Problems solved by technology

On the one hand, if the image displayed on the screen is magnified or reduced by using multi-touch, the operation cannot be completed for the physically handicapped. However, the main interface of the system, the video display interface, and the game display interface cannot be enlarged or reduced; on the other hand, if the image displayed on the screen is enlarged or reduced by adjusting the screen resolution, due to the adjustment of the screen resolution Need to manually select and set, so the operation is inconvenient and the user experience is poor

Embodiment 1

[0052] The embodiment of the present invention provides an interactive method, such as figure 1 shown, including:

[0053] S101. The interaction device obtains the position of the visual center and the distance between the human eye and the screen, wherein the visual center is the central point of the visual field of the human eye on the screen.

[0054] In the embodiment of the present invention, the "field of view" of the human eye is defined as the spatial range that the human eye can see when the human eye fixes on one point; The center point of the eye's field of view in the plane viewed by the human eye.

[0055] Exemplarily, the interaction device provided by the embodiment of the present invention has the function of displaying and enlarging or reducing the display interface. When the human eyes watch the image displayed on the screen of the interaction device, the interaction device can calculate the human vision by detecting the distance. The position of the center...

Embodiment 2

[0063] The embodiment of the present invention provides an interactive method, such as figure 2 shown, including:

[0064] S201. The interaction device transmits a first detection signal to human eyes.

[0065] Exemplarily, the interaction device may transmit the first detection signal to the human eye, so that the human eye reflects back the second detection signal corresponding to the first detection signal after receiving the first detection signal.

[0066] Further, the existing eye tracking technology refers to tracking the eye movement by measuring the gaze point of the eyes or the movement of the eye relative to the head. There are many methods of eye movement tracking currently in use, among which the most commonly used non-invasive method is to obtain the position of the eye through video shooting equipment; invasive methods include embedding eye movement measurement coils in the eyes or using microelectrodes to trace eye movements Electrogram.

[0067] Further, t...

Embodiment 3

[0117] Such as Figure 7 As shown, the embodiment of the present invention provides an interaction device 1, including:

[0118] The processor 12 is used to obtain the position of the visual center and the distance between the human eye and the screen 13, wherein the visual center is the central point of the visual field of the human eye in the screen 13, and the visual center The position of the center is sent to the memory 14, and if the distance between the human eyes and the screen 13 decreases, the image displayed on the screen 13 is amplified with the position of the visual center as the center point. As the distance between the eye and the screen 13 increases, the image displayed on the screen 13 will be reduced with the position of the visual center as the center point.

[0119] The memory 14 is used for storing the position of the visual center.

[0120] The screen 13 is used to display images.

[0121] It should be noted that the "field of view" of the human eye i...

Abstract

The embodiment of the invention provides an interaction method and device, and relates to the field of communications. According to the interaction method and device, an image displayed by a screen can be automatically zoomed in or zoomed out according to the change of the distance between human eyes and the screen. The interaction method comprises the steps that the position of an optic center and the distance between the human eyes and the screen are obtained, wherein the optic center is the central point of a visual field of the human eyes in the screen; if the distance between the human eyes and the screen is shortened, the image displayed by the screen is zoomed in with the position of the optic center being the central point; if the distance between the human eyes and the screen is prolonged, the image displayed by the screen is zoomed out with the position of the optic center being the central point.

Description

technical field [0001] The present invention relates to the communication field, in particular to an interaction method and device. Background technique [0002] With the popularity of electronic products such as computers and mobile phones, and the continuous improvement of people's living standards, people need to obtain more information from electronic products in their lives. Therefore, more and more people pay more attention to the convenience of using electronic products. . [0003] In the prior art, people usually use multi-touch or adjust the resolution of the screen to enlarge or reduce the image displayed on the screen. On the one hand, if the image displayed on the screen is enlarged or reduced by using multi-touch, the operation cannot be completed for the physically handicapped; at the same time, the image display interface can only be enlarged by using multi-touch However, the main interface of the system, the video display interface, and the game display int...
