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

Abstract

The invention relates to a telecommunication apparatus (10) having a projection device (11) for projecting image information onto a projection surface located outside the telecommunication apparatus (10), wherein the telecommunication apparatus (10) is configured such that the projection device (11) projects the image information starting from the telecommunication apparatus (10) in different first directions of a projection direction range (20) onto the projection surface, wherein the telecommunication apparatus (10) has an input detection device (12) in addition to the projection device (11), wherein the telecommunication apparatus (10) is further configured such that by means of the input detection device (12) it is possible to detect a user input effected by means of a movement of a body part of a user, wherein the user input takes place starting from the telecommunication apparatus (10) in a detection direction range (30) located outside the projection direction range (20), wherein the user input is non-contact in relation to the telecommunication apparatus (10).

Description

technical field [0001] The invention proceeds from a communication device according to the preamble of claim 1 having a projection device for projecting image information onto a projection surface located outside the communication device. Background technique [0002] Such communication devices are generally known, especially in the form of a communication terminal such as a portable computer or a mobile phone or the like with a projection device. [0003] Such a communication device has the advantage that not only a relatively small display area or display device of the communication device is provided for the display of the image information, but also that the following functionality can be realized especially for situations where a plurality of persons have to jointly observe the displayed image information: The information is projected onto a projection surface located outside the communication device. In the display of images or movies by means of projection devices (h...

Problems solved by technology

[0004] Traditionally, this is achieved in projection devices installed in portable communication devices in that the device, in particular a touch-sensitive surface of the device, or an input device, such as a key device or the like, has to be touched (in particular by the user's finger) etc., however this has the disadvantage of disturbing the projected image, especially by shaking or other negative influences

Furthermore, it is disadvantageous that on especially portable communication devices there is little space for input elements such as control buttons or operating devices, and when using projection devices the device is often not optimally positioned for actuation of the input elements by the user
