Embodiment Construction

[0081] The present invention includes two parts, the handheld terminal 10 and the host receiving terminal 13 .

[0082] like figure 1 and figure 2 As shown, the handheld terminal includes a power control lock 1, a status indicator light 1, a three-dimensional mouse function start key 3, a cursor start and alignment key 4, a writing key 7, a function key A8, a function key B5, a function key C9, and a function key D6 , circuit board 15 and power supply module 16. The host receiving end includes a USB interface 12 , a circuit board 17 and a status indicator light 11 .

[0083] Wherein the USB interface 12 of the host receiving end can be inserted into the USB interface cavity 14 of the handheld end, so that the handheld end 10 and the host receiving end 13 are buckled together. When the host receiver 13 is on the handheld terminal 10, the power control lock 1 is in the pressed state, and the power of the interactive pen is cut off; Pass.

Abstract

The invention discloses a remote interactive pen and a handwriting detection method. The remote interactive pen comprises a handheld end and a receiving end. The handheld end detects a writing motion characteristic quantity of a penholder by adopting a three-axis gyroscope and two three-axis accelerometers and measures the relative motion distance between the penholder and a screen or the ground by adopting ultrasonic distance measurement; and the measurement information is subjected to data fusion according to a human writing motion model, solution of the writing motion characteristic quantity and identification of writing intention so as to realize handwriting detection. The receiving end is used for receiving writing control information solved by the handheld end, handwriting information and three-dimensional motion information of a cursor. Through the application of tracking and positioning arm motion characteristics to control cursor motion, operate a window and realize distance writing function, increasing the motion detection function vertical to the projection screen direction, serving as a three-dimensional air mouse for virtual reality and the like, the remote interactive pen overcomes the defect that the conventional input equipment cannot reflect the three-dimensional motion information of the cursor, and has the characteristics of simple structure and convenient use.

Description

technical field [0001] The invention relates to a computer input device, in particular to a remote interactive pen and a handwriting detection method. Background technique [0002] In activities such as press conferences, product exhibitions, lectures, and lectures, projectors are used more and more frequently and are irreplaceable. Yet there is a big shortcoming when using projector at present, can not operate the system flexibly exactly. Some companies have launched electronic whiteboards based on the principle of electronic induction for multimedia projection applications, using the electromagnetic induction between the whiteboard and the stylus to realize the positioning of the stylus, so that users can perform operations such as writing circles on the whiteboard like ordinary blackboards , but when the user writes on the whiteboard, it is easy to block the light of the projector projected from behind, and it is impossible to write at a long distance. [0003] In the p...
