Description

  The present invention relates to a technique for efficiently operating a display device that displays information.

  In the present day when many people come into contact with computers (computers) and machines, researches on so-called “human interfaces” are being conducted in order for humans to operate computers and the like efficiently. As a part of research on the human interface, various new operation input systems replacing keyboards and mice have been invented and proposed.

  For example, in Patent Document 1, a distance measuring unit is provided in an image display device, and depending on the distance between the screen of the image display device and an observer, the image is enlarged if it is close and reduced if it is far away. An image display device that performs display is disclosed.

  This uses a concept called “Consistency” in human interface research. It is the same as a magnifying glass that many people already know how to handle the enlargement / reduction of the display screen on a computer. By being configured so that it can be performed (consistently), an intuitive and simple display screen enlargement / reduction operation is possible.

In addition, the image display device is equipped with an acceleration sensor and gravity sensor, and an image display device configured to scroll the display screen up and down, left and right by tilting the device up and down, left and right, and a camera and image analysis software. Various technologies such as an image display device that displays an image in accordance with the movement of a viewer's hand or body have been disclosed.
JP-A-11-238124

  However, the above conventional techniques have the following problems. That is, even if information can be displayed in various display forms such as enlargement / reduction by an intuitive operation, the display by the operation, for example, enlargement / reduction beyond the user's expectation, etc. The problem is that the form does not necessarily reflect the user's intention.

  Also, in order to reflect the user's intention as faithfully as possible in the display form, the user can individually set the user settings, such as “double the display at a distance of 20 cm between the face and the device and three times at the 10 cm”. If it does, it will deviate from the basic philosophy of human interface, which provides an interface that can be operated even by information weak persons such as elderly people.

  In order to solve the above-described problems, the present invention acquires physiological information indicating, for example, a defense response in the body against a stress stimulus and other physiological information, and selects a display form presumed to be suitable for the user from the physiological information. Provided is a physiologically adaptive display device that displays information.

  Specifically, a physiological information sensing unit that can be worn on the body for acquiring physiological information, an information display unit that can display information in a plurality of forms, and display on the information display unit according to the acquired physiological information And a selection unit for selecting a form.

  In addition to the physiological information, the movement information indicating the physical movement state of the device itself is acquired, and if it is detected from the movement information, for example, the movement is performed, the physiological display is performed by selecting the information display form in consideration of the movement information. A mold display device is also provided.

  Specifically, in addition to the physiological information sensing unit, the information display unit, and the selection unit, it further includes an exercise information acquisition unit that acquires exercise information indicating its physical exercise state, and the selection unit further acquires This is a physiologically adaptive display device configured to make the selection according to the exercise information.

  According to the present invention configured as described above, it is possible to display information in a suitable display form adapted to the user's sensibility and senses, such as reflecting the user's operation intention and being less likely to feel stress, for example. it can.

  In addition, by feeding back the display that has been executed once (adapted to the user), it is possible to display information in a suitable display format without any special setting operations, etc., so a human interface that can be fully operated even by information vulnerable persons Can be provided.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to these embodiments, and can be implemented in various modes without departing from the spirit of the present invention.

  In the first embodiment, claims 1 and 3 will be mainly described. In the second embodiment, claims 2 and 4 will be mainly described.

  Example 1

    <Overview>

  FIG. 1 is a conceptual diagram for explaining an example of information display in the physiologically adaptive display device of the present embodiment. As shown in FIG. 1, this display device (1) measures the distance between the user and the device itself, for example, with an infrared sensor, and (2) A. When the user is moved away from the user's face, the display image is reduced so that the entire image is displayed. B. When the user's face is brought close to the user's face, a part of the display image is enlarged and displayed so as to be displayed up.

  (3) The physiologically adaptive display device of this embodiment measures the physiological information of the user at this time, here, for example, electrodermal activity (EDA), by a sensor attached to the user's body. In general, the EDA value varies depending on the stress response between stress and non-stress. Therefore, if the EDA value rises after the screen enlargement process, it is determined that the user feels stress because the enlargement rate does not match the user's operation intention, and (4) information is adjusted by adjusting the enlargement rate. Is displayed again.

  As described above, the physiologically adaptive display device of this embodiment can display information in a suitable display form that reflects the user's operation intention and does not feel stress or the like.

    <Functional configuration>

  FIG. 2 is a diagram illustrating an example of functional blocks in the physiologically adaptive display device of this embodiment. As shown in this figure, the “physiological adaptive display device” (0200) of this example includes a “physiological information sensing unit” (0201), an “information display unit” (0202), and a “selection unit” (0203). And).

