Description

Input interface device for controlling an electronic device

The invention relates to a touch panel, in particular to an input interface device for controlling an electronic device.

Touch Panels have been widely used in home appliances, communications, electronic information and other product applications. Such as the currently widely used Personal Digital Assistant (PDA), various home appliances, game input interface. Through the integration of the touchpad and the display, the user can select the desired action, such as a personal digital assistant, various home appliances, and a game input interface, by using a finger or a stylus according to the function options on the display screen. Use the public system query tool, etc. to provide a convenient operating system.

According to different touch principles, touch panels are mainly classified into resistive, capacitive, optical, electromagnetic, and acoustic waves. The working principle of the capacitive inductive touch panel is to detect the coordinates of the touch position from the induced current generated by utilizing the capacitance change generated by the electrostatic combination between the arranged transparent electrodes and the human body. Compared with the resistive direct contact method, the capacitive sensing touch panel has better advantages in terms of transmittance, hardness, accuracy, reaction time, touch life, operating temperature, and starting strength, and It is not easy to damage, so it has been widely used.

There are two types of capacitive touch panels. The first type is a surface capacitive touch panel, and the second type is a projected capacitive touch panel. In general, surface capacitive touch panels are mostly single-touch detectors, while projected capacitive touch panels can be used for multi-touch detection. Currently, newer technologies have been applied to surface capacitive touch panels to enable multi-touch detection.

In addition to single-touch detection and multi-touch detection, capacitive touch panels are different from other touch panels, such as resistive touch panels, ultrasonic touch panels, and infrared touch panels. The capacitive touch panel forms a three-dimensional electric field different from the surface capacitance on the surface, so the capacitive touch panel generates an amount of induction due to the proximity of the finger before the actual touch occurs.

However, there is currently no specific application for this feature to manipulate detection. If this feature of the capacitive touch panel can be used, the application of the capacitive touch panel can be extended to the interactive field of three-dimensional.

The above description of the present invention and the following description of the embodiments of the present invention are intended to illustrate and explain the spirit and principles of the invention.

Figures 1A and 1B are schematic diagrams of the input interface device detecting the amount of sensing of a three-dimensional finger.

Referring to FIGS. 1A and 1B, the capacitive touch panel 10 of the input interface device has an X-axis electrode 12 located on the upper layer and a Y-axis electrode 14 located on the lower layer.

When the finger F1 is at a distance H1 from the capacitive touch panel 10, the capacitive touch panel 10 senses that the finger F1 is approaching to generate the sensing amount I1.

When the finger F2 is at a distance H2 from the capacitive touch panel 10, the capacitive touch panel 10 senses that the finger F2 is approaching to generate the sensing amount I2.

When the finger F3 is at a distance H3 from the capacitive touch panel 10, the capacitive touch panel 10 senses that the finger F3 is approaching to generate the sensing amount I3.

Referring to FIG. 2, the input interface device for controlling the electronic device can provide a user to control various electronic devices, such as various computers, various mobile phones, navigation devices, electronic dictionaries, various instruments, and the like.

The input interface device for manipulating the electronic device includes a capacitive sensing circuit 110 and a control unit 150.

The capacitive sensing circuit 110 is electrically connected to the control unit 150.

The capacitive sensing circuit 110 has a plurality of sensing points distributed in two dimensions, and the sensing points can sense that the handling objects (eg, fingers) respectively generate corresponding sensing amounts (ie, capacitance values). In other words, the capacitive sensing circuit 110 can output a sensing signal corresponding to the capacitance values of the sensing points.

The control unit 150 receives the sensing signal output by the capacitive sensing circuit 110 and analyzes the received sensing signal to perform a corresponding output.

The control unit 150 is configured to output a sensing signal according to the sensing signal and the first threshold, and calculate at least one touch coordinate and output the calculated touch coordinate by using the sensing signal according to the sensing signal and the touch threshold.

Here, the control unit 150 may compare the sensing signal with a first threshold. When there is a peak exceeding the first threshold in the sensing signal, the control unit 150 outputs the received sensing signal.

Moreover, the control unit 150 also compares the sensing signal with the touch threshold. When there is a peak exceeding the touch threshold value in the sensing signal, the control unit 150 further generates touch coordinates corresponding to all the peaks exceeding the touch threshold value in the sensing signal. The touch threshold is greater than the first threshold. That is to say, the touch threshold is relatively farther than the baseline of the sensing signal compared to the first threshold.

In other words, each sensing point of the capacitive sensing circuit 110 has a corresponding touch coordinate. When the distance between the manipulation object and the sensing point reaches the touch standard, that is, the distance between the two is less than a predetermined degree (for example, pressing thereon, contacting the surface thereof or the distance between the two is less than 0.1 centimeters (mm)), the control unit 150 A peak value exceeding the touch threshold value is calculated in the sensing signal, and a coordinate (ie, a touch coordinate) corresponding to the sensing point whose distance from the manipulation object is less than the specific degree is calculated.

In addition, the control unit 150 may further calculate at least one proximity coordinate and output the calculated proximity coordinate by using the sensing signal according to the sensing signal and the proximity threshold. The proximity threshold is less than the touch threshold and greater than or equal to the first threshold. That is to say, the proximity threshold is relatively close to the baseline of the sensing signal compared to the touch threshold. Moreover, the proximity threshold is relatively farther than the baseline of the sensing signal or equal to the first threshold compared to the first threshold.

