Abstract
A digital pen systems and methods are provided. The digital pen comprises an internal pen module comprising a cartridge and a pressure sensor, a body housing the internal pen module, and a shuttle connected to the internal pen module on a first end of the digital pen and connected to a twist mechanism on a second end of the digital pen. The shuttle moves the cartridge and the pressure sensor when the twist mechanism is engaged.
Claims15
A digital pen, comprising:
- an internal pen module comprising a cartridge and a pressure sensor;
- a body housing the internal pen module;
- and
- a shuttle connected to the internal pen module on a first end of the digital pen and connected to a twist mechanism on a second end of the digital pen,
- wherein the shuttle moves the cartridge and the pressure sensor when the twist mechanism is engaged.
A positional input method, comprising:
- detecting, using a detector, at least a part of an optical pattern disposed on a display, the part of the optical pattern corresponding to a location on the display,
- wherein the detector is located in a digital pen, comprising:
- an internal pen module comprising a cartridge and a pressure sensor;
- a shuttle connected to the internal pen module on a first end of the digital pen and connected to a twist mechanism on a second end of the digital pen,
- wherein the shuttle moves the cartridge and the pressure sensor when the twist mechanism is engaged.
A positional input system, comprising:
- a plurality of displays, each of the displays having disposed thereon a respective predetermined optical pattern;
- a processor to determine to which display of the plurality of displays a sensor is proximate;
- and
- a digital pen comprising:
- the sensor to detect a part of the predetermined optical pattern disposed on the display to which the detector is proximate, the part of the predetermined optical pattern corresponding to a location on a surface of the display;
- a transmitter to transmit data representing the location of the digital pen to a computing device communicatively coupled to the digital pen,
- wherein the sensor is located in an internal pen module along with a cartridge, and the cartridge and the pressure sensor are moved when a twist mechanism in the pen is engaged.
The positional input system, wherein the internal pen module stays stable when twist mechanism in the pen is engaged.