  Note that the functional blocks of the apparatus described below can be realized as hardware, software, or both hardware and software. Specifically, if a computer is used, a CPU, a main memory, a bus, or a secondary storage device (a storage medium such as a hard disk, a nonvolatile memory, a CD-ROM or a DVD-ROM, and a reading drive for these media) Etc.), hardware components such as printing devices, display devices, other external peripheral devices, I / O ports for the external peripheral devices, driver programs for controlling the hardware, other application programs, and information input Examples include user interfaces that are used.

  In addition, these hardware and software process the program developed on the main memory with the CPU, and process, store, and output data stored on the memory and hard disk, and data input via the interface. It is used for processing or controlling each hardware component. The present invention can be realized not only as an apparatus but also as a method.

  A part of the invention can be configured as software. Furthermore, a software product used for causing a computer to execute such software and a recording medium in which the product is fixed to a recording medium are naturally included in the technical scope of the present invention (the same applies throughout the present specification). Is).

  The “physiological information sensing unit” (0201) can be attached to the body and has a function of acquiring physiological information.

  “Physiological information” refers to information indicating changes that occur in the autonomic nervous system, immune system, endocrine system, etc. due to biological activity, such as heart rate variability information, blood pressure information, pulse wave information, respiratory information, electrodermal activity information, Examples include sweating information, skin temperature information, and eye movement information.

  For example, if the physiological information sensing unit senses heart rate variability, there is a method of measuring and acquiring a heart rate using an electrocardiographic sensor. A method of measuring and acquiring blood pressure and pulse waves using a pressure sensor in close contact with the pulse can be mentioned. Examples of the respiration information include information obtained by measuring the amount of respiration and the types of components contained in expiration using a flow sensor or a gas phase sensor. An example of the electrodermal activity is a method in which an electrical potential sensor is attached to the skin and the electrical resistance of the skin is measured and acquired. In addition, there is a method of acquiring skin temperature information or eye movement information by measuring skin temperature with a thermosensor, or measuring eye movement by analyzing a pupil image captured with a camera mechanism in real time. .

  As described above, the “physiological information sensing unit” can be realized by various sensors as described above, an arithmetic unit that processes data detected by the sensor, data analysis software, and the like.

  For example, the heart rate variability information, blood pressure information, pulse wave information, respiratory information, electrodermal activity information, sweating information, skin temperature information, eye movement information, etc. acquired here are, for example, edited by Yoshinori Horie et al. As shown in the literature such as “How to measure biological functions for Japan” (Japan Publishing Service), it has been confirmed that it fluctuates due to stress reactions. That is, by acquiring such physiological information and selecting a display form corresponding to the physiological information as described later, it is possible to perform information display that does not cause the user to feel stress.

  Of course, the physiological information is not limited to the physiological information for determining the presence or absence of such a stress reaction. For example, the ocular moisture content information obtained by measuring the moisture content of the eyeball surface from the infrared reflection amount It may be. Then, whether or not the user is dry eye is determined from the information on the moisture content of the eyeball, and processing for switching the information display from the display display to the audio output is performed in order to prevent the deterioration of dry eye in the selection of the information display form described later. Also good.

  Alternatively, the user's perspiration amount is measured from the EDA value, which is physiological information, and a warm color portion is converted into a cool color using a correspondence table or the like and displayed for a user with a high perspiration amount in an information display section described later. Processing may be performed.

  In addition, when an electroencephalogram sensor is used to measure electroencephalogram as physiological information and it is determined to be a sleep state based on the electroencephalogram level, the brightness of the display screen, which is an information display section to be described later, is adjusted to be darker, or the speaker of the audio output It is also possible to perform processing such as adjusting the sound volume level to a lower level.

  In this embodiment, various physiological information is acquired in this manner, and information display according to the physiological information is executed as described later, so that information display adapted to the user can be performed according to the physiological reaction of the user. It can be done.

  The “information display section” (0202) is a display section that can display information in a plurality of forms.

  “Display in multiple forms” includes, for example, various changes in the display form of an image displayed on a display. As an example of the image display form, an enlarged form / reduced form, a dark backlight display form / bright backlight display form, a high-speed scroll display form / low-speed scroll display form, a window display form / tab display form, a Japanese translation display form / Foreign character translation display mode, warm color display mode / cold color display mode, image moving image (rich content) display mode / image image extraction display mode, BGM display mode / BGM non-display mode, and the like.