Here, the control unit 150 may compare the sensing signal with the first threshold and the proximity threshold. When there is a peak between the first threshold and the proximity threshold in the sensing signal, the control unit 150 further generates the peak corresponding to each of the peaks between the first threshold and the proximity threshold in the sensing signal. Close to coordinates.

In other words, when the distance between the manipulated object and the sensing point is close to the standard, that is, the distance between the two is within a predetermined range (for example, the distance between the two is less than 2-5 cm (cm) and the touch standard is not met). The control unit 150 calculates that there is a peak between the first threshold and the proximity threshold in the sensing signal, and calculates a coordinate corresponding to the sensing point where the distance from the manipulation object falls within the specific range. (ie, near coordinates).

In this case, the control unit 150 can directly compare the received sensing signal with each threshold value, or first perform domain conversion of the sensing signal (eg, spectrum conversion), and then convert the sensed signal after the domain conversion. The cutoff values are compared. Wherein, the sensing signals compared with the respective threshold values may be the same or different domain modes.

The control unit 150 can be implemented by a single integrated circuit or by a plurality of integrated circuits.

The proximity gesture signal is a movement trajectory of the corresponding manipulation object within the effective sensing range of the sensing point.

Here, the trajectory analysis unit 170 may compare the sensing signal with a first threshold. When there is a peak greater than the first threshold in the sensing signal, the trajectory analyzing unit 170 may obtain a block formed by a peak larger than the first threshold, and analyze a relative position change of the block in the continuous output period to The corresponding proximity trajectory is obtained, so as to know the gesture formed by the corresponding manipulation object. In other words, the proximity trajectory corresponds to the movement trajectory of the manipulation object within the proximity sensing range of the sensing point. Moreover, the control unit 150 may output a proximity gesture signal corresponding to the proximity track to indicate an execution action of the corresponding application of the back end.

The control unit 150 and the trajectory analysis unit 170 may be implemented by a single integrated circuit, or by a two-integrated circuit, or even by more integrated circuits (ie, three or more).

In addition, under the permission of the processing capability of the control unit 150, the trajectory analysis unit 170 may not be separately provided to calculate the proximity gesture signal, but the function of the trajectory analysis unit 170 may be performed by the control unit 150. Moreover, the control unit 150 may not output the sensing signal, but instead output the proximity gesture signal after calculating the proximity gesture signal.

Moreover, the control unit 150 can also output a hovering gesture signal according to the change of the generated proximity coordinate in the continuous output period.

In this case, the control unit 150 can analyze the changes of each of the proximity coordinates in the continuous output period to obtain respective hovering trajectories, so as to know the gesture formed by the corresponding manipulation object. In other words, the hovering trajectory is the trajectory of the movement within the proximity sensing range of the sensing points of the manipulation object. Moreover, the control unit 150 may output a hovering gesture signal corresponding to each hovering trajectory to indicate an execution action of the corresponding application of the back end. Wherein, a trajectory analysis unit may be additionally provided to perform calculation of the hovering gesture signal.

The control unit 150 can also output a touch gesture signal according to the change of the generated touch coordinates in the continuous output period.

In this case, the control unit 150 can analyze the changes of the touch coordinates in the continuous output period to obtain corresponding touch trajectories, so as to know the gesture formed by the corresponding manipulation object. In other words, the touch track is a movement track corresponding to the touch sensing range of the sensing points of the control object. Moreover, the control unit 150 can output a touch gesture signal corresponding to each touch track to indicate an execution action of the corresponding application of the back end. Wherein, a trajectory analysis unit may be additionally provided to perform calculation of the touch gesture signal.

As can be seen from the foregoing, according to the output data, the types of execution modes that the control unit 150 can have include a touch detection mode to a proximity detection mode.

The touch detection mode further includes a first execution mode and a fourth execution mode. The proximity detection mode further includes a second execution mode, a third execution mode, a fifth execution mode, and a sixth execution mode.

In the first execution mode, the control unit 150 executes a corresponding operation program to output a touch coordinate.

Moreover, the control unit 150 can enable the comparison procedure of the sensing signal and the touch threshold value and/or the enable sensing signal and the proximity threshold when it is determined that there is a peak value greater than the first threshold value in the sensing signal. The comparison program for values. Similarly, the control unit 150 may also be configured to enable the comparison between the sensing signal and the touch threshold when it is determined that there is a peak between the first threshold and the proximity threshold.

Referring to FIG. 7B, it can be observed from the figure that the sensing range 92 is the sensing range of the X-axis electrode X2 in the A-A section, and the maximum sensible distance is Dmax. When the object enters the sensing range of different relative heights D2, D3, D4, D5, the charging and discharging circuit 118 generates different multi-order proximity data.

For the calculation of the proximity gesture signal, the control unit 150 or the trajectory analysis unit 170 may calculate a central feature value and at least one edge feature value of each of the operating objects according to the sensing signal, and calculate each sensing signal according to the central feature value and the edge feature value. The shape of the object (for example: palm shape), and then according to the movement of the central feature value and the change of shape to generate gestures.

