Abstract

Disclosed is a device enabling a user to interact with a computer system via a display screen, said device comprising a housing that accommodates electronic circuitry and has a bottom face, where a device display faces said display screen when the device is positioned on the display screen on its bottom face, said device display being configured to display a code optically in two dimensions towards said display screen. The device is characterized by comprising a sensor configured to read a first code from an object in proximity of the device and to provide a sensor signal conveying the first code; and a processing unit coupled to the sensor to receive the sensor signal. The processing unit is coupled to the device display and is configured to convert the first code to a second code and to provide a display signal to the device display to display the second code optically.
