Abstract
A digital pen with tracking and pressure-sensitive functions comprises a pen core with a tracking module in the digital pen. The tracking module is used for detecting the pen core shifted in a direction with an optical signal. A pressure-sensitive module is connected with the pen core, which is used for detecting the pen core under a pressure and shifted relatively to the digital pen, and converting the pressure into an electric signal.
Claims18
A digital pen with tracking and pressure-sensitive functions, said digital pen comprising:
- a pen core with a tracking module in said digital pen, said tracking module for detecting said pen core shifted in a direction with an optical signal;
- and
- a pressure-sensitive module connected with said pen core, said pressure-sensitive module for detecting said pen core that is under a pressure and is shifted relatively to said digital pen and converting said pressure into an electric signal.
A digital pen capable of handwriting input, said digital pen comprising:
- a pen core in said digital pen, said pen core capable of being under an inputted pressure thereby is shifted relatively to said digital pen;
- a tracking in said pen core for detecting said pen core shifted in a direction through an optical signal;
- and
- a pressure-sensitive module connected with said pen core for applying a deformation corresponding to said inputted pressure and converting said deformation into an electric signal.
A digital pen capable of handwriting input, said digital pen comprising:
- a pen core in said digital pen, said pen core capable of being under an inputted pressure thereby is shifted relatively to said digital pen;
- a tracking in said pen core for detecting said pen core shifted in a direction through an optical signal, said tracking module comprising:
- a light source for emitting an incident light beam onto a touch pad in said direction, said touch pad enabling said incident light beam to be reflected as a reflective light beam;
- a photosensitive device having a photosensitive area for accepting said reflective light beam;
- and
- a reflector for conducting said reflective light beam to enter vertically into said photosensitive area;
- and
- a pressure-sensitive module connected with said pen core for applying a deformation corresponding to said inputted pressure and converting said deformation into an electric signal.