  In addition to “a plurality of display forms on the display” as described above, “display in a plurality of forms” includes, for example, a form of selectively outputting to a plurality of output display destinations. As an example of this form, text-based information is displayed in the form of a text image on the display / output in the form of a sound on the speaker. In this embodiment, the information display on the information display unit, which is performed in various forms according to the detection values by various sensors and the input commands from the input device, is expanded according to physiological information, for example. The rate and scroll speed are selected.

  3 and 4 are diagrams for explaining an example of a display form in the information display unit. As shown in (1) of FIG. 3, for example, when the distance measurement sensor such as an infrared sensor is provided in the apparatus, the distance to the user's face is measured, and the distance between the apparatus and the face becomes 10 cm from the first 20 cm. That is, when the user performs an operation to bring the device closer to the face (or to bring the face closer to the device), control is performed to enlarge the screen display using an enlargement factor determination function f (x) that changes the distance x. , And so on.

  In addition, the display mode of enlargement or reduction uses an acceleration sensor or the like in addition to the distance measurement sensor to detect the movement of the device back and forth, and display and enlarge the display image on the display screen. Also good. The display magnification may be determined using, for example, a predetermined function f (x) as described above, or using a table with distance numerical values as arguments. Further, it may be determined by other data. In the present embodiment, for example, the enlargement rate determined in this way is selected to be adjusted according to the stress reaction of the user indicated in the physiological information in the selection unit described later.

  Also, as shown in FIG. 3 (2), the tilt direction of the device is detected by a tilt sensor built in the device, for example, when the device is tilted to the right, the display screen is scrolled to the right. The display form etc. are also mentioned. Further, the scroll speed may be adjustable according to the tilt angle. In this embodiment, for example, the scroll speed determined in this way is selected to be adjusted in accordance with the stress reaction of the user indicated by the physiological information in the selection unit described later.

  Further, as shown in (3) of FIG. 4, for example, in a head-mounted display device provided with a sensor that detects which direction the line of sight is directed by measuring the amount of reflected infrared light received by an infrared phototransistor. Another example is a form in which a window indicated by the user's line of sight is enlarged and displayed in an operable state from among a plurality of windows displayed on the display screen. In the present embodiment, for example, the accuracy of such line-of-sight detection is selected so as to be adjusted according to the stress reaction of the user indicated by the physiological information in the selection unit described later.

  Further, as shown in (4) of FIG. 4, if the apparatus includes an illuminance sensor and the ambient brightness is equal to or less than a predetermined value, the display (output) is switched from output display to the display to sound output to the speaker. ) Form. Or the display form etc. which adjust the backlight brightness | luminance of a display according to the brightness detection by an illumination intensity sensor are mentioned. In the present embodiment, for example, the brightness threshold value that is a criterion for such switching is selected so as to be adjusted according to the stress reaction of the user indicated in the physiological information in the selection unit described later. is there.

  As described above, in the information display unit of the present invention, for example, by performing image processing on an image displayed on a display with a graphic accelerator or the like, display in an enlarged form, display in a reduced form, scroll display, window selection display, output It is possible to display in a plurality of display forms such as destination switching display (output), display including / excluding rich contents and BGM, and so on. Therefore, in the next selection unit, a suitable display form can be selected from the plurality of display forms according to the physiological information acquired by the physiological information sensing unit.

  The “selection unit” (0203) has a function of selecting a display form on the information display unit (0202) according to the acquired physiological information.

  “Selection of display form according to physiological information” means that, for example, as described above, when the eye water content, which is physiological information, is equal to or lower than a threshold value indicating an abnormal dry value, the user is dry. In order to prevent the deterioration of the dry eye, the information display form may be switched from the display form to the sound output form.

  FIG. 5 is a conceptual diagram for explaining an example of selection by the selection unit. As shown in this figure, for example, an “EDA level-display processing content table” is held in the flash memory of the apparatus. Then, after the information is displayed on the information display unit, an EDA (electrical skin activity) value is measured by potential measurement. When the measured EDA level is below the standard level 5, it is assumed that stress reaction due to information display on the information display unit is not seen, and the magnification display process is doubled by reducing the distance between the device and the face by 10 cm. A normal enlargement / reduction process such as executing is performed.

