Abstract
The invention relates to an opto-electronic input device (), wherein the input is formed by detected movements of an object (M), which opto-electronic input device is provided with an optical module () comprising at least one laser () mounted on a carrier plate (), which laser emits a radiation beam (S) that is guided to a plate (V) close to the object (M) and, after reflection therefrom, causes a change in the resonant cavity of the laser () which is representative of the movement of the object (M), and which is measured within the module (). According to the invention, the plate (V) close to the object (M) comprises, within a projection of the object (M), a first portion (VI) through which the beam (S) can pass and which has a fixed position with respect to the carrier plate (), and a second portion (V) which is movable in a direction perpendicular to the carrier plate () and which comprises signal means which, when they are moved, provide a signal that is observable by a user of the device (). In this way, the device () provides feedback to a human user through his tactile sense and preferably also through his auditory sense. The invention also comprises a method of manufacturing such a device and a method of inputting the movement of an object (M) using such a device.
