pt that is the first display attribute, and the second character WD2 that is different from the first character WD1 is displayed. A certain “now” is displayed with a font size of 66 pt which is the second display attribute. FIG. 2C shows a state in which characters displayed on the display unit DS are scrolled in the SC direction. In this example, the first display attribute and the second display attribute are different display attributes, but the first display attribute and the second display attribute may be the same display attribute.

  This makes it possible to change display attributes of at least two characters in the text data. If the display attribute can be changed for each character (character string) in this way, it is possible to adjust the degree of emphasis for each character (character string) and adjust the ease of recognition of the user's character.

  Specifically, the font size of the character to be emphasized can be increased. In addition, if the character to be emphasized is arranged at the head of the sentence, it becomes easier to guess the contents of the entire sentence at an earlier timing or to determine whether the information should be read immediately.

  Therefore, the display attribute change processing unit 190 sets the first character or the first word in the sentence data to the first font size, and the second character after the first character in the sentence data. Or you may perform the display attribute change process which sets the 2nd word behind the 1st word to the 2nd font size smaller than the 1st font size.

  As a result, it is possible to make it easier for the user to guess the content of the entire sentence, to determine whether the information should be read immediately, or the like at an earlier timing.

  As described above, for the first character displayed in a large font size, the user is warned, and the user decides whether or not the displayed text data should be read immediately. However, if attention is paid to the displayed characters indefinitely, attention to the front may be lost.

  Therefore, as shown in FIG. 2C and FIG. 3, the display attribute change processing unit 190 may perform the display attribute change process so that the font size decreases as the text data moves from the beginning to the end of the sentence. Good.

  Thus, if the font size of the displayed character is reduced, the user's attention is often directed to the outside world. On the other hand, even if the font size is reduced, if the user wants to read the text, the user can read it while ensuring safety, for example, by stopping.

  As a result, it is possible to keep the user's attention away from the characters displayed on the display unit 110 forever.

  Further, when the display control unit 120 displays the characters or words included in the text data on the display unit 110, the display attribute change processing unit 190 performs a display attribute change process on the displayed characters or words, When the display control unit 120 displays a specific punctuate included in the text data on the display unit 110, the specific punctuation is displayed on the display unit without performing display attribute change processing for the specific punctuation displayed. 110 may be displayed.

  Here, the term “about” refers to a generic name of descriptive symbols used for describing a language. The specific punctuation mark is a punctuation mark that is designated in advance as a irreducible object that is not subject to display attribute change processing, and refers to, for example, punctuation marks, question marks, parentheses, and accents. On the other hand, dance characters such as “Tomo” among the punctuation objects may be the target of the display attribute change process in the same manner as the characters.

  As a result, it is possible to display a specific punctuation that rarely expresses the meaning of the entire sentence without emphasizing it, and it is possible to display characters that express the meaning of the entire sentence in a relatively emphasized manner.

  As another example, as shown in FIG. 2D, the name “Yamada” of the miniblog is changed to “YAMAADA” in Roman letters, or as shown in FIG. An icon image representing a contributor may be displayed as the background image PIM while the text data regarding is displayed. Note that changing from Japanese notation to Roman notation or displaying a background image may be performed not only in the miniblog example but also in other examples.

  In the present embodiment, specifically, the display control described above is realized by the following method.

  That is, the head-mounted display device 100 of the present embodiment may include an information acquisition unit 130 that acquires character or word attribute setting information of text data from outside the head-mounted display device 100. And the display attribute change process part 190 may perform the display attribute change process about the character or word of sentence data based on the acquired attribute setting information.

  Here, the attribute setting information refers to information indicating display attributes of characters or words.

  Specifically, in the example of FIG. 4, an example is shown in which attribute setting information of PF-1 to PF-n is used. For example, in the attribute setting information PF-1 in FIG. 4, the font type is set to Gothic B (B is an abbreviation for bold) and the font size is set to 40 pt for the first to fifth characters. Scrolls automatically from right to left at a speed of 30% of the screen every second, and for the sixth and subsequent characters, set the font type to Mincho and the font size to 20pt, every second This indicates that scrolling is automatically performed from right to left at a speed of progressing by 50% of the screen.

