Embodiment approach 4
[0136] The difference between the fourth embodiment and the above three methods is that the above three methods locate the input device according to the captured infrared rays, while the implementation method four locates the input device according to the position of the blocked infrared rays. A detailed description.
[0137] The notebook computer of the embodiment of the present invention comprises:
[0138] motherboard;
[0139] a central processing unit arranged on the motherboard;
[0140] A chipset, arranged on the motherboard, connected to the central processing unit;
[0141] a storage device, arranged on the main board, for storing the preset position information and the corresponding relationship between the preset position information and the control signal;
[0142] a light source module, arranged on the main board, for emitting light;
[0143] A camera module, arranged on the main board and connected to the chipset, is used to acquire the image generated by the...

The invention provides an input control device, a notebook computer and an input control method. The device comprises a light source module for emitting first light rays, a camera module for acquiringan image generated by second light rays which are light rays, changed by an input device, among the first light rays, an information extraction module for acquiring first position information on theinput device from the image, a storage module for storing preset position information and a mapping relation between the preset position information and a control signal, a comparison module for comparing the first position information and the preset position and acquiring a comparison result, an output module for outputting a first control signal corresponding to first preset position informationwhen the comparison result shows that the first position information is matched with the first preset position information in the preset position information. The input control device, the notebook computer and the input control method realize the low-cost and simple implementation of touch control and avoid interfering and influencing the vision of users.
Description
technical field [0001] The invention relates to the input technology of electronic equipment, in particular to an input control device, a notebook computer and an input control method. Background technique [0002] With the success of the iPhone in the market, touch control technology has become a hot topic. Touch control can bring users a unique experience, and will be a hot spot in the development of human-computer interaction technology in the future. The next-generation mainstream operating system window7 will fully support touch control technology. [0003] The current touch control technology relies on a special capacitive touch screen, such as a resistive touch technology using a multi-layer circuit film. [0004] At the same time, there is a Frustrated Total Internal Reflection solution, which can support up to 52 points and even recognize shapes. However, this solution requires a special medium (glass), and also requires a special light source and modulation equip...
