Abstract

Usual the RCU (Remote Control Unit) design features big buttons, limited size, and less functions or features. Hence, the RCU display size is always limited so that it is either small and only dichromatic or nonexistent. However, the RCU is able to do more than just an RCU. Additional features such as video playback, internet access, and user friendly control can be achieved by an additional LASER (Light Amplification by Stimulated Emission of Radiation) projector integrated in the RCU as it is depicted in Figure 1. The LASER projector is able to project a display screen on close or far objects like the user's hand (see Figure 2). That way the size of the projected picture depends on the distance between the RCU projector and the projected area.

Usual the RCU (Remote Control Unit) design features big buttons, limited size, and less functions or features. Hence, the RCU display size is always limited so that it is either small and only dichromatic or nonexistent. However, the RCU is able to do more than just an RCU. Additional features such as video playback, internet access, and user friendly control can be achieved by an additional LASER (Light Amplification by Stimulated Emission of Radiation) projector integrated in the RCU as it is depicted in Figure 1. The LASER projector is able to project a display screen on close or far objects like the user’s hand (see Figure 2). That way the size of the projected picture depends on the distance between the RCU projector and the projected area.

With this special feature integrated in an RCU, other features can be implemented to an RCU like a radio tuner, Internet access, video playing, etc. that need a larger screen. These features can be controlled by the user via the RCU. The range of features is not limited by the size of the display anymore.

In addition, the RCU do not require a proper screen. The projector can be used in nearly every environment. There are no special surfaces or special lighting conditions necessary. The LASER projector does not require zoom or focus settings. The user has just to press the on button and a clear projected image can...