  Further, the attribute setting information may be acquired from a device external to the head-mounted display device 100, such as the terminal device 200, the server device 300, the storage device 400, or the like. It may be input and set by the user via the user interface unit or the like.

  As a result, it is possible to change the display attribute of text data in the text data according to the attribute setting information to be used. The attribute setting information can be easily created, for example, in a format such as PF-1 shown in FIG. 4, so that the display attribute can be easily changed.

  In addition, the head-mounted display device 100 according to the present embodiment may include an attribute setting information storage unit 140 that stores attribute setting information acquired by the information acquisition unit 130. And the information acquisition part 130 may acquire the identifier of the attribute setting information linked | related with text data. Further, the display attribute change processing unit 190 may perform a display attribute change process on the text data based on the attribute setting information associated with the acquired identifier.

  For example, in the example of FIG. 4, the attribute setting information PF-1 to PF-n is stored in the attribute setting information storage unit DB. Then, when acquiring the text data TD, the identifier of the attribute setting information is also acquired.

  Here, the identifier of the attribute setting information refers to information indicating any of the attribute setting information. For example, the identifier of the attribute setting information indicates a number assigned to each attribute setting information, link information to a location where the attribute setting information is stored, or the like.

  Next, the attribute setting information indicated by the acquired identifier DIF is acquired from the attribute setting information PF-1 to PF-n stored in the attribute setting information storage unit DB. In this example, since “3” is acquired as the identifier DIF, the attribute setting information PF-3 corresponding to the identifier “3” is acquired.

  Then, based on the acquired attribute setting information PF-3, the text data TD is displayed on the display unit DS.

  Accordingly, it is not necessary to acquire attribute setting information every time the text data is displayed, and it becomes possible to reduce the amount of communication between the head-mounted display device 100 and the external device.

  In addition, the head-mounted display device 100 according to the present embodiment stores the attribute setting information that stores the first attribute setting information of the characters or words of the text data and the second attribute setting information different from the first attribute setting information. An information storage unit 140 may be included. Then, the display attribute change processing unit 190 performs display attribute change processing on the text data based on the first attribute setting information until a predetermined timing, and after the predetermined timing, based on the second attribute setting information. The display attribute may be changed for the text data.

  This makes it possible to change display attributes for the same character as time elapses.

  In addition, the display attribute change processing unit 190 may perform a display attribute change process on the text data based on attribute setting information indicating a font size, a character color, a character thickness, or a font type.

  This makes it possible to change the font size, character color, character thickness, or font type of the text data.

  Further, the display control unit 120 displays characters or words included in the sentence data on the display unit 110 without scrolling until a predetermined timing, and performs scroll display of the characters or words included in the sentence data after the predetermined timing. You may start.

  Thereby, for example, it is possible to display a sentence head portion of sentence data for a long time. As a result, for example, even when the user has temporarily left his / her line of sight from the display unit 110, the user may fail to guess the content of the text data, or may fail to determine whether or not to read immediately. It becomes possible to reduce the possibility.

  The display unit 110 may display the text data so as to be superimposed on the external field of view.

  As a result, the user can quickly switch an object to be watched carefully between the text data and the outside world.

2.3 Process Flow Next, the process flow of the present embodiment will be described with reference to the sequence diagram of FIG.

  First, the information acquisition unit 130 acquires attribute setting information (T101). At this time, the information acquisition unit 130 may acquire a plurality of attribute setting information.

  Next, the attribute setting information storage unit 140 acquires attribute setting information from the information acquisition unit 130 (T102), and stores the acquired attribute setting information (T103).

  And the information acquisition part 130 acquires text data and an identifier (T104). At this time, the information acquisition unit 130 may acquire one identifier for one sentence data, or may acquire a plurality of identifiers for one sentence data.

