Description

PEN INPUT APPARATUS AND METHOD FOR OPERATING THE SAME

The present invention relates to a pen input apparatus and a method for operating the same, more particularly, to a pen input apparatus and a method for operating the same which may recognize a user’s pen input, without an auxiliary device.

With development of digital technology, users can write memos in various methods, using various digital devices. Specifically, users can write characters or draw pictures with a wireless pen mouse and written characters or pictures may be displayed on computers or notebooks. Users can write memos on smart phones or tablet PCs directly, using touch pens.

However, in case of writing letters with a conventional wireless pen mouse or touch pen, a user’s pen input accompanies movement of the touch pen (e.g., spacing between words). The movement of the touch pen has to be compensated to realize the user’s pen input accurately. For that, there have been various attempts to recognize and track the movement of the touch pen.

First of all, a pad exclusively used for coordinate recognition may be used so as to recognize movement of a touch pen. Electronic sensitized response between the pad exclusively used for coordinate recognition and a touch pen may be used, when a user uses a touch pen on the pad exclusively used for coordinate recognition, and coordinate setting for inputs created by the touch pen is enabled, such that the user’s pen input can be recognized based on the coordinate setting.

Another attempt is to use a communication device for location measurement. A location measurement device tracks movement of an electronic pen, while communicating with an electronic pen continuously. Especially, such a location measurement device measures a relative distance with an electronic pen through communication with the electronic pen to track a location of an electronic pen and then recognize locations between pen inputs made through the electronic pen.

A third attempt is to use a note exclusively used for coordinate recognition. A pattern formed on the note exclusively used for coordinate recognition is recognized, using an electronic pen including a camera, and locations between a user’s pen inputs can be recognized based on the recognized pattern.

However, such attempts require such auxiliary devices as the pad exclusively used for coordinate recognition, the location measurement device and the note exclusively used for coordinate recognition, and they have disadvantages of uneconomically high cost and user’s inconvenience.

Technology used for improving user convenience, while solving such disadvantages, is required.

In the drawings, the size and relative sizes of layers and regions may be exaggerated for clarity. Like reference numerals in the drawings denote like elements.

FIG. 1 is a diagram illustrating a pen input system 100 according to one embodiment of the present disclosure.

The pen input system 100 may include a pen input apparatus 110 and a terminal 120.

The pen input apparatus 110 is an apparatus which receives a user’s pen input to generate pen input data based on the user’s pen input. The pen input apparatus 110 replaces a conventional keyboard or mouse and it may be used in writing letters or drawing a picture. The pen input apparatus 110 may include an electronic pen and a pen mouse and the embodiments of the disclosure are not limited thereto. Various modifications for receiving a user’s pen input may be used.

The terminal 120 may be provided with the pen input data from the pen input apparatus 110 and display the pen input based on the pen input data. Examples of the terminal 120 may include a smart phone, a tablet PC, a notebook and a computer and the examples are not limited thereto. Any external devices capable of transmitting/receiving data to/from the pen input apparatus 110 and displaying pen input.

FIG. 2 is a block diagram illustrating a pen input apparatus 200 according to one embodiment of the present disclosure.

The pen input apparatus 200 may include a touch sensing unit 210, an optical sensing unit 220, a motion sensing unit 230, a pen input analyzing unit 240, a communication unit 250, a memory unit 260 and a user interface unit 270.

The touch sensing unit 210 may sense touch generated by pen input. When the user makes pen input, the pen input apparatus 200 may touch an external object (e.g., paper and a pad). The touch sensing unit 210 may sense such touch and determine whether the user performs pen input. To make it easy to sense contact with the external object after the pen input is generated, the touch sensing unit 210 may be arranged in an end of the pen input apparatus 200. The touch sensing unit 210 may include a touch sensor and other various components.

