Document Type and Number:
WIPO Patent Application WO/2019/075933
Kind Code:
A1
Abstract:
Disclosed is a method for a single optical component to obtain a pressure-sensitive feedback by achieving a variation in luminous flux. When a button portion is pressed down, a dimming region of a dimming panel gradually decreases, and a dimming region area S4 of the dimming region varies. A light transmitted through the corresponding dimming panel varies, the light being emitted by a light-emitting element, and the luminous flux Φ in such a case also varies correspondingly. Due to the movement of the dimming region, the luminous flux Φ obtained by means of a light-receiving element varies. Further, a pressing real-time position H is obtained by calculating the varied luminous flux Φ, and a pressing gravity and a pressing position can be calculated according to the real-time position H to further obtain any stage of a pressure-sensitive feedback. According to the present application, the pressing gravity and the pressing position can be obtained only by using a single optical component; any stage of the pressure-sensitive feedback can be achieved; and a pressure-sensitive operation can be further correspondingly implemented through simulation. The method in the present application uses an easily installed and assembled structure, is low in production cost, obtains a timely and sensitive pressing feedback when in use, has a long service life and is less prone to be worn down.