  Next, the display attribute change processing unit 190 acquires an identifier from the information acquisition unit 130 (T105), and reads attribute setting information corresponding to the acquired identifier from the attribute setting information storage unit 140 (T106, T107). When a plurality of identifiers are acquired for one sentence data at timing T104, for example, the attribute setting information indicated by the first identifier is read during the first period, and the second period is read during the second period. Read the attribute setting information indicated by the identifier.

  Further, the display attribute change processing unit 190 acquires text data from the information acquisition unit 130 (T108), and changes the display attribute of the acquired text data using the attribute setting information acquired at timing T107 (T109).

  And the display control part 120 displays the text data which changed the display attribute on the display part 110 (T110, T111).

3. Second Embodiment 3.1 System Configuration Example Next, a configuration example of a head-mounted display device 100 according to a second embodiment is shown in FIG. The head-mounted display device 100 includes a display unit 110, a display control unit 120, a display attribute change processing unit 190, a partial region setting unit 150, and a motion sensor signal acquisition unit 160. The head-mounted display device 100 is not limited to the configuration shown in FIG. 6, and various modifications such as omitting some of these components or adding other components are possible. is there.

  Next, the connection of each part is demonstrated. The display control unit 120 is connected to the display unit 110. The display attribute change processing unit 190 is connected to the display control unit 120. The partial area setting unit 150 is connected to the display attribute change processing unit 190. The motion sensor signal acquisition unit 160 is connected to the partial region setting unit 150. The motion sensor 500 is connected to the motion sensor signal acquisition unit 160.

  Next, processing performed in each unit will be described. Since the functions of the display unit 110, the display control unit 120, and the display attribute change processing unit 190 are the same as those in the first embodiment, description thereof is omitted.

  First, the partial area setting unit 150 sets a partial area described later as a display area. The function of the partial area setting unit 150 can be realized by hardware such as various processors (CPU or the like), ASIC (gate array or the like), a program, or the like.

  Next, the motion sensor signal acquisition unit 160 acquires a motion sensor signal from the motion sensor 500. The motion sensor signal acquisition unit 160 may be a communication unit that communicates with the motion sensor 500.

  Then, the motion sensor 500 detects a motion sensor signal and performs transmission / reception processing of the motion sensor signal with the motion sensor signal acquisition unit 160. The motion sensor 500 is, for example, an acceleration sensor. In that case, an acceleration sensor signal is detected as a motion sensor signal. The acceleration sensor is composed of an element whose resistance value is increased or decreased by an external force, for example, and detects triaxial acceleration information. In addition, the acceleration sensor may be a six-axis acceleration sensor that detects a moment around the three axes in addition to the three-axis force. Furthermore, the motion sensor is not limited to an acceleration sensor, and may be an orientation sensor such as a geomagnetic sensor, a gyro sensor, or the like. The azimuth sensor measures the azimuth that the sensor is facing in an angle (0 ° to 360 °). The geomagnetic sensor is composed of, for example, an element whose resistance value or impedance value increases or decreases depending on the strength of the magnetic field, and detects triaxial geomagnetic information. A sensor having the functions of a geomagnetic sensor, an acceleration sensor, and a gyro sensor may also be used.

3.2 Method Next, the method of the present embodiment will be described.

  The head-mounted display device 100 of the present embodiment described above is an area smaller than the display area of the display unit 110, and a partial area associated with character or word attribute setting information of text data is used as a display area. A partial area setting unit 150 to be set may be included. And the display attribute change process part 190 may perform the display attribute change process about text data based on the attribute setting information linked | related with the partial area | region.

  For example, an example of a partial area is shown in FIG. In FIG. 7, a plurality of partial areas RP1 to RP5 are set in the display area DS of the display unit. Each partial area is associated with the attribute setting information described in the first embodiment. More specifically, attribute setting information AT1 is associated with the partial region RP1, and the attribute setting information AT1 defines display attributes with a font type of Gothic B and a font size of 18 pt. Similarly, other partial regions are as shown in FIG.

