AI Technical Summary

Problems solved by technology

However, this way of pointing by infrared laser will be affected by various interferences and affect the pointing effect
For example, if the brightness of the display screen or the surrounding environment is too high, the light spot hit by the infrared laser on the screen will be relatively dark and cannot be easily seen
Moreover, if there is a relatively large angle between the lecturer's speech position and the screen, the light spot of the infrared laser on the screen will be relatively dark, which will also affect the indication effect

Embodiment 1

[0046] Such as figure 1 As shown, this embodiment proposes an interactive method, the method comprising:

[0047] S101. Receive a first instruction sent by a second device;

[0048] S102. Identify the current demonstration scene of the first device;

[0049] S103. When the demonstration scene of the first device is the first scene, generate a second instruction according to the first instruction, and send the second instruction to the first device.

[0050] Specifically, the second device described in this embodiment is a writing device, such as a writing pen. In this embodiment, however, the first device may be a conventional touch device, and the second device can write on the screen of the first device. That is to say, the first device is simply a device that can provide touch for the second device. Users can use the second device to write on the screen of the first device, and embedded in the first device can analyze and calculate the The trajectory of the movement on ...

Embodiment 2

[0062] Such as figure 2 As shown, this embodiment proposes another interactive method, which includes:

[0063] S201. Receive a first instruction sent by a second device;

[0064] S202. Identify the current first device demonstration scene;

[0065] S203. When the demonstration scene of the first device is the second scene, generate a third instruction according to the first instruction, and send the third instruction to the first device.

[0066] Specifically, the interaction method proposed in Embodiment 1 is aimed at the interaction process when the demonstration scene of the first device is the first scene. As mentioned above, the demonstration scene of the first device can also be the second scene, or It is just a simple file selection scene, such as the desktop or folder interface. For this scenario, the lecturer does not need to guide the audience, but the lecturer still needs to give himself an indicator to perform file selection and cursor or pointer movement oper...

Embodiment 3

[0076] Such as image 3 As shown, this embodiment proposes an interaction device, the interaction device includes a processor, and the processor is configured with processor-executable operation instructions to perform the following operations:

[0077] receiving a first instruction sent by the second device;

[0078] Identify the current first device demo scene;

[0079] When the demonstration scene of the first device is the first scene, a second instruction is generated according to the first instruction, and the second instruction is sent to the first device.

[0080] Specifically, the second device described in this embodiment is a writing device, such as a writing pen. In this embodiment, however, the first device may be a conventional touch device, and the second device can write on the screen of the first device. That is to say, the first device is simply a device that can provide touch for the second device. Users can use the second device to write on the screen of...

Abstract

The invention provides an interaction method, which relates to the field of human-computer interaction. The method comprises the following steps: receiving a first instruction sent by a second device;identifying a current first device demonstration scenario; when the first device demonstration scene is a first scene, a second instruction is generated according to the first instruction, and the second instruction is sent to the first device. The invention also provides an interactive device and a system. The invention receives the instruction of the speaker to operate the demonstration device,and then performs differential display in combination with the demonstration scene displayed by the current touch device. Moreover, the remote interaction between the presentation device and the touch device enables the speaker to perform the presentation, so that the speaker can clearly explain the contents of the presentation to the audience. No blurring or blurring of the presentation cursor occurs.

Description

technical field [0001] The present application relates to the field of human-computer interaction, and in particular to an interaction method, device and system. Background technique [0002] Optical imaging electronic whiteboards are mainly used in education and office work, and are very popular with users because of their high interactivity. One of the existing optical imaging touch screen technologies usually includes a camera module, a light source, and a retro-reflective strip. The brightness information is analyzed. Because the light path is blocked by the opaque medium, the angular direction of the blocking object can be identified, and the position of the touching object can be identified. [0003] At present, in the teaching and office process of using the optical image electronic whiteboard, the speaker often explains to other people from a distance. The specific position of the content on the screen. As a result, pens or teaching aids with infrared laser pointer...