The optical sensing unit 220 may sense a locus of the user’s pen input. The optical sensing unit 220 may irradiate light outside and sense motion of an end of the pen input apparatus 200, in other words, the locus of the user’s pen input. To sense the locus of the pen input easily, the optical sensing unit 220 may be arranged in the end of the pen input apparatus 200. As the optical sensing unit 220 senses the locus of the pen input by sensing a light reflected after irradiating light, the touch sensing unit 210 sense touch input from the outside with a high recognition rate. However, even though the touch sensing unit 210 through various types of optical sensing units senses no touch with the outside, a locus of the pen input may be sensed in a predetermined range (e.g., a predetermined range of distances or recognition rates). The optical sensing unit 220 may include one or more of an optical sensor, a light emitting diode (LED), a laser sensor and a blue track sensor. When the optical sensor senses a light reflected on a desk or note after irradiated from the LED, the optical sensing unit 130 processes a signal transmitted from the optical sensor and recognize a locus of the pen input made by the pen input apparatus 100. The configuration of the optical sensing unit 220 is exemplary and other various configurations for sensing the locus of the input made by the pen input apparatus 100 according to embodiments of the present disclosure may be used.

The motion sensing unit 230 may sense overall motion of the pen input apparatus 200, in other words, change in states such as one or more of rotation, motion and slope on one or more shaft. For that, the motion sensing unit 230 may include one or more measuring sensors for sensing state change of the pen input apparatus 200. Such a measuring sensor may include one or more of an acceleration sensor, a gyro sensor, a geomagnetic sensor (e.g., a compass) and an electromagnetic field sensor. The components of the motion sensing unit 230 are one of examples and other various components may consist of the motion sensing unit 230 to sense change in states of the pen input apparatus 200.

The pen input analyzing unit 240 may generate pen input data. The pen input data is data on the user’s pen input and it may include a first pen input and a second pen input. The first pen input means a pen input accompanying touch such as characters or lines to realize through the pen input apparatus 200. The second pen input means a pen input accompanying no touch such as space between words. For example, a pen input for “기” includes a first pen input for “ㅣ” and a second pen input for space between “ㄱ” and “ㅣ”.

The analyzing of the pen input analyzing unit 240 may be performed based on result of sensing performed by the touch sensing unit 210, the optical sensing unit 220 and the motion sensing unit 230. Specifically, the pen input analyzing unit 240 may generate the first pen input accompanying the touch sensed by the touch sensing unit 210 based on performance or non-performance of the pen input determined by the touch sensing unit 210 and the locus of the pen input sensed by the optical sensing unit 220. In other words, a locus of the pen input sensed by the optical sensing unit 220 while the touch sensing unit 210 is sensing touch may be generated as the first pen input. Hence, the second pen input accompanying no touch sensed by the touch sensing unit 210 may be generated based on performance or non-performance of the pen input determined by the touch sensing unit 210 and the state change sensed by the motion sensing unit 230. In other words, state change sensed by the motion sensing unit 230 while the touch sensing unit 210 is sensing no touch may be generated as the second pen input. When the first pen input and the second pen input are generated, the first pen input and the second pen input are combined, only to generate pen input data. When one of the first and second pen inputs is following the other, a start point of the one pen input is identical to a finish point of the other pen input to make it possible to realize continuous pen inputs accurately.

Moreover, the pen input analyzing unit 240 may generate a third pen input accompanying no touch based on performance or non-performance of the pen input determined by the touch sensing unit 210 and the locus of the pen input sensed by the optical sensing unit 220. In other words, the locus of the pen input sensed by the optical sensing unit 220 while the touch sensing unit 210 is sensing no touch may be generated as the third pen input. When the third pen input is generated, the second pen may be compensated by the third pen input. The locus of the pen input may be sensed by the optical sensing unit 220 at a high recognition rate, in case the touch sensing unit 210 senses touch. The locus of the pen input may be sensed in a predetermined range (e.g., a range of predetermined distances or recognition rates), even with no touch sensed by the touch sensing unit 210. Accordingly, the pen input analyzing unit 240 compensates the second pen input, using the third pen input such that motion of the pen input apparatus may be reflected in the pen input data.

Alternatively, the pen input apparatus 200 may no optical sensing unit 220 and the pen input analyzing unit 240 may generate pen input data based on sensing of the touch sensing unit 210 and the motion sensing unit 230. Specifically, the pen input analyzing unit 240 may generate a first pen input and a second pen input based on performance or non-performance of the pen input determined by the touch sensing unit 210 and the state change sensed by the motion sensing unit 230. In other words, the state change sensed by the motion sensing unit 230 while the touch sensing unit 210 is sensing touch may be generated as the first pen input. The state change sensed by the motion sensing unit 240 while the touch sensing unit 210 is sensing no touch may be generated as the second pen input. When the first pen input and the second pen input are generated, the pen input analyzing unit 240 may combine the first pen input and the second pen input and generate pen input data based on the combined pen input. When one of the first and second pen inputs is following the other in the pen input data, a pen input start point of the one pen input is identical to a pen input finish point of the other pen input such that continuous pen inputs may be realized accurately.

