The present disclosure relates to a method and a system for remote collaboration, the method includes: receiving mouse operation information of a user in the master computer which is captured and transmitted by the master computer; detecting a position of the mouse cursor on the master split screen in accordance with the mouse operation information, then when the cursor arrives at a boundary of the master split screen and continues to move in a direction away from the master split screen, detecting a current split screen connecting to the boundary, and displaying the cursor on the current split screen; and receiving interaction information transmitted by the master computer, and transferring the interaction information to a current slave computer corresponding to the current split screen, so as to cause the current slave computer to execute the interaction information, where the interaction information is the information which is obtained and intercepted by the master computer when the master computer detects interaction initiated by the user with the master computer. The present disclosure can realize the collaboration function in wireless screen transmission based on the display of multiple sources on the same screen, thus rendering the operations convenient.

A pointing system including: a pointing device including an operation portion and a light-emitting portion that emits light according to an operation to the operation portion; and a control device including an image pickup portion that picks up light from the light-emitting portion when the light-emitting portion emits light and outputs an image including information on a light spot of the light, a display portion that includes a screen and displays a pointer on the screen, and a control portion that judges, as well as judge a movement of the light spot based on the information on the light spot in the image and move the pointer on the screen based on the movement of the light spot, whether the light spot is turned off based on the information on the light spot in the image and executes processing related to a click when the light spot is turned off.

An electronic device includes a display unit, a touch panel, and a controller. The display unit displays a pointer that points out an input location. The touch panel detects a touch operation on the display unit with one of a user's finger and a pointing device. The controller controls a display location of the pointer on the display unit and performs an input process in accordance with the touch operation on the touch panel. Moreover, the display unit displays a predetermined region for use in designating, as the display location of the pointer, a location different from a location of the touch operation. When the controller detects a continuous touch operation from an inside to an outside of the predetermined region, the controller moves the pointer at a location different from a touch location in the continuous touch operation, in accordance with movement of the touch location.

This is directed to adjusting the size of displayed text in response to receiving user instructions. An electronic device can display text or other content using one or more default sizes. A user can direct the device to increase a display size of text by providing a corresponding input. In response to receiving the instruction, the electronic device can increase the display size of the text and display the beginning of the text (e.g., the beginning of a sentence), even though an input may be detected in a region near the end of the text. In some cases, when the user instructs the device to increase the display size of text beyond a maximum level, the electronic device can provide an audio output corresponding to the text instead of or in addition to increasing the display size of the text.

A method, a device, and a system are provided for recognizing a gesture based on multi-terminal collaboration, which are used to recognize an air gesture operation of a user in a multi-terminal collaboration scenario. The method includes receiving, by a first terminal after receiving a collaboration request activation signal, parameter information of second terminals; recording, by the first terminal according to the parameter information of the second terminals, an arrangement manner of terminals that participate in acquiring of gesture information, where the terminals that participate in the acquiring of the gesture information include all terminals or the second terminals; receiving, by the first terminal, sensor trigger information sent by at least one second terminal; and determining, by the first terminal according to the recorded arrangement manner and the acquired sensor trigger information, a type of a gesture that triggers a sensor.

The present disclosure provides a method, a video system, and a system for realizing a simple air mouse. The method includes: a video terminal obtaining current position parameters of an air mouse, wherein the current position parameters comprise a deflection angle and a deflection direction of the air mouse with respect to an originally-calibrated coordinate position; and determining a position of a cursor on the video terminal according to the current position parameters and a preset scale parameter. By presetting reference points in the air mouse, the present disclosure obtains the deflection angle and the deflection direction of the air mouse with respect to the original position by the camera device based on the above reference points, and determines the position of the cursor on the video terminal according to the deflection angle and the deflection direction and the preset scale parameter.
