Abstract

A touch control system suitable for contact control and suspension control includes a contact detection device, a suspension detection device and a processing unit. The contact detection device is used for detecting contact control information. The suspension detecting device is used for detecting suspension control information. The processing unit is coupled to the contact detection device and the suspension detection device, and the processing unit is configured to enable the suspension detection device when the contact control information indicates a preset multi-finger gesture.

Description

technical field [0001] The invention relates to a touch control system, in particular to a touch control system suitable for touch control and suspension control and an operation method thereof. Background technique [0002] In the touch operation, the user can relatively control the application program executed by the display device by touching the touch surface and moving a finger on the touch surface. However, in some cases, if the user has to touch the touch surface to perform operations, it will cause inconvenience. For example, when a display device with a large screen is used, it is preferable to be able to control the display device at a certain distance from the display device. [0003] E.g figure 1 It shows a touchless user interface for a mobile device disclosed in US Patent Publication No. 2008 / 0100572, wherein in order to be applicable to different portable devices, the use The operator interface provides the sensing device 200 as an accessory. The sensing d...
