Description
Technical field
The utility model relates to the apparatus for writing of touch-screen, particularly a kind of wireless blackboard eraser device that is used for touch-screen.
Background technology
Along with the development of large scale touch display screen technology, the operation that the user not only can touch in the above can also be carried out operations such as hand-written, drawing in the above.At present, the apparatus for writing that is used for touch system generally has demonstration pen, blackboard eraser, lettering pen etc., and these equipment all are based on the inductive pick-up of touch system.Therefore, on a touchscreen system, respond to a plurality of equipment (lettering pen and blackboard eraser etc.) simultaneously, thereby need enter blackboard eraser pattern or write mode by the size judgement of contact area on the algorithm computation screen.There are a lot of touching techniques all to be based on the single-point touches technology in the prior art, and along with the issue by Windows 7 systems of Microsoft exploitation, solved the bottleneck that multiple point touching, multiple spot are write, traditional blackboard eraser based on the single-point touches technology can not satisfy the demand that the touching technique lifting brings simultaneously.
Traditional blackboard eraser based on the single-point touches technology is to rely on counting of contacting with touch-screen to judge the blackboard eraser state, just system judges it is pen state when having only a point on the touch-screen, the user can write on touch-screen, system is judged to be blackboard eraser in the time of plural, the operation that this moment, the user can only wipe.Because being based at 2, traditional blackboard eraser judges the blackboard eraser state, when the user when writing, if coat-sleeve or other objects are run into touch-screen, just become the blackboard eraser state, perhaps in writing process, nib is oblique excessively, and system also can be judged to be blackboard eraser, finally cause maloperation, brought inconvenience to the user.In addition, though there is wireless technology to realize the blackboard eraser function at present, most structure is need press switch could activate this function, not only lacks the serviceable life of battery, and to the operation that the user makes troubles, does not meet user's use habit.
Therefore, blackboard eraser ubiquity of the prior art following defective: (1) traditional blackboard eraser is based at 2 and judges the blackboard eraser state, when the user when writing, be subjected to external influence easily and cause becoming the blackboard eraser function, maloperation frequency height; (2) existing blackboard eraser is not suitable for the operation based on the touch screen of multiple point touching; (3) existing blackboard eraser need be provided with switch, and need press switch and could activate the blackboard eraser function, has unhandy defective.
