Abstract

The invention discloses an implementation method of a laser projection keyboard. The method is characterized by including: detecting light reflecting signals generated when fingers tap a projected virtual keyboard area; judging whether the lasting time of the light reflecting signals is in a preset value range or not; if so, identifying the position information of positions tapped by the fingers according to the light reflecting signals so as to identify corresponding input. In addition, the invention further discloses the laser projection keyboard. By the implementation method and the laser projection keyboard, when the fingers are placed on the key area of the keyboard for a rest when keyboard input is not performed, mistaken identification of the laser keyboard is avoided, and the situation that other areas cannot be used to perform input is avoided.

Description

technical field [0001] The invention relates to the field of virtual keyboards, in particular to a laser projection keyboard and a realization method thereof. Background technique [0002] With the popularization of devices such as mobile phones and tablet computers, projection keyboards have attracted more and more attention as a portable and novel input device. However, current projection keyboards leave much to be desired. For example, in the current projection keyboard, the infrared rays emitted by it cannot be completely close to the projected keyboard, so the user's fingers must be suspended in the air, otherwise the infrared rays will be blocked and it will be judged to be inputting characters. However, when we use a physical keyboard, our fingers often rest on the keyboard so that we don’t need to reposition each time. If the fingers are suspended above the keyboard, it is basically impossible to perform touch typing, which greatly reduces the user’s typing speed; ...