  On the other hand, when the measured EDA level is 6 to 8, which is higher than the standard level, it is assumed that the user is stressed at the normal magnification, and for example, the magnification when the distance between the device and the face is brought closer to 10 cm is usually set. The process of enlargement processing is performed as 1.5 times the value. In addition, when the measured EDA level is 9 or higher, in addition to the process of lowering the magnification, the music that outputs stress is output or the display that uses the display color that reduces stress is performed. This process is also performed.

  In this way, according to, for example, the stress reaction indicated by the physiological information when the information is displayed, the scaling factor, scroll speed, visual line detection accuracy, output destination switching brightness threshold, and the like are changed and adjusted. Thus, it is possible to display information in a display form suitable for the user, such as reflecting the user's intention to operate and not feeling stress or the like, for example.

  Whether the user's stress response indicated by the physiological information is caused by overexpansion or insufficient enlargement rate may be determined by feedback, for example. Specifically, the information regarding the display form once selected and executed, whether the stress response has been reduced or increased further, is fed back, and reflected in the subsequent selection. In addition, for example, by holding the coefficient of the enlargement factor determination function in the flash memory and feeding it back to the subsequent selection, it is possible to display information suitable for the user without performing special user settings. .

    <Hardware configuration of this embodiment>

  FIG. 6 is a schematic diagram illustrating an example of a configuration of a physiologically adaptive display device when the above functional components are realized as hardware. The operation of each hardware component in the information display process adapted to the user's physiological state will be described using this figure. As shown in this figure, the physiologically adaptive display device includes a “CPU (central processing unit)” (0601) that performs various arithmetic processes, and a “main memory” (0602) that stores data calculated by the CPU. It is equipped with. Also provided is a “flash memory” (0603) that stores a program that is read into the main memory and executed by the CPU, and data necessary for executing the program. The “selection unit” is realized by these “CPU”, “main memory”, “flash memory”, and the like.

  Further, the “physiological information sensing unit” is realized by the “EDA value measurement sensor” (0604) worn by the user and the “I / O” (0605) that receives the measurement value of the sensor by wireless data communication. The “information display unit” is realized by a “video processing circuit” (0606) including a video chip and a “display” (0607).

  In addition, a “distance measurement sensor” (0608) for the user to operate information display on the “display” is also provided. They are connected to each other via a data communication path such as a “system bus” to transmit / receive information and process information.

  In addition, the “main memory” provides a work area that is a work area of the program at the same time that it is expanded to execute the program stored in the “flash memory”. In addition, a plurality of memory addresses are assigned to each of the “main memory” and “flash memory”, and programs executed by the “CPU” exchange data with each other by specifying and accessing the memory addresses. It is possible to perform processing.

  Here, for example, text information and image information acquired by an Internet connection function and a video playback function (not shown) are processed by a “video processing circuit” including a graphic accelerator and a video memory, and the image and the image information are displayed on the “display”. The text is displayed.

  The “distance measuring sensor” outputs an ultrasonic pulse, and executes a calculation on the sensor chip using the reflection time as a variable, thereby measuring the distance between the user's face and the display device. Then, according to the measured distance between the user's face and the display device, the “video processing circuit” executes image / text enlargement / reduction processing, which is enlarged / reduced and displayed on the “display”.

  For the enlargement / reduction processing in the “video processing circuit”, the display form determination program developed in the work area of the “main memory” first calculates the distance between the face measured by the “distance measurement sensor” and the display device. The indicated numerical value is stored at address 1 of “main memory”. Further, the enlargement factor determination function f (x) held at the address “α” of the “flash memory” is read and stored at the address 2 of the “main memory”. Then, using the numerical value indicating the distance stored at the address 1 as a variable x, the enlargement factor determination function f (x) is calculated by the calculation processing of “CPU”, and an enlargement factor such as double is calculated.

  Then, based on the calculated enlargement ratio, enlargement processing and anti-aliasing processing (enlarged image smoothing processing) of an image to be displayed by the “video processing circuit” are executed, and the display is enlarged and displayed on the “display”.

  The display form determination program also executes the following processing in order to adjust the display enlargement (reduction) display according to the physiological change of the user caused by the display enlargement (reduction) display, for example.

  First, at the timing when the enlarged display on the “display” is executed, the “EDA value measurement sensor” attached to the body of the user who is viewing the “display” is paired with the user's palm and finger. The potential difference between the electrodes is measured. Then, the measured EDA value is acquired by “I / O” of the display device by wireless data communication or the like, and stored in address 3 of “main memory”.