The capacitive sensing circuit 110 can detect the proximity data generated by the plurality of operating objects, for example, a hand motion that may be generated by one hand, or a hand motion that may be generated by the hands. Or, hand movements generated by many people and more. Here, the central feature value, the edge feature value, and the like representing each of the operating objects can be calculated by the data characteristics of the proximity data output by the capacitive sensing circuit 110. After the feature values of each of the operating objects are obtained, the shape of each of the operating objects can be calculated, and then the individual shape changes and the moving directions of the single operating object and the multi-operating objects can be calculated according to the change of the shape. Wherein, the moving direction may be a two-dimensional or three-dimensional moving direction. Finally, based on the moving direction and shape change of one or more operating objects, a final judgment can be obtained.

In the following, an example will be given of how to obtain the change pattern of the proximity data and the proximity data. Finally, the shape judgment and the gesture judgment are performed by preliminarily simulating the shape (hand shape) and shape change of different operation objects (hands).

8A is a schematic diagram of an embodiment in which the palm of the hand is turned into a flat palm shape, and the 8B-8D is a schematic diagram of the sensing signal detected by the sensing array 112 with respect to FIG. 8A.

In Fig. 8A, when the right hand 2 is at t=t1, it is a palm shape, that is, a shape of a hand knife with respect to the sensing array 112. When the right hand 2 is at t=tn, it is turned into a flat palm shape, that is, it is in a flat configuration with respect to the sensing array 112.

In FIG. 8B, when t=t1, the sensing array 112 detects the large-area proximity sensing signal 20 generated by the right hand 2, which is the sensing signal generated by the hand-knife portion of the right hand 2 approaching the sensing array 112. . Wherein, the darker portion is the one with a larger amount of induction, that is, the portion of the right hand 2 is closer to the portion of the sensing array 112; and the portion with a lighter color is smaller, that is, the right hand 2 The hand knife portion is farther away from the portion of the sensing array 112.

In FIG. 8C, at t=tn, the sensing array 112 detects the large-area proximity sensing signal 20 generated by the right hand 2, which is the sensing signal generated by the palm portion of the right hand 2 approaching the sensing array 112. . Wherein, the darker portion is the one with a larger amount of induction, that is, the palm portion of the right hand 2 is closer to the portion of the sensing array 112; and the lighter portion is the smaller one, that is, the right hand 2 The palm portion is farther away from the portion of the sensing array 112.

Looking at Figures 8A-8C, it can be seen that in the process of the right hand 2 being turned from a palm to a flat palm, the sensing array 112 produces a large area of proximity sensing signal 20 changes. From the large area proximity sensing signal 20 of Fig. 8B, the palm shape represented by it can be calculated, that is, the palm shape of the hand is similar to a rectangle. Similarly, the palm shape represented by the large-area proximity sensing signal 20 of FIG. 8C can be calculated, that is, the palm shape is flat.

Among them, the central feature value can be calculated by the centroid method or the watershed method to obtain the representative coordinates of the palm shape. The coordinate represented by the central feature value may be two-dimensional data or three-dimensional data. The movement of the palm shape can be calculated by the movement of the central feature value. For example, in the 8A-8C figure, the palm of the hand is flat and palm-shaped, and it can be easily seen that the two-dimensional central feature value changes, about from right to left. However, the movement of the Z axis is the process from bottom to top.

The specific movement process can be reversed, and a standard palm shape conversion and gesture database can be established in advance. In the actual detection, the fuzzy comparison method is used to compare the detected sensing data with the database, and then the actual gesture is determined.

9A and 9B are schematic diagrams of embodiments of left and right hand-knife-shaped right-to-left panning gestures (clap gestures); and 9C and 9D plans are relative to layers 9A and 9B, sensing arrays A schematic diagram of the sensed signals detected by 112.

Next, in FIG. 9A, when the right hand 2 and the left hand 3 are at t=t1, they are in the shape of a hand knife, that is, in the form of a hand knife with respect to the sensing array 112. When t=t1, the right hand 2 and the left hand 3 are respectively at the edge of the sensing array 112. In FIG. 9B, when the right hand 2 and the left hand 3 are at t=tn, they are also a palm shape, that is, a shape of a hand knife with respect to the sensing array 112. When t=tn, the right hand 2 and the left hand 3 are respectively at the center of the sensing array 112. That is, the 9A and 9B diagrams illustrate that the right hand 2 and the left hand 3 gradually approach each other, that is, the posture of the clapping player. This gesture can be discriminated via the input interface device for controlling the electronic device according to the present invention, and an appropriate gesture signal is output. For example, it may be referred to as a clapping gesture signal that is responsive to a gesture of movement that is retracted by the palm of the hand.

In FIG. 9C, at t=t1, the sensing array 112 detects the large-area proximity sensing signals 20, 30 generated by the right hand 2 and the left hand 3, which are the hand knife portion of the right hand 2 and the hand knife of the left hand 3, respectively. The portion approaches the sensing signal generated by the sensing array 112.

In FIG. 9D, at t=tn, the sensing array 112 detects the large-area proximity sensing signals 20, 30 generated by the right hand 2, which is the proximity sensing of the palm portion of the right hand 2 and the palm portion of the left hand 3. The sensed signals generated by array 112.

