Patent Images
1. A touch system comprising:
- a touch device havinga control unit;
a touch interface having multiple touch electrodes electrically connecting to the control unit; and
a wireless communication unit electrically connecting to the control unit; and
an input device havinga body having a contact end;
a controller mounted in the body;
at least one electrode unit mounted in the body and electrically connecting to the controller; and
a wireless communication unit mounted in the body and electrically connecting to the controller;
wherein when the input device receives an uplink signal sent by the touch device, the controller of the input device sends a downlink signal through the electrode unit and the touch electrode of the touch device receives the downlink signal;
wherein the wireless communication unit of the input device sends a side information and the wireless communication unit of the touch device receives the side information;
wherein the uplink signal includes a time stamp indicating a sent time, and the side information includes the time stamp corresponding to the received uplink signal.

Abstract
A touch system includes a touch device and an input device. The uplink signal transmitted by the touch device includes a timestamp. The input device transmits a downlink signal through the electrode unit and transmits a side information through a wireless communication unit. The inclusion of the corresponding timestamp in the side information ensures that the side information is combined with the corresponding downlink signal to correctly present the user'"'"'s operation.