  Subsequently, the threshold value for determining the presence or absence of the stress reaction of the user held at the address “β” of the “flash memory” is read and stored at the address 4 of the “main memory”. Then, the “CPU” executes a size comparison process between the threshold and the EDA value. At this time, if the EDA value is less than the threshold value, the display form determination program indicates that the user does not show a stress reaction in the enlarged display twice the display, and the enlargement process is a display form adapted to the user. Judge.

  On the other hand, if the EDA value is equal to or greater than the threshold value, the display form determination program indicates that the user shows a stress response in the enlarged display twice the display, and the enlargement process is not a display form adapted to the user. Judge. Therefore, the enlargement processing calculation is performed again by changing the coefficient of the enlargement factor determination function and the information is displayed on the “display” at the recalculated enlargement factor. Further, the processing result is stored in the flash memory and fed back so that the calculated enlargement ratio is adjusted to be suitable for the user.

    <Process flow>

  FIG. 7 is a flowchart showing an example of a processing flow in the physiologically adaptive display device of the present embodiment. Note that the steps shown below may be processing steps that constitute a program for controlling a computer recorded on a medium. As shown in this figure, first, physiological information is acquired from a sensor attached to the body (of a user viewing the display screen) (step S0701).

  Subsequently, in accordance with the acquired physiological information, a display form on the information display unit is selected (step S0702), and information is displayed in the selected display form (step S0703).

    <Brief description of effect>

  As described above, the physiologically adaptive display device according to the present embodiment can display information in a suitable display form adapted to the user, for example, reflecting the user's intention of operation and, for example, being less likely to feel stress. it can.

  In addition, by feeding back the display that has been executed once (adapted to the user), it is possible to display information in a suitable display format without any special setting operations, etc., so a human interface that can be fully operated even by information vulnerable persons Can be provided.

  << Example 2 >>

    <Overview>

  The present embodiment is based on the first embodiment, and the physiological display type is characterized in that the information display form is selected according to the physical movement state of the apparatus itself in addition to the user's physiological state such as the presence or absence of stress. It is a display device.

  For example, if a predetermined acceleration pattern is not detected using an acceleration sensor, it can be determined that the physical motion state of the device (the user holding the device) is moving. It can also be determined from the acceleration value and acceleration time that the movement is due to walking. And since it is assumed that the user and this display device vibrate constantly during walking movement, the distance between the user's face and the device may be closer or farther than the user intends due to the vibration. There is sex.

  Then, for example, even if the user's face and the device approach 2 cm due to vibration, and the display screen enlargement processing is executed according to the approach, it is not due to the user's intention, so the selection of a suitable information display form for the user It cannot be said that has been made. Therefore, in this embodiment, for example, when the distance movement between the user's face and the device during walking is within ± 3 cm so that the enlargement / reduction processing is not performed due to such a vibration error during walking or the like, It is characterized in that the enlargement / reduction process is not selected.

    <Functional configuration>

  FIG. 8 is a diagram illustrating an example of functional blocks in the physiologically adaptive display device of the present embodiment. As shown in this figure, the “physiological adaptive display device” (0800) of the present embodiment is based on the first embodiment and includes “physiological information sensing unit” (0801), “information display unit” (0802), , “Selection unit” (0803). Since these “physiological information sensing unit” and “information display unit” are the same as those described in the first embodiment, detailed description thereof will be omitted.

  The feature point of the physiologically adaptive display device of this embodiment is that it further has a “exercise information acquisition unit” (0804). In addition, the “selection unit” is characterized by performing selection as described in the first embodiment in accordance with exercise information described later in addition to physiological information.

  The “exercise information acquisition unit” (0804) has a function of acquiring exercise information. “Exercise information” refers to information indicating the physical motion state of the subject, such as acceleration information, velocity information, angular velocity information, movement distance information based on position information, gravity information, vibration information, impact information, and the like. It is done.

  In addition, the exercise information acquisition unit that acquires such exercise information is realized by various sensors such as an acceleration sensor, for example, and acquires the image and calculates the movement distance by matching with the image before and after the time to acquire the exercise information. It may be realized by an imaging function or a video analysis circuit acquired as follows.

  In the case of an acceleration sensor, for example, if a predetermined acceleration pattern is detected, it can be determined that the physical motion state of the apparatus is moving. Further, it can be determined whether the movement is by walking or by using a moving means, based on the acceleration value.

  In the case of an angular velocity sensor, the rotational state of the apparatus and its speed can be determined from the detected angular velocity value. It is also possible to determine the fall state using the direction of acceleration and gravity information, and to determine the vibration state using vibration information.