The communication unit 250 may transmit one or more of the pen input data generated by the pen input analyzing unit 240 and the pen input data stored in the memory unit 260 to an external terminal. The communication unit 250 may transmit the pen input data in real time or according to the operation of the pen input apparatus 200. For example, when the user interface unit 270 receives the user’s input about the transmission of the pen input data the communication unit 250, the communication unit 250 may transmit the pen input data stored in the memory 260. Alternatively, when the touch sensing unit 210 senses no touch, the communication unit 250 may transmit the pen input data stored in the memory unit 260 immediately or in a predetermined time. The communication unit 250 may communicate with the external terminal through a wire communication method (e.g., Universe Serial Bus (USB) and a mouse port (PS/2 port)) or a wireless communication method (e.g., Bluetooth, Infrared Data Association (InDA) and other RF communication). However, examples of the communication unit 250 are not limited thereto and various wireless communication methods enabling data communication may be applied.

The pen input data generated by the pen input analyzing unit 240 may be stored in the memory unit 260. The pen input data stored in the memory unit 260 may be transmitted to the external terminal by the communication unit 250. In one embodiment, when communication between the communication unit 250 and the terminal is not connected, the pen input data is stored in the memory unit 260. When the communication between the communication unit 250 and the external terminal is connected, the communication unit 250 may transmit the pen input data stored in the memory unit 260 to the external terminal.

The user interface unit 270 may receive the user’s input. The user’s input may include one or more commands for starting/finishing of the operation of the pen input apparatus and transmitting the pen input data. The user interface unit 270 may include a button, a touch sensing unit (or a touch sensor) and an input device (e.g., a joy stick and a joy wheel). Such the user interface unit 270 may be configured to be exposed outside the pen input apparatus 200 and a plurality of one type input devices or combined various input devices. Such configuration is one of examples and various configurations capable of receiving the user’s input may be applied according to embodiments of the present disclosure.

A writing material may be coupled to a writing material coupling unit (not shown). As the writing material is coupled to the writing material coupling unit, the pen input apparatus 200 may be also used as writing material. To ease the user’s usage of the writing material, the writing material coupling unit may be provided in an end of the pen input apparatus 200.

FIG. 3 is a diagram illustrating a pen input apparatus according to another embodiment of the present disclosure.

Referring to FIG. 3, a pen input device 300 includes a touch sensing unit 310, an optical sensing unit 320, a motion sensing unit 330, a pen input analyzing unit 340, a communication unit 350, a memory unit 260 and a user interface unit 370.

Descriptions of the touch sensing unit 310, the optical sensing unit 320, the motion sensing unit 330, the pen input analyzing unit 340, the communication unit 350, the memory unit 360 and the user interface unit 370 which are provided in the pen input apparatus 300 shown in FIG. 3 are the same as the descriptions of the touch sensing unit 210, the optical sensing unit 220, the motion sensing unit 230, the pen input analyzing unit 240, the communication unit 250, the memory unit 260 and the user interface unit 270 which are provided in the pen input apparatus 200 shown in FIG. 2, respectively.

The structure and type of the pen input apparatus 300 shown in FIG. 3 are examples. Various structures and types may be applied according to embodiments.

FIG. 4 is a diagram illustrating operation of the pen input apparatus according to one embodiment of the present disclosure.

Referring to FIG. 4 (a), the pen input apparatus may sense the operation of the pen input apparatus and generate

pen input

410, 430 and 450. The user pen input includes a pen input 410, a pen input 430 and a pen input 450 which are performed sequentially. The pen input 410 and the pen input 450 refers to pen inputs accompanying touch. The pen input 430 refers to a pen input accompanying not touch. The pen input apparatus generates pen input data based on the

pen inputs

410, 430 and 450. At this time, a pen input finish point 420 of the pen input is in accord with a pen input start point 420 of the pen input 430 to connect the

continuous pen inputs

41, 430 and 450 with each other. Also, a pen input finish point of the pen input 430 is in accord with a pen input start point 440 of the pen input 450.

