Touch device with function switch control, system with the touch device, and method for controlling function switch of the touch device

A touch device with function switch control, comprising:

• a touch unit having multiple traces aligned in a first-axis direction and a second-axis direction;
• a scan unit electrically connected to the touch unit, connected to the traces in the first-axis direction and the second-axis direction to acquire sensing information corresponding to an object on the touch unit, and built in with a function switch control method, wherein the function switch control method has steps of:
• determining if the object on the touch device is a preset object;
• determining if the sensing information of the preset object meets a function-switching condition according to a variation of the sensing information of the preset object;
• and
• generating a switch-on signal if the function-switching condition is met.

A touch system with function switch control, comprising:

• a capacitive stylus having:
• a main body;
• a sensing portion mounted on the main body;
• and
• a nib portion being retractable and mounted on one end of the main body and having a tip adjusted to vary a distance to the sensing portion;
• and
• a touch unit having multiple traces aligned in a first-axis direction and a second-axis direction;
• a scan unit electrically connected to the touch unit, connected to the traces in the first-axis direction and the second-axis direction to scan sensing information on the touch unit, and built in with a function switch control method, wherein the function switch control method has steps of:
• determining if an object on the touch device is a preset object;
• determining if the sensing information meets a function-switching condition according to a sensing information variation of the preset object;
• and
• generating a switch-on signal if the function-switching condition is met.
