TOUCHSCREEN WRITING SYSTEM |
摘要 |
A touchscreen writing system includes a shaft having on-screen circuitry configured to communicate with an electronic display in an on-screen condition, and off-screen circuitry configured to communicate with the electronic display in an off-screen condition. A stylus controller sends signals to a touch-sensitive interface of the electronic display for determining a coarse approximate position for the writing nib. The stylus controller also determines relative fine approximate position coordinates for the writing nib, which are sent to the computing device. A touch-sensitive interface controller provides a starting reference point for fine positioning of the writing nib based on a last coarse approximate position as determined by the on-screen circuitry for the off-screen condition. The stylus controller sends fine positioning information to the touch-sensitive interface and a detector determines whether the writing nib has been engaged on an off-screen writing surface.