The pen input data is displayed as shown in FIG. 4 (b). Referring to FIG. 4 (b), the

pen inputs

410 and 450 are the pen inputs accompanying touch and then displayed, with an outline or color. The pen input 430 is the pen input accompanying not touch and then displayed transparently. Accordingly, an entire character of “기” may be displayed.

FIG. 5 is a flow chart illustrating a method 500 for operating a pen input apparatus according to one embodiment of the present disclosure.

In a step (510), touch accompanied by the pen input may be sensed. In a step of 510, touch with an external object is sensed and it is determined whether the pen input is performed by the user.

In a step (520), a locus of the user’s pen input may be sensed. The step (530) of sensing the locus of the pen input performed may be performed while the step (510) of sensing the touch of the pen input is performed or in a predetermined range (e.g., a range of predetermined distances and recognition rates) even though the touch of the pen input is not sensed.

The step (530) may sense change in one or more rotation, motion and slope on one or more shafts.

A step (540) analyzes the performance of the pen input determined in the step (510), the locus of the pen input sensed by the step (520) and the state change sensed in the step (530), and generates the pen input data based on the result of the analysis. The pen input data means the data about the user’s pen input set in the position, considering the motion of the pen input apparatus 200.

In one embodiment, the method 500 may further include a step of transmitting the pen input data to an external terminal. The transmitting step may be performed by transmitting the pen input data in real time. Alternatively, the transmitting step may be performed by transmitting the pen input data according to the user’s input on the transmission of the pen input data. Also, the transmitting step may be performed by transmitting the pen input data immediately or in a predetermined time, when not touch is sensed in the step (510).

In another embodiment, the method 500 may further include a step of storing the pen input data. The stored pen input data may be transmitted to the external terminal immediately or in a predetermined time. For example, the storing step may store the pen input data, unless the communication with the external terminal is connected. After that, when the communication with the external terminal is connected, the stored pen input data may be transmitted to the external terminal.

In a further embodiment, the method 500 may further include a step of receiving the user’s input for one or more of starting/finishing of the operation of the pen input apparatus and transmitting of the pen input data.

In a still further embodiment, the method 500 may further include a step of coupling a writing material to an end of the pen input apparatus.

Referring to FIGS. 5 and 6, the step (540) may include a step (610) of generating a first pen input, a step (620) of generating a second pen input and a step (630) of combining the first pen input and the second pen input.

In the step (610, the first pen input accompanying touch may be generated based on performance or non-performance of the pen input determined in the step (510) and the locus of the pen input sensed in the step (520). In other words, the locus of the pen input sensed in the step (520) may be generated as the first pen input, while the touch is sensed in the step (510).

In the step (620), the second pen input accompanying no touch may be generated based on performance or non-performance of the pen input determined in the step (510) and the state change sensed in the step (520). In other words, the state change sensed in the step (520) may be generated as the second pen input, while the touch is sensed in the step (510).

In the step (630), the first pen input and the second pen input may be combined and the pen input data may be generated based on the combined pen input. In the step (630), when one of the first and second pen inputs follows the other one, a pen input start point of the one is in accord with a pen input finish point of the other one, such that the continuous pen inputs may be realized accurately.

Additionally, a step of generating a third pen input accompanying not touch based on the step (540), the step (510) and the step (520) may be further provided. In other words, the locus of the pen input sensed in the step (520) while no touch is sensed in the step (510) may be generated as the third pen input. The step (540) may further include a step of compensating the second pen input, using the third pen input, once the third pen input is generated.

Alternatively, the step 520 of the method 500 shown in FIG. 5 may be omitted. Accordingly, the step 540 may be performed by analyzing the pen input in the step 510 and the step 530 and generating the pen input data. Specifically, the step (540) may further include a step of generating a first pen input accompanying touch and a second pen input accompanying no touch based on performance or non-performance of the pen input determined in the step (510) and state change sensed in the step (530). In other words, the state change sensed in the step (530) while the touch is sensed in the step (510) may be generated as the first pen input. The state change sensed in the step (530) while no touch is sensed in the step (510) may be generated as the second pen input. After that, once the first pen input and the second pen input are generated, the step (540) may further include a step of combining the first pen input and the second pen input with each other to generate the pen input data. The combining step makes a pen input start point of the one in accordance with a pen input finish point of the other, when one of the first and second pen inputs follows the other. Accordingly, the continuous pen inputs may be realized accurately.
