FLOATING TOUCH METHOD AND TOUCH DEVICE
First Claim
1. A floating touch method used with a capacitive touch panel, comprising steps of:
- controlling the capacitive touch panel to sense a control object within different sensing ranges at different time points to determine a distance value between the control object and the capacitive touch panel;
controlling the capacitive touch panel to detect a floating touch action of the control object based on the distance value; and
issuing a control signal corresponding to the floating touch action.

Abstract
A floating touch method and a touch device are provided. The touch device includes a capacitive touch panel and a sensor circuit. At first, the sensor circuit controls the capacitive touch panel to sense a control object within different sensing ranges at different time points to determine a distance value between the control object and the capacitive touch panel. Then, the sensor circuit controls the capacitive touch panel to detect a floating touch action of the control object based on the distance value. Subsequently, the sensor circuit issues a control signal corresponding to the floating touch action to enable the touch device or the capacitive touch panel to perform a specific function.