  Thereby, for example, when the display position of the character of the text data is a predetermined position in a partial area, the display attribute of the character is changed based on the attribute setting information associated with the partial area. Is possible.

  Specific examples are shown in FIGS. 8A to 8D. 8A to 8D show an example in which text data is scroll-displayed, and the display area DS is set with the partial areas RP1 to RP5 described with reference to FIG. And Further, attribute setting information AT1 to AT5 of FIG. 7 is associated with these partial areas RP1 to RP5.

  First, in FIG. 8A, the text data is scrolled from the right, and the display attribute of the character positioned in the partial area RP5 is changed based on the attribute setting information AT5 associated with the partial area RP5. Is displayed on the display unit. Specifically, the font type is Gothic B and the font size is 18 pt.

  In FIG. 8B, the font size of “8”, which is the character that has scrolled and entered the partial area RP4, is changed to 32 pt and displayed on the display unit.

  Further, in FIG. 8C, the font size of “8”, which is a character that has been further scrolled into the partial area RP3, is 48 pt, and the characters “king” and “child” that have entered the partial area RP4. "Is changed to 32 pt and displayed on the display unit.

  Thus, in this example, since the partial area is associated with the attribute setting information so that the font size increases toward the center of the display area DS, the character displayed at the position in front of the user is displayed. It will be displayed the largest. Therefore, when the partial area and the attribute setting information are set in this way, it becomes possible to make it easier to read the characters displayed in the center of the screen that is the front of the user.

  In addition, the head-mounted display device 100 according to the present embodiment may include a motion sensor signal acquisition unit 160 that acquires a motion sensor signal representing the movement of the user's body from the motion sensor 500. Then, the partial area setting unit 150 may set at least one of the position and size of the partial area in the display area based on the acquired motion sensor signal.

  For example, FIGS. 9A and 9B show an example in which a partial region is set based on the movement of the user's head.

  First, in this example, the motion sensor SE is provided in the head-mounted display device 100, and the movement HM of the user's head is detected based on the acquired motion sensor signal.

  Based on the detected movement of the head HM, at least one of the position and the size of the partial area is set.

  For example, in the initial state of FIG. 9B, it is assumed that the partial region RP is set at the position P1. At this time, when it is detected that the user's head has been moved to the right like HM in FIG. 9A, the position of the partial region RP is changed from the position P1 to the position P2, and then the user's head When the head is moved further to the right, the position of the partial region RP is changed from the position P2 to the position P3.

  Although not shown, not only the position of the partial area may be changed, but also the size of the partial area, for example, the width and height of the partial area may be changed.

  Note that the partial area does not necessarily have to be set so that the entire area of the display area DS is included in any of the partial areas as shown in FIG. A partial area may be set only for a partial area of the area DS.

  Thereby, the user can designate a character whose display attribute is to be changed or a partial area of the display area by moving the head.

  Further, as a modification, a direction sensor is mounted on both the user's head and body, the head direction and the body direction are detected, and the position of the head is determined based on the difference between the head direction and the body direction. The partial area may be set based on the identified position of the head.

  In addition, the display attribute change processing unit 190 performs display attribute change processing for text data using attribute setting information associated with the partial area until a given timing, and after the given timing, the partial area It is not necessary to perform the display attribute changing process on the text data using the attribute setting information associated with.

  For example, as shown in FIG. 10A, a case where a partial area RP is set in the display area DS and text data is scroll-displayed will be described.

  In this case, the display attributes of the characters in the partial area RP are changed based on the attribute setting information associated with the partial area RP as shown in FIGS. 10A and 10B until a predetermined timing. And display on the display unit. The predetermined timing is, for example, a timing 5 seconds after the scroll display of the text data is started. However, it is not limited to this.