Looking at Figures 9A-9D, it can be seen that in the process of the right hand 2, the left hand 3 being moved from the edge of the sensing array 112 to the center by the palm of the hand, the sensing array 112 will produce a change in the large-area proximity sensing signals 20, 30. It is also moved from the edge to the center. That is, the palm shape has not changed, but the palm shape moves. Therefore, the palm shape represented by the large-area proximity sensing signals 20, 30 of Fig. 9C can be calculated, that is, the shape of the palm of the hand, which is similar to a rectangle. Similarly, the central feature values represented by the large-area proximity sensing signals 20, 30 of Fig. 9C can also be calculated. During the movement of the palm shape, the movement process of the central feature value can be represented, that is, the movement of the central feature value represents the movement of the palm shape.

However, as illustrated in Figures 8A-8C, the movement of the central eigenvalues must be moderately converted to truly represent the movement of the palm. As far as the user is concerned, this conversion process does not appear and the user does not care. It is important to note that the input interface device for manipulating the electronic device in accordance with the present invention can be used to sense the gestures of the user's palm movement and variation by sensing the proximity sensing signals of the array 112.

In the palm shape of the 9A~9D figure, it can be easily seen that the two-dimensional central feature value changes, about the right hand 2 moves from right to left and the left hand 3 moves from left to right, and the two gradually approach, that is, Shrinking (or shrinking) movement. There are no specific changes to its Z axis.

10A and 10B are schematic diagrams of an embodiment of clockwise and counterclockwise translation of the left and right hands, and 10C and 10D are respectively detected by the sensing array 112 with respect to FIGS. 10A and 10B, respectively. Schematic diagram of the sensing signal.

In Fig. 10A, when the right hand 2 and the left hand 3 are at t=t1, they are in the shape of a hand knife, that is, in the form of a hand knife with respect to the sensing array 112. When t=t1, the right hand 2 and the left hand 3 are respectively at the edge of the sensing array 112. In FIG. 10B, when the right hand 2 and the left hand 3 are at t=tn, they are also a palm shape, that is, a shape of a hand knife with respect to the sensing array 112. When t=tn, the right hand 2 and the left hand 3 are respectively at the bottom end of the sensing array 112. That is, FIGS. 10A and 10B illustrate that the right hand 2 and the left hand 3 respectively rotate in a counterclockwise direction and a clockwise direction, and assume a posture like a fan. This gesture can be discriminated via the input interface device for controlling the electronic device according to the present invention, and an appropriate gesture signal is output. For example, it may be referred to as a fan gesture signal that is responsive to gesture gestures that are moved in a manner that is retracted toward the body by the palm of the hand.

In FIG. 10C, at t=t1, the sensing array 112 detects the large-area proximity sensing signals 20, 30 generated by the right hand 2 and the left hand 3, which are the hand knife portion of the right hand 2 and the hand knife of the left hand 3, respectively. The portion approaches the sensing signal generated by the sensing array 112.

In FIG. 10D, at t=tn, the sensing array 112 detects the large-area proximity sensing signals 20, 30 generated by the right hand 2, which is the proximity sensing of the palm portion of the right hand 2 and the palm portion of the left hand 3. The sensed signals generated by array 112.

Looking at Figures 10A-10D, it can be seen that during the movement of the right hand 2, the left hand 3 by the palm of the hand from the edge of the sensing array 112 to the center, the sensing array 112 will produce a change in the large area proximity sensing signals 20, 30. It is also moved from the edge of the panel to the bottom of the panel. That is, the palm shape has not changed, but the palm shape moves. Therefore, the palm shape represented by the large-area proximity sensing signals 20, 30 of Fig. 10C can be calculated, that is, the palm shape of the hand is similar to a rectangle. Similarly, the central feature values represented by the large-area proximity sensing signals 20, 30 of FIG. 10C can also be calculated. During the movement of the palm shape, the movement process of the central feature value can be represented, that is, the movement of the central feature value represents the movement of the palm shape.

However, as illustrated in Figures 8A-8C, the movement of the central eigenvalues must be moderately converted to truly represent the movement of the palm. As far as the user is concerned, this conversion process does not appear and the user does not care. The important point is that the present invention can reverse the gesture of the user's palm movement and variation by sensing the proximity sensing signal of the array 112.

In the palm shape of the 10A~10D figure, it can be easily seen that the two-dimensional central characteristic value changes, about the right hand 2 rotates counterclockwise and the left hand 3 rotates clockwise, and the two gradually approach the bottom end of the sensing array 112. That is, the movement for the two hands to turn down. There are no specific changes to its Z axis.

11A and 11B are schematic views of an embodiment in which the left and right hands are turned into a flat palm shape; and the 11C-11E pattern is sensed by the sensing array 112 with respect to the 11A and 11B drawings. A schematic diagram of the measured signal.

In Fig. 11A, the right hand 2 and the left hand 3 are in the shape of a hand knife when t=t1, that is, in the form of a hand knife with respect to the sensing array 112. When t=t1, the right hand 2 and the left hand 3 are respectively at the edge of the sensing array 112. In Fig. 9B, when the right hand 2 and the left hand 3 are at t=tn, they are flat palms, that is, in a state of being flat with respect to the sensing array 112. When t=tn, the right hand 2 and the left hand 3 are respectively on both sides of the sensing array 112. That is, the 11A and 11B drawings illustrate that the right hand 2 and the left hand 3 are respectively turned into a flat shape in the form of a hand knife. This gesture can be discriminated via the input interface device for controlling the electronic device according to the present invention, and an appropriate gesture signal is output. For example, it may be referred to simply as a gesture signal, which is in response to a gesture pattern that covers the panel in the direction of the panel by the palm of the hand.

