Abstract

The invention provides a projection input system. The system is operated in wearable equipment which is installed with a transmission device, a projection device and a sensor, wherein the wearable equipment is worn on the wrist of a user. The system comprises a transmission module, a projection module, a determination module and an execution module, wherein the transmission module is used for transmitting infrared rays through the transmission device; the infrared rays form an infrared plane above the hand surface of the user; the projection module is used for projecting a virtual keyboard onto the hand surface through the projection device; the determination module is used for sensing the infrared ray reflected by a finger through the sensor when the user operates the virtual keyboard on the hand surface by using the finger, so as to determinate the operation, carried out by the user, on the virtual keyboard; and the execution module is used for executing a function corresponding to the operation, carried out by the user, on the virtual keyboard. The invention furthermore provides a projection input method. Through the projection input system and method, the users can rapidly and correctly input data and commands to the wearable equipment.

Description

technical field [0001] The invention relates to a projection input system and method. Background technique [0002] With the emergence of wearable devices such as smart bracelets and smart watches, the problem of how to input data and commands to wearable devices has followed. The current mainstream is to input data and commands through voice recognition, but the accuracy of voice input is unstable due to problems such as pronunciation and network. Contents of the invention [0003] In view of the above, it is necessary to provide a projection input system and method, which can more accurately input data and commands to wearable devices. [0004] A projection input system, running in a wearable device equipped with a transmitting device, a projecting device and a sensor, the wearable device is worn on a user's wrist, the system includes: a transmitting module, configured to emit infrared rays through the transmitting device , the infrared rays form an infrared plane abov...