  Then, using this acquired exercise information, for example, if it is determined that the physical movement state of the device is walking, the information display form suitable for the walking movement is selected and information is selected. Is displayed.

  The “selection unit” (0804) is configured to make the selection according to the acquired exercise information in addition to the physiological information.

  FIG. 9 is a diagram for explaining an example of selection that also includes exercise information in the selection unit of the present embodiment. As shown in this figure, as an information display form that also includes exercise information, for example, if it is determined from the acceleration information that is acquired exercise information that the exercise content is moving, the information display unit zooms in and out In the processing, there is a selection that the enlargement / reduction processing is not performed when the relative distance between the face and the apparatus is ± 3 cm.

  Further, for example, the momentum of the user who holds and moves the device is calculated according to the moving distance of the display device indicated by the acceleration information. If the momentum does not reach the initially set target value, the setting of the enlargement / reduction rate determination function is changed, and the enlargement / reduction is not selected and executed unless the device is moved longer than usual. The amount of exercise may reach the target value.

  In this way, information can be displayed by selecting a suitable information display form in consideration of exercise information in addition to physiological information.

    <Hardware configuration of this embodiment>

  FIG. 10 is a schematic diagram illustrating an example of a configuration in a physiologically adaptive display device when the above functional components are realized as hardware. The operation of each hardware component in the information display process adapted to the user's physiological state will be described using this figure.

  Note that the example of the hardware configuration of the physiologically adaptive display device shown in this figure is the same as in the first embodiment, which is the “CPU” (1001), “main memory” (1002), and “flash memory” (1003). ).

  In addition, “EDA value measurement sensors” (1004) and “I / O” (1005) worn by the user, which are physiological information sensing units, and “video processing circuit” (1006), which is an information display unit, (1007). A “distance measurement sensor” (1008) is also provided for the user to operate information display on the “display”.

  Further, a sensor such as an “acceleration sensor” (1009) that realizes a motion information acquisition unit is also provided, and these are connected to each other by a data communication path such as a “system bus” to perform transmission / reception and processing of information.

  Here, as in the first embodiment, for example, text information and image information acquired by an internet connection function and a moving image playback function (not shown) are processed by the “video processing circuit”, and the images and text are displayed on the “display”. Is displayed. The display form determination program executes arithmetic processing for calculating the enlargement / reduction ratio by the “CPU” according to the distance between the user's face measured by the “distance measurement sensor” and the display device, and the “video” By the enlargement / reduction process in the “processing circuit”, they are enlarged and reduced on the “display”.

  Further, for example, the enlargement / reduction display on the display is an enlargement / reduction rate according to physiological information indicating a user's stress response measured by the “EDA value measurement sensor” by the processing of the display form determination program similar to that of the first embodiment. A display form that suppresses the image is selected (the coefficient of the enlargement / reduction ratio determination function is changed).

  In addition, the display form determination program for the physiologically adaptive display device according to the present embodiment determines the information display form on the display which is the information display unit based on the exercise information acquired by the “acceleration sensor”. .

  Specifically, the display form determination program stores the numerical value of the acceleration of the apparatus itself detected by the “acceleration sensor” at address 1 of “main memory”. Then, the acceleration change pattern is pattern-matched with a change pattern at the time of walking that is held in advance, and if it matches, it is determined that the physical motion state of the apparatus is moving. Further, using a table or the like held in the flash memory, it is also determined that the user is moving by walking based on the acceleration value.

  Here, when it is determined that “the physical motion state of the device itself is“ walking ””, the display form determination program sets the numerical value of the threshold value stored in the address “β” of the “flash memory” to “main memory”. Is read out and stored at address 5. When it is detected by the “distance measurement sensor” that the face and the apparatus are approaching, the magnitude of the numerical value indicating the distance stored in the address 2 of the “main memory” and the threshold stored in the address 5 is large or small. The comparison process is executed by the “CPU” calculation process.

  As a result of the size comparison, if the distance is equal to or smaller than the threshold value, the distance between the face and the apparatus is not selected as enlargement / reduction as the information display form as a vibration error due to walking (no processing is executed). If the distance is equal to or larger than the threshold value as a result of the size comparison, the apparatus and the face are brought closer to each other according to the user's intention, and enlargement / reduction is selected as the information display form (processing is executed). .

    <Process flow>

  FIG. 11 is a flowchart showing an example of the flow of processing in the physiologically adaptive display device of this embodiment. Note that the steps shown below may be processing steps that constitute a program for controlling a computer recorded on a medium.