In FIG. 11C, at t=t1, the sensing array 112 detects the large-area proximity sensing signals 20, 30 generated by the right hand 2 and the left hand 3, which are the hand knife portion of the right hand 2 and the hand knife of the left hand 3, respectively. The portion approaches the sensing signal generated by the sensing array 112. Wherein, the darker part is the one with a larger amount of induction, that is, the hand knife portion of the right hand 2 and the hand knife portion of the left hand 3 are closer to the portion of the sensing array 112; and the lighter color portion is smaller for the sensing amount. That is, the hand knife portion of the right hand 2 and the hand knife portion of the left hand 3 are farther away from the portion of the sensing array 112.

In FIG. 11D, at t=tm, the sensing array 112 detects the large-area proximity sensing signals 20, 30 generated by the right hand 2, which is the proximity sensing of the palm portion of the right hand 2 and the palm portion of the left hand 3. The sensed signals generated by array 112.

In FIG. 11E, at t=tn, the sensing array 112 detects the large-area proximity sensing signals 20, 30 generated by the right hand 2, which is the proximity sensing of the palm portion of the right hand 2 and the palm portion of the left hand 3. The sensed signals generated by array 112.

Observing FIGS. 11A-11E, it can be found that in the process of the right hand 2, the left hand 3 being converted from the edge of the sensing array 112 to the flat palm shape to the sensing array 112 by the palm of the hand, the sensing array 112 generates a large area. The change in the proximity sensing signals 20, 30, that is, the palm shape has a tendency to gradually change. In Figure 11A, it can be judged that it is a palm shape. In Fig. 11B, it can be judged that it is a palm joint palm shape. In Fig. 11C, it can be judged that the palm is flat palm shape. The change of the palm shape can be calculated from the large-area proximity sensing signals 20 and 30 of the 11C~11E map respectively. Similarly, the central feature value represented by the large-area proximity sensing signal 20"30 of the 11C-11E picture can be calculated. During the movement of the palm shape, the movement process of the central feature value can be represented as That is, the movement of the central feature value represents the movement of the palm shape.

However, as illustrated in Figures 8A-8C, the movement of the central eigenvalues must be moderately converted to truly represent the movement of the palm. As far as the user is concerned, this conversion process does not appear and the user does not care. It is important to note that the input interface device for manipulating the electronic device in accordance with the present invention can be used to sense the gestures of the user's palm movement and variation by sensing the proximity sensing signals of the array 112.

In the 11A~11E figure, the change of the palm shape of the hand knife is flat, and the change of the center feature value of the two-dimensional can be easily seen. The center feature value of the two-dimensional right hand changes, about from right to left, and the left hand in contrast. However, the Z-axis movement of the right hand is the process from bottom to top and the left hand is the same.

12A and 12B are schematic views of an embodiment in which the right hand five-point palm shape is turned into a large palm shape (grabbing palm shape); and the 12C and 12D images are relative to the 12A and 12B images, the sensing array 112 Schematic diagram of the detected proximity sensing signal.

In Fig. 12A, the right hand 2 is a five-point palm shape at t = t1, that is, a shape of five points with respect to the sensing array 112. In Fig. 10B, when the right hand 2 is at t = tn, it changes to a single large palm shape, that is, a form in which the five fingers of the sensing array 112 are concentrated together.

In FIG. 12C, at t=t1, the sensing array 112 detects the large-area proximity sensing signal 20 generated by the right hand 2, which is the proximity of the top of the five fingers of the right hand 2 to the proximity sensing array 112. Sensing signal.

In FIG. 12D, when t=tn, the sensing array 112 detects the large-area proximity sensing signal 20 generated by the right hand 2, which is the sensing signal generated by the five-finger tip of the right hand 2 approaching the sensing array 112. .

Looking at Figures 12A-12D, it can be seen that in the process of the right hand 2 changing from a five-finger palm to a large palm shape, the sensing array 112 produces a large-area proximity sensing signal 20 change. From the large-area proximity sensing signal 20 of Fig. 12C, the palm shape represented by it can be calculated, that is, the five-point palm shape. Similarly, the palm shape represented by the large-area proximity sensing signal 20 of Fig. 12D can be calculated, that is, the large palm shape is larger than the individual dot area in Fig. 12C.

In the central eigenvalue, the five-point palm shape of the 12th to 12th graphs is changed to a single palm shape, and the two-dimensional central eigenvalue change can be easily seen, which is roughly moved from five points to a certain center. The movement of the Z axis is not obvious.

Next, an embodiment in which a gesture operation is performed with a single finger will be described.

FIG. 13A is a schematic diagram of an embodiment in which the palm of the hand is rotated counterclockwise; and FIG. 13B is a schematic diagram of the proximity sensing signal detected by the sensing array 112 with respect to FIG. 13A.

In Fig. 13A, the right hand 2 is a single point palm shape at t = t1, that is, a single point pattern with respect to the sensing array 112, and the right hand 2 approaches the sensing array 112 with the index finger. The right hand 2 performs a counterclockwise rotation during the process of t=t1~t=tn.

