Method for interacting by adopting optical indicator, optical indicator as well as presentation method and system

Abstract

The embodiment of the invention relates to a method for interacting with equipment by utilizing an optical indicator, the optical indicator as well as a presentation method and system adopting the optical indicator. The method for interacting comprises the following steps of: detecting a light spot generated by the optical indicator; determining a sequence of the state of the light spot in a preset time interval according to the detection result; and determining an interaction event according to the sequence of the light spot so as to interact with the equipment. According to the embodiment of the invention, more than one light spot is utilized, and the light spot is mapped to different interaction events according to the sequence of the state of the light spot in the preset time interval, thus more interaction events can be presented. The light spot is easier and simpler to detect, and a detection method can be used for improving the accuracy and the reliability of detection, thus the sequence of the state of the light spot can be mapped into a mouse event and a corresponding mouse signal is generated, so that interaction with a computer is realized.

Description

technical field [0001] Embodiments of the present invention relate to the field of optical indication interaction, and in particular to an optical indicator, a method for interacting with a device using an optical indicator, and a display method and system for using an optical indicator. Background technique [0002] Displays such as projection screens used in conferences are becoming increasingly important for displaying information for everyday use at work or in life. But in some applications, traditional interaction methods are not convenient. Especially in large display environments, traditional desktop input devices such as computer mice and keyboards are not suitable for direct manipulation or control of on-screen objects. For example, due to the need for interaction, a traditional computer using a keyboard and mouse will restrict the speaker to the location of the computer, which is inconvenient. In such cases, some method of remote interaction is required, especial...
