Abstract
A touch system and a touch method thereof are provided. A signal receiving apparatus of the touch system receives a first light signal and a pressure sensing signal sent by a touch apparatus. A computing apparatus of the touch system judges a touch position of the touch apparatus according to the first light signal, and decides an expected size of a touch trajectory according to the pressure sensing signal, so as to produce a corresponding touch effect in response to a magnitude of a pressing force, and improve applicability of the touch system.
Claims14
A touch system, comprising:
- a touch apparatus, configured to send an indication signal when a touch region is touched, wherein the indication signal has a first light signal and a pressure sensing signal generated by the touch apparatus by sensing a feedback pressure of the touch region;
- a signal receiving apparatus, configured to receive the first light signal and the pressure sensing signal from the touch apparatus, wherein the signal receiving apparatus comprises an image capturing circuit, and the image capturing circuit is configured to receive the first light signal, and the image capturing circuit generates a coordinate signal according to a touch position of the first light signal on the touch region;
- and
- a computing apparatus, coupled to the signal receiving apparatus, and configured to receive the coordinate signal and the pressure sensing signal from the signal receiving apparatus, and configured to judge the touch position of the touch apparatus according to the coordinate signal, and configured to decide an expected size of a touch trajectory according to the pressure sensing signal.
A touch method of a touch system, comprising:
- providing a signal receiving apparatus, and receiving an indication signal sent by a touch apparatus when the touch apparatus touches a touch region, wherein the indication signal has a first light signal and a pressure sensing signal generated by the touch apparatus by sensing a feedback pressure of the touch region;
- providing an image capturing circuit of the signal receiving apparatus, receiving the first light signal, and generating a coordinate signal according to a touch position of the first light signal on the touch region;
- and
- providing a computing apparatus, receiving the coordinate signal and the pressure sensing signal from the signal receiving apparatus, judging the touch position of the touch apparatus according to the coordinate signal, and deciding an expected size of a touch trajectory according to the pressure sensing signal.