In FIG. 13B, when t=t1, t=tn, the sensing array 112 detects the movement of the large-area proximity sensing signal 20 generated by the right hand 2. The tip of the index finger of the right hand 2 is close to the sensing signal generated by the sensing array 112.

During t=t1~t=tn, the sensing array 112 can detect that the movement of the single point palm is a counterclockwise movement, and the palm shape does not move. Therefore, it is reflected in the change of the palm shape, and there is no palm shape change. However, in the change of the central eigenvalue, there is a movement of the central eigenvalue. Among them, the movement of the Z axis is not obvious.

Other various single-point palm-shaped changes can be constructed through the description of the above embodiments, and will not be described below.

Next, an embodiment in which the reduction gesture is performed with two fingers will be described.

14A and 14B are schematic views of an embodiment in which the palm of the right hand is turned into a two-point retraction (reduction gesture); and the 14C and 14D are relative to the 14A and 14B, the sensing array 112 Schematic diagram of the detected sensing signal.

In Fig. 14A, when the right hand 2 is at t=t1, the two fingers are open palms, that is, in the form of two points with respect to the sensing array 112. In Fig. 14B, when the right hand 2 is at t = tn, it is converted into a two-finger indented palm shape, that is, a form in which the two fingers of the sensing array 112 are concentrated together. When the two fingers are attached, a similar large palm shape will be formed.

In FIG. 14C, at t=t1, the sensing array 112 detects the large-area proximity sensing signals 21, 22 generated by the right hand 2, which are the top ends of the two fingers of the right hand 2 approaching the sensing array 112. The resulting sensing signal.

In FIG. 14D, at t=tn, the sensing array 112 detects the large-area proximity sensing signals 21, 22 generated by the right hand 2, which is the proximity of the two-finger tip of the right hand 2 to the sensing array 112. Sensing signal.

Looking at Figures 14A-14D, it can be seen that in the process of the right hand 2 changing from a palm to a palm shape, the sensing array 112 produces a large area of proximity sensing signals 21, 22. From the large-area proximity sensing signals 21, 22 of Fig. 14C, the palm shape represented by it can be calculated, that is, the two palms. Similarly, the palm shape represented by the large-area proximity sensing signals 21, 22 of Fig. 14D can be calculated, that is, the large palm shape, which is larger than the individual dot area in Fig. 14C.

In the central eigenvalue, the two palms of the 14A~14D map are transferred to a single palm shape, and the two-dimensional central eigenvalue change can be easily seen, which is roughly moved from two points to a certain center. The movement of the Z axis is not obvious.

Next, an embodiment in which the Z-axis direction is moved will be described.

Figure 15A is a schematic diagram of an embodiment of a right hand flat palm shape from a long distance to a close distance (Z axis down gesture); and 15B and 15C are relative to the 15A map, detected by the sensing array 112 Schematic diagram of the sensing signal.

In Fig. 15A, the right hand 2 is a flat palm shape at t = t1, that is, the shape of the sensing array 112 facing the palm of the palm relative to the sensing array 112. The right hand 2 is also a flat palm shape when t=tn, but its distance from the sensing array 112 is closer to t=t1.

In FIG. 15B, when t=t1, the sensing array 112 detects the large-area proximity sensing signal 20 generated by the right hand 2, which is the sensing signal generated by the palm tip of the right hand 2 approaching the sensing array 112. .

In FIG. 15C, at t=tn, the sensing array 112 detects the large-area proximity sensing signal 20 generated by the right hand 2, which is the sensing signal generated by the palm tip of the right hand 2 approaching the sensing array 112. .

Looking at the 15A-15C map, it can be found that the right hand 2 is flattened by the palm and gradually moved downward from the distance sensing array 112 to the vicinity of the distance sensing array 112. In this process, the sensing array 112 A large area of proximity sensing signal 20 can be varied. The large-area proximity sensing signal 20 from Fig. 15B and Fig. 15C can be respectively calculated as the palm shape represented by it, that is, the palm shape is flat.

In the central eigenvalue, the flat palm shape of the 15A~15C diagram moves vertically downwards, and it can be easily seen that the two-dimensional central eigenvalue is unchanged, but the three-dimensional central eigenvalue is approximately vertically moved. Therefore, in this embodiment, there is no specific change in the palm shape, but rather a change in the movement of the Z-axis.

In the above embodiments, it can be concluded that the input interface device for controlling the electronic device according to the present invention can calculate the sensing signal generated by the array 112, and calculate the single object representing the palm by the edge feature value or The palm shape of the multi-object, and at the same time, the palm-shaped description of each time is performed by calculating the central feature value of the palm shape. The gesture can be judged by the palm shape change and the change of the central feature value at different times. Therefore, the present invention is primarily required to perform palm shape calculations and judgments. For a variety of different palm-shaped embodiments, please refer to Figure 16.

Figure 16 is an illustration of various palm shapes in an input interface device for controlling an electronic device in accordance with the present invention. The palm-shaped embodiments listed in Fig. 16 are: single point palm shape 501, two point palm shape 502, three point palm shape 503, four point palm shape 504, five point palm shape 505, large palm shape 506, hand palm Shape 507, flat palm shape 508, oblique palm shape 509, grip palm shape 510, single finger palm shape 511, two finger palm shape 512, three finger palm shape 513, four finger palm shape 514, five finger palm shape 515. These palm shapes can be pre-stored in the memory, and the palm shape can be confirmed in a fuzzy comparison manner.