  Then, after the predetermined timing, as shown in FIG. 10 (C), the display attribute is changed even for the character displayed at the position of the partial region RP in FIGS. 10 (A) and 10 (B). Without displaying on the display.

  At this time, as shown in FIG. 10C, the partial area RP may be erased or released after a predetermined timing so that the display attribute is not changed, or the partial area RP is set. However, characters may be displayed on the display unit without using the attribute setting information associated with the partial region RP.

  As a result, it is possible to cancel the highlighted character display without changing the character display attribute after a predetermined timing. Therefore, after a predetermined timing, it becomes possible to return the user's attention to the outside world.

  Specifically, it is determined as follows which attribute setting information associated with which partial area is used for each character of the text data.

  For example, the display attribute of a character overlapping with a partial area may be changed using the attribute setting information associated with the partial area. However, since the character differs in shape and size for each character, The process for determining whether or not the partial areas overlap is large in processing amount and not realistic.

  Therefore, the display attribute change processing unit 190 sets a determination region for the character or word displayed in the display region, determines whether or not there is an overlapping region between the determination region and the partial region, When it is determined that an area exists, display attribute change processing may be performed based on attribute setting information associated with a partial area determined to overlap with the determination area. The display control unit 120 may display characters or words corresponding to the determination area on the display unit 110.

  A specific example will be described with reference to FIGS. First, as shown in FIG. 11A, determination areas DR1 to DR16 are set for each character of text data displayed in the display area DS of the display unit.

  Here, the determination area is used to determine whether or not a character in which the determination area is set and an arbitrary partial area are associated with each other when the attribute setting information used for the text data is specified. An area to be set. The determination area is also called a bounding box, and is, for example, a rectangular area that includes the entire character. However, the determination area is not necessarily a rectangular area including the entire character inside, and may be an area having another shape. The determination area may be set for each character string instead of for each character. For example, when displaying English sentence data, it is better to set the determination area in units of words.

  Next, using the determination areas DR1 to DR16 set as shown in FIG. 11A, there is an overlapping area between the partial area RP and each determination area in order from the left as shown in FIG. 11B. Determine whether. In the example of FIG. 11B, the partial area RP has an overlapping area between the determination areas DR9 and DR10, and therefore, when the display attribute of only one character is changed. Therefore, it is necessary to determine which character display attribute corresponding to which determination area is to be changed. This determination method will be described in detail later.

  In FIG. 11B, for example, when it is determined that the display attribute of “meeting” that is a character corresponding to the determination region DR9 is to be changed, the “meeting” is performed using attribute setting information associated with the partial region RP. "Is changed, and the text data is displayed as shown in FIG. It is assumed that a font size larger than the font size of the other region is set in the attribute setting information associated with the partial region RP.

  As a result, it is possible to determine which partial area to use attribute setting information associated with which character by using the same method while reducing the processing amount.

  Further, the display attribute change processing unit 190 scrolls and displays characters or words included in the text data on the display unit 110, and overlaps between the determination region and the partial region set for the scrolled characters or words. When it is determined that an area exists, display attribute change processing may be performed based on attribute setting information associated with a partial area determined to overlap with the determination area.

  As a result, it is possible to change the display attribute by determining whether or not there is an overlapping area even for text data that cannot be displayed in the display area at a time.

  In addition, as shown in FIG. 11B described above, when there is an overlap area between two determination areas for one partial area and the display attribute of only one character is changed, for example, As described below, it is determined which display area of the character corresponding to which determination area is to be changed.

  In other words, the display attribute change processing unit 190 includes the first partial area associated with the first attribute setting information of the character or word and the second partial area associated with the second attribute setting information of the character or word. Is set as the display area, and if the determination area overlaps with the first partial area and does not overlap with the second partial area, the text data is based on the first attribute setting information. When the display attribute is changed for the text area and the determination area overlaps the first partial area and also the second partial area, the display attribute is changed for the text data based on the second attribute setting information. Processing may be performed.

