Telecommunication unit having a projection device and method for operating a telecommunication unit having a projection device

A telecommunication unit including a projection device to project an image information onto a projection area located outside the telecommunication unit, the telecommunication unit being configured in such a way that the projection device projects the image information, starting from the telecommunication unit into a projection direction range onto the projection area, the telecommunication unit having an input detection device next to the projection device and being further configured in such a way that, using the input detection device, a user input, undertaken using a movement of a body part of a user is detectable, the telecommunication unit being provided so that the user input takes place, starting from the telecommunication unit in a detection direction range that is located outside the projection direction range, the user input being made in a contactless manner with respect to the telecommunication unit.

A method for operating a telecommunication terminal unit, having a projection device for projecting an image information onto a projection area located outside the telecommunication unit, using the projection device, the image information being projected, starting from the telecommunication unit into a projection direction range onto the projection area, the method comprising:

• detecting, using an input detection device of the telecommunication device next to the projection device, a user input, the detecting including detecting a movement of a body part of a user, the telecommunication unit in a detection direction range that is located outside the projection direction range, the user input being made in a contactless manner with respect to the telecommunication unit.