Among them, the single point palm 501 is caused by a single finger, which may be the index finger, thumb, middle finger, ring finger or little finger. The two-point palm shape 502 may be caused by the index finger and the middle finger, the thumb and the middle finger. Large palm shape 506 may be caused by condensation of five fingers, or it may be caused by condensation of two fingers, or it may be caused by condensation of three fingers and four fingers. In addition, the decision of the single point palm shape 501, the two point palm shape 502, the three point palm shape 503, the four point palm shape 504 and the five point palm shape 505 is not the only information of the large area sensing data. Generally speaking, it will contain the sensing data of the hand and wrist parts of the hand, and the sensing amount will be less than this single point to five points, or equal to or less than this single point or five points, and the operator's hand is opposite. At what angle the panel is. The point is that there are distinguishable single or multiple points. In the process of the palm shape decision, the five palms can be obtained by grasping the data of the fist and the wrist as the background.

Among them, the single finger palm shape 511, the two finger palm shape 512, the three finger palm shape 513, the four finger palm shape 514, the five finger palm shape 515 and the single point palm shape 501, the two point palm shape 502, the three point palm shape 503, four The difference between the palm shape 504 and the five point palm shape 505 is that the relative relationship between the finger and the palm is different. For example, the single-finger portion detected by the single-finger palm 511 is relatively small in comparison to the portion of the fist. The single point of the single point 501 detected by the single point 501 is relatively larger than the part of the fist. The difference between the other two palm 502 and the two-finger palm 512, and the difference of the rest are the same, and will not be described again.

In addition, the single-finger palm shape 511, the two-finger palm shape 512, the three-finger palm shape 513, the four-finger palm shape 514 and the five-finger palm shape 515 are not determined by the large-area sensing data. In general, it contains sensing data to the grip and wrist portions of the hand, and the amount of sensing will be greater than the amount of sensing per finger, since the position is closer to the panel than the portion of the finger. In addition, the part of the finger, which belongs to the more parallel, can be seen as the outline of the finger, which is different from the situation of a single point or a multi-point palm. In the process of the palm shape decision, the data of the fist and the wrist are taken together as a palm shape to be considered, and the five palm shapes can be obtained.

Once the palm shape is confirmed, the judgment of the change between the palm shape and the palm shape can be performed. The movement of the palm shape can be determined by means of the central feature value. That is, the central feature value of each palm shape, for example, the center coordinate, is calculated, and then the movement of the center feature value of the palm shape is used as a reference for object movement. The change of the palm shape depends on the change of the palm shape produced by each sampling time.

It should be noted that since the distribution system uses a three-dimensional sensing method, the central characteristic value will have a three-dimensional variation. However, in practice, it is also possible to obtain a two-dimensional gesture change using only two-dimensional changes. Therefore, the change in the central eigenvalue can be performed using only two-dimensional variation values, or three-dimensional variation values. Among them, the three-dimensional change value can be derived from three-dimensional gesture changes. In the following, various gesture changes that can be derived by using the present invention are respectively introduced, namely, an object two-dimensional movement gesture, an object three-dimensional movement gesture, and an object palm shape change gesture.

Therefore, the present invention summarizes three types of basic palm-shaped changes: three-dimensional movement gestures of objects, three-dimensional movement gestures of objects, and gestures of object-shaped changes of gestures. The following are described separately.

Figure 17A is an embodiment of a two-dimensional movement gesture for operating an object in an input interface device for controlling an electronic device in accordance with the present invention. Referring to FIG. 17A, the two-dimensional movement gesture of the operating object is fixed to the palm of the operating object, and the gesture of moving the two-dimensional movement in a fixed palm shape. Therefore, it combines both the fixed palm shape and the two-dimensional movement of the central feature value to make a judgment.

The two-dimensional moving gesture of the operating object includes any combination of the following gestures: a panning gesture 601, a clockwise rotation gesture 602, a counterclockwise rotation gesture 603, a clockwise circle gesture 604, a counterclockwise circle gesture 605, and a clockwise repetition. Round gesture 606, counterclockwise repeat circle gesture 607, delete gesture 608, clockwise corner gesture 609, counterclockwise corner gesture 610, clockwise triangle gesture 611, counterclockwise triangle gesture 612, tick gesture 613, any lap Gesture 614, any double circle gesture 615, square gesture 616, star gesture 617, zoom gesture 618, zoom out gesture 619, custom gesture 620.

Two-dimensional moving gestures can replace traditional two-dimensional touch gestures, and more, provide more gesture commands to electronic systems such as computers and mobile phones for more applications. In other words, the traditional two-dimensional touch gesture is based on the movement of a single or multiple touches to make a gesture determination. In the proximity gesture of the present invention, the real gesture determination is performed according to the real palm shape, and the advantage of detecting the hand motion and then outputting the gesture command without touching is required, which is not possible by the touch gesture.

Figure 17B is an embodiment of a three-dimensional movement gesture for operating an object in an input interface device for controlling an electronic device in accordance with the present invention. Referring to FIG. 17B, the three-dimensional movement gesture of the operating object is attached to the palm shape of the object, and the three-dimensional movement gesture is performed with the fixed palm shape. Therefore, it combines both the fixed palm shape and the three-dimensional movement of the central feature value to make a judgment.