  Here, the first partial area is one of the partial areas that can be set to an arbitrary position, size, and shape in the display area. The second partial area is a partial area that is set at a position different from the first partial area in the display area and can be set to an arbitrary size and shape. Furthermore, a third partial area, which will be described later, is a partial area that is arranged at a position different from the first partial area and the second partial area in the display area and can be set to an arbitrary size and shape. Note that the number of partial areas set in the display area is not limited to two or three. In this example, the partial areas do not overlap each other.

  A specific example will be described with reference to FIGS. First, in the example of FIG. 12A, it is assumed that three partial areas RP1 to RP3 and 16 determination areas DR1 to DR16 surrounding each character are set.

  For example, the determination area DR11 has an overlapping area AR1 (the overlapping area AR1 is equal to the entire determination area DR11) between the partial area RP1 (corresponding to the first partial area described above), and the partial areas RP2 and RP3. There is no overlapping area between them (corresponding to the second partial area described above). Therefore, as shown in FIG. 12B, the character “T” corresponding to the determination region DR11 is displayed based on the attribute setting information (corresponding to the first attribute setting information described above) associated with the partial region RP1. To change.

  On the other hand, the determination region DR10 has an overlapping region AR2 between the partial region RP1 (corresponding to the first partial region described above) and the partial region RP2 (corresponding to the second partial region described above). It has an overlap area AR3. Therefore, in this example, the attribute setting information (corresponding to the second attribute setting information described above) associated with the partial area RP2 as shown in FIG. The display attribute is changed based on the display.

  Similarly, the determination region DR9 has an overlapping region AR4 between the partial region RP2 (corresponding to the first partial region described above) and the partial region RP3 (corresponding to the second partial region described above). Has an overlapping area AR5. Therefore, in this example, the attribute setting information associated with the partial area RP3 (corresponding to the second attribute setting information described above) for the character “meeting” corresponding to the determination area DR9 as shown in FIG. The display attribute is changed based on the display.

  As a result, when a partial area and a judgment area are newly overlapped by scrolling, it is possible to change display attributes using attribute setting information associated with the newly overlapped partial area. become.

  In addition, the display attribute change processing unit 190 includes a first partial area associated with the first attribute setting information of a character or a word and a second attribute information associated with the second attribute setting information of a character or a word. When the partial area is set as the display area, the first overlap area where the determination area overlaps with the first partial area is the second overlap where the determination area overlaps with the second partial area When it is determined that the area is larger than the area, display attribute change processing is performed on the text data based on the first attribute setting information, and when it is determined that the second overlapping area is larger than one overlapping area. The display attribute may be changed for the text data based on the second attribute setting information.

  A specific example will be described with reference to FIGS. As described above, in FIG. 12A, the determination region DR10 includes an overlapping region AR2 (corresponding to the first overlapping region described above) with the partial region RP1 and an overlapping region AR3 (described above with the partial region RP2). 2 equivalent region). At this time, when the overlapping area AR2 and the overlapping area AR3 are compared, the overlapping area AR2 is larger than the overlapping area AR3. Therefore, in this example, as shown in FIG. 12C, the character “meeting” corresponding to the determination region DR10 is used as attribute setting information (corresponding to the first attribute setting information described above) associated with the partial region RP1. Display with display attribute based.

  Similarly, the determination area DR9 has an overlapping area AR4 (corresponding to the first overlapping area described above) with the partial area RP2 and an overlapping area AR5 (corresponding to the second overlapping area described above) with the partial area RP3. doing. At this time, when the overlapping area AR4 and the overlapping area AR5 are compared, the overlapping area AR4 is larger than the overlapping area AR5. Therefore, in this example, as shown in FIG. 12C, the character “meeting” corresponding to the determination area DR9 is used as attribute setting information (corresponding to the first attribute setting information described above) associated with the partial area RP2. Display with display attribute based.

  This makes it possible to change display attributes using attribute setting information associated with a partial area having a larger overlap area with the determination area.

