Digital and Electronic Device Design Caster Remote Control by Tech4home Caster remote control was designed for use with Telefonica’s Movistar and TV service. Important control elements are the centrally arranged navigation area and the carefully placed symbol for the integrated voice command function that lets the user interact with Aura virtual assistant. On the reverse side of the remote control, a soft coating provides additional comfort and an appropriated grip, which enables particularly secure handling. The most frequently used buttons on the remote control light up when the device is picked up in a dimly lit room.
