The invention relates to an opto-electronic input device ( 10 ), wherein the input is formed by detected movements of an object (M), which opto-electronic input device is provided with an optical module ( 11 ) comprising at least one laser ( 1 ) mounted on a carrier plate ( 4 ), 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 ( 1 ) which is representative of the movement of the object (M), and which is measured within the module ( 11 ). 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 ( 4 ), and a second portion (V 2 ) which is movable in a direction perpendicular to the carrier plate ( 4 ) and which comprises signal means which, when they are moved, provide a signal that is observable by a user of the device ( 10 ). In this way, the device ( 10 ) 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.