  Further, when the font size of the character or word included in the text data is enlarged based on the attribute setting information, the display attribute change processing unit 190 enlarges the determination area corresponding to the character or word with the enlarged font size. Alternatively, it may be determined whether or not there is an overlapping area between the enlarged determination area and the partial area.

  For example, as shown in FIG. 12D, when the font size of the character corresponding to the determination region DR9 is increased, the determination region DR9 itself is also increased in accordance with the enlarged character.

  This makes it possible to match the timing for changing the display attribute of the character with the timing estimated from the appearance of the displayed character.

3.3 Process Flow Next, the process flow of the present embodiment will be described with reference to the flowchart of FIG.

  First, the display control unit 120 acquires text data (S101), and the partial region setting unit 150 sets a partial region (T102). As described above, the partial area may be set based on the motion sensor signal, or may be set at a preset arrangement position.

  Then, the display attribute change processing unit 190 sets a determination area for the character (character string) of the sentence data (S103), and an overlapping area (the overlapping area (between the set partial area and the arbitrarily selected determination area) ( It is determined whether or not a first overlapping area exists (S104). If the display attribute change processing unit 190 determines that an overlapping area exists, the display attribute change processing unit 190 determines whether or not another overlapping area (second overlapping area) exists (S105).

  When it is determined in step S105 that the second overlapping area exists, the display attribute change processing unit 190 corresponds to the overlapping area having the larger area between the first overlapping area and the second overlapping area. An area is selected (S106), and attribute setting information associated with the selected partial area is specified (S107). In this example, it is assumed that one determination area does not overlap with three or more partial areas for simplification of description.

  On the other hand, if it is determined in step S105 that the second overlapping area does not exist, the display attribute change processing unit 190 specifies attribute setting information associated with the partial area corresponding to the first overlapping area (S107). ).

  Furthermore, when it is determined in step S104 that there is no overlapping area, the display attribute change processing unit 190 does not perform display attribute change processing for characters corresponding to the determination area. No specific processing is performed.

  Then, the display attribute change processing unit 190 determines whether or not the processing in steps S104 to S107 has been executed for all characters currently displayed in the display area in the text data (S108). ) If it is determined that the processing of step S104 to step S107 is not executed for all characters currently displayed in the display area in the text data, the processing of step S104 to step S107 is executed. The process of step S104-step S107 is performed about the character which has not been performed.

  On the other hand, if it is determined in step S108 that the processing in steps S104 to S107 has been executed for all characters currently displayed in the display area of the text data, the display attribute change processing unit 190 changes the display attribute for each character (character string) based on the specified attribute setting information, and the display control unit 120 displays the text data on the display unit 110 (S109). The display attribute change processing unit 190 does not perform display attribute change processing for characters for which attribute setting information is not specified, and the display control unit 120 displays the characters on the display unit 110.

  Thereafter, the display control unit 120 determines whether or not all of the text data has been scroll-displayed (S110), and if it is determined that all of the text data has been scroll-displayed, the process ends.

  On the other hand, when it is determined that not all of the text data has been scroll-displayed, the text data is scrolled (S111), and the process returns to step S104.

4). Third Embodiment 4.1 System Configuration Example Next, FIG. 14 illustrates a configuration example of a display processing system according to the third embodiment.

In this case, the user operation information acquisition unit 170 may be configured by, for example, a button, a keyboard, a mouse, a touch panel, or the like. In addition, the user operation information acquisition unit 170 may receive an acceleration sensor signal from an acceleration sensor, for example. In this case, the user operation information acquisition unit 170 may detect the user's body inclination or the like based on the acceleration sensor signal, and may detect the user's gesture. Note that the user operation information acquisition unit 170 may be included in the head-mounted display device 100 as illustrated in FIG. 14 or may be included in the terminal device 200.

  Then, the first communication unit 180 and the second communication unit 250 transmit / receive information to / from each other according to a communication standard such as WiFi (registered trademark) or Bluetooth (registered trademark).
