Projection mobile phone using light induction and pressure induction

Abstract

The invention provides a projection mobile phone using light induction and pressure induction. The projection mobile phone comprises a mobile phone body and an input deice, wherein the mobile phone body comprises a first wireless communication unit, a projection unit, a voice input unit, a voice output unit and a first signal processing unit electrically connected with the units; the projection unit projects an image through light rays comprising a specific light ray; the input device comprises a second wireless communication unit, a light induction unit, a pressure induction unit and a second signal processing unit electrically connected with the units; the light induction unit inducts the specific light ray, produces a position signal according to the specific light ray and sends the position signal to the second signal processing unit; the pressure induction unit generates an input signal according to pressure change and sends the input signal to the second signal processing unit; the second signal processing unit calculates a specific pressing region according to the position signal and produces a key signal according to the specific pressing region and the input signal; and the second wireless communication unit is suitable for communication with the first wireless communication unit. The invention provides the mobile phone with a relatively high user experience.

Description

technical field [0001] The invention relates to a mobile phone, in particular to a projection mobile phone. Background technique [0002] With the rapid development of science and technology, the life of modern people has entered an information age, and timely information communication has become very important. When instant communication is required, people generally choose traditional telephones or use cell phones.
