Processing method, device and system for displaying indication marks

Abstract

Provided are a processing method, apparatus and system for displaying an indicator. The method comprises: obtaining a current scenario image comprising a mobile terminal held by a hand, the hand and an image presentation region; determining, according to the current scenario image, an indication direction in which the mobile terminal points to the image presentation region; determining, according to the indication direction and a range of the image presentation region in the current scenario image, an association position of a region which is between the indication direction and the image presentation region and is located in the image presentation region; and displaying an indicator in the associated position according to a display signal provided by the mobile terminal. By using the method, a user can make an indication in an image presentation region at any time by using any mobile terminal; the method has good generality and is convenient to operate, thereby bringing convenience to work and study of the user.

Description

technical field [0001] Embodiments of the present invention relate to the field of electronic information technology, and in particular, to a processing method, device and system for displaying indication marks. Background technique [0002] In today's conference scenes, projectors and projection screens are the most commonly used means of information display. When participants explain and discuss based on the information displayed on the projection screen, they often display laser dots on the projection screen with a laser pointer. Indicate the projected content. However, in some conference scenarios, laser pointers are often neglected or limited in number, which causes a lot of inconvenience. Therefore, if mobile terminals that people can carry on a daily basis, such as mobile phones and PDAs (Personal Digital Assistants, personal digital assistants), have similar laser pointers The indication function will greatly facilitate people's work. [0003] In order to make the ...