The object three-dimensional movement gesture includes any combination of the following gestures: a vertical pan gesture 701, a vertical clockwise rotation gesture 702, a vertical counterclockwise rotation gesture 703, a vertical clockwise circle gesture 704, a vertical counterclockwise circle gesture 705, and a vertical Clockwise repeating circle gesture 706, vertical counterclockwise repeat circle gesture 707, vertical right hook gesture 708, vertical left hook gesture 709, vertical clockwise corner gesture 710, vertical counterclockwise corner gesture 711, vertical clockwise A triangle gesture 712, a vertical counterclockwise triangle gesture 713, a vertical click gesture 714, a vertical double tap gesture 715, a vertical multi-click gesture 716, a vertical continuous tap gesture 717, and a vertical custom gesture 718-720.

The three-dimensional moving gesture can be applied to different products. For example, in an interactive game software, a variety of different three-dimensional gestures can be used to achieve interaction with the game software. For example, a vertical click gesture can replace a click gesture of a physical touch. For example, a vertical continuous slap gesture can be used as a gesture for simulating drumming. The specific gesture application depends on the designer's thinking about the product.

In addition, the three-dimensional moving gesture has the three-dimensional gesture judgment ability that the traditional two-dimensional touch gesture can not detect at all, and moreover, can provide more meta-gesture instructions to electronic systems such as computers and mobile phones to carry out more Applications.

Figure 17C is an embodiment of a manipulation of a palm shape change gesture in an input interface device for controlling an electronic device in accordance with the present invention. Referring to Figure 17C, the manipulation of the palm-shaped change gesture is based on the palm shape change of the object, and the gesture accompanying the movement of the center feature value of the object. Therefore, it combines the palm shape change, the two-dimensional movement of the center feature value, or the three-dimensional movement to make a judgment.

The object palm shape change gesture includes any combination of the following gestures: a two-point condensation gesture 801, a condensation two-point magnification gesture 802, a three-point condensation gesture 803, a condensation three-point magnification gesture 804, a four-point condensation gesture 805, and a condensation four points. Zoom gesture 806, five-point condensation gesture 807, condensation five-point zoom gesture 808, hand knife turn flat gesture 809, flat hand knife gesture 810, hand knife turn oblique palm gesture 811, oblique palm hand knife gesture 812, five-finger turn fist gesture 813 The fist-turning five-finger gesture 814, the two-finger turning fist gesture 815, the fist-turning two-finger gesture 816, the five-finger turn-to-big gesture 817, the big-point five-finger gesture 818, the five-finger two-finger gesture 819, and the two-finger five-finger gesture 820.

In combination with the gesture embodiment of FIGS. 17A-17C, the input interface device for controlling an electronic device according to the present invention can perform three-dimensional movement gestures of an operation object, a three-dimensional movement gesture of an operation object, and a palm shape change gesture of an operation object. The gestures are integrated to transform a variety of different application gestures. For example, the 15 palm shapes in Fig. 16 can be judged by the two-dimensional moving gesture alone, so at least 15x20=300 kinds of gesture changes. If the re-integrated operation object changes in the palm shape, 15x20x20=6,000 variations can be integrated. Due to the complexity of the changes, you can pick the combination of gestures that you want to apply in the actual design process.

Hereinafter, a specific embodiment will be described to explain the application of the proximity gesture.

Figure 18A is an application of the right hand 2 using a single finger for gesture operations. When the right hand 2 is operated with a single finger, the sensing array 112 detects a large area sensing signal, wherein in the portion of the point, the sensing signal is strong, and therefore, it is determined to be a single point palm 501. When the single point palm 501 is applied to a screen having a plurality of pattern options, or a certain coordinate, if the single point palm 501 is vertically downward, that is, the Z axis is moved downward, That is, when it is judged that it is a vertical downward gesture among the vertical pan gestures 701, the action of the screen option can be performed. For example, the display of the pre-prepared pattern is performed, and the pre-prepared pattern is an enlarged display pattern or a jump-out enlarged pattern with respect to the function option pattern.

As shown in FIG. 18A, the screen option 101 represents an option for the phone, and the screen option 102 represents an option for the gas station, wherein the screen option 101 enters because the right hand 2 performs a vertical downward gesture among the vertical pan gestures 701. The pattern state is pre-prepared, thus magnifying the screen option 101. Thus, the pattern of the screen option 101 is larger than the screen option 102 and is in an enlarged state, making it easier for the user to click. The 18B graph shows the state of the large-area proximity sensing signal 20. When the right hand 2 gradually approaches the sensing array 112, the large-area proximity sensing signal 20 will change in the sensing amount, that is, the central characteristic value will have Z. A change in the axis, which in turn detects a vertical pan gesture.

When the pre-prepared pattern appears on the screen, the user can execute the option of executing the pre-prepared pattern as long as the user performs another confirmation gesture. For example, the confirmation gesture may be: a real touch proximity gesture detection device, a real click proximity gesture detection device, a real combo proximity gesture detection device, or a vertical click gesture 714 and a vertical double click gesture 715 among the proximity gestures. Vertical multi-hitting gesture 716.

Although the present invention has been disclosed above in the foregoing embodiments, it is not intended to limit the invention. It is within the scope of the invention to be modified and modified without departing from the spirit and scope of the invention.
