Embodiment 1

[0033] When the size value of the light spot is greater than the first preset size value and smaller than the second preset size value, it is determined that the target object corresponding to the light spot is the second target object or the light spot belongs to the second operator;

[0034] When the size value of the light spot is larger than the second preset size value, it is determined that the target object corresponding to the light spot is a third target object or the light spot belongs to a third operator.

[0035] According to the above preset corresponding relationship, after identifying the size value of each light spot, it can be determined whether each light spot belongs to the first target object, the second target object or the third target object according to the size value of each light spot and the above preset corresponding relationship. The target object, or belongs to the first operator, the second operator, and the third operator, so as to realize the co...

[0054] When the brightness value of the light spot is greater than the first preset brightness value and smaller than the second preset brightness value, it is determined that the target object corresponding to the light spot is the second target object or the light spot belongs to the second operator;

[0055] When the brightness value of the light spot is greater than the second preset brightness value, it is determined that the target object corresponding to the light spot is a third target object or the light spot belongs to a third operator.

[0056] According to the above preset corresponding relationship, after identifying the brightness value of each light spot, it can be determined whether each light spot is the first target, the second target or the third target according to the brightness value of each light spot and the above preset corresponding relationship Objects, or the first operator, the second operator, and the third operator, so as to realize the differenti...

Embodiment 3

[0070] When the wavelength value of the light spot is equal to the second preset wavelength value, it is determined that the target object corresponding to the light spot is the second target object or the light spot belongs to the second operator;

[0071] When the wavelength value of the light spot is equal to the third preset wavelength value, it is determined that the target object corresponding to the light spot is the third target object or the light spot belongs to the third operator.

[0072] According to the above preset corresponding relationship, after identifying the wavelength value corresponding to each light spot, it can be determined whether each light spot is the first target object, the second target object or the second target object according to the wavelength value corresponding to each light spot and the above preset corresponding relationship. Three objects, or the first operator, the second operator, or the third operator, so as to realize the operation ...

Abstract

The invention relates to a method and a device for identifying a multi-objective object of an interactive input device. The method and the device preset corresponding relations between preset parameters of light spots and objects, identify the preset parameters of all the light spots on the interactive input device, and determine the objects corresponding to the light spots according to the preset parameters and the corresponding relations. The method adopts the proposal that the method identifies corresponding parameters (including shape, size and brightness of various light spots, wavelength corresponding to light beams giving out the various light spots, etc.) of the various light spots on the interactive input device, can identify different parameters according to detailed requirements, subsequently determines combinations of the corresponding parameters of the various light spots according to the preset mode, and determines the objects corresponding to the light spots according to the combinations and the preset corresponding relations, so as to realize identification of the different objects, be convenient for distinguished control of operation of the objects, restrictive conditions during movement and operation of various different objects, and be favorable for application and promotion of the interactive input device.

Description

technical field [0001] The invention relates to the technical field of intelligent input of interactive input devices, in particular to a method and device for identifying multiple targets by interactive input devices. Background technique [0002] With the continuous advancement of interactive input device technology, there are more and more ways to realize multi-touch in interactive input devices, and the applications are becoming more and more extensive. Operations such as lines and clicking buttons, and for another example, multiple people can touch on the same touch screen to realize the operation of the computer screen. [0003] For example, the Chinese invention patent with the patent number ZL200410077389.6 and the title of the invention "Photoelectric Positioning Device and Calibration Method for Interactive Electronic Writing Display System" discloses a photoelectric positioning device for electronic writing system and its calibration method. The method comprises...
