Abstract: The present invention provides a new and useful hybrid digital and physical interactive writing surface. A user writes on a physical writing surface using thermal ink. Underneath the physical writing surface is a heating layer. Once the heating layer is activated, the thermal ink disappears. Meanwhile, sensors capture a user's strokes while writing, and a computing device digitally stores the captured strokes. Therefore, there is zero-time delay or lag time between writing on the physical writing surface and its appearance. Finally, there is no need to erase any writing nor use other sheets or boards after one use because the writing is automatically erased.

Abstract: The present disclosure discloses a method for updating an environmental threshold in touch sensing, a touch sensor, and a water outlet device. The method repeatedly collects a detection value until a difference obtained by comparing the detection value collected at an Nth repetition with a current environmental threshold is greater than a first threshold and a current value of a counter is greater than a second threshold and then updates the detection value collected at the Nth repetition to the current environmental threshold. In this way, the environmental threshold can be dynamically updated according to environmental changes, thereby reducing incorrect operations.
