Description of Related Art
Wireless enabled devices, i.e. electric devices having a WiFi capability and being able to establish a wireless link to other devices to receive and/or transmit data or any kind of information, are nowadays in widespread use. Such wireless enabled devices include, but are not limited to, mobile phones, smart phones, tablet computers, PDAs, photo cameras, video cameras, portable music or video players, TV-sets, disc players, personal computers (PCs) or gaming devices. Examples for disc players are DVD players or Blu-ray players. Examples for personal computers (PCs) are desktop computers, notebook computers, netbooks or so-called ultra-books. Examples for gaming devices are video game consoles or handheld/portable game consoles. Some wireless enabled devices (including some of those mentioned before) can be used as mobile devices.
權利要求
The invention claimed is:1.

The mobile device as claimed in claim 1 , wherein said display is configured to display an image acquired of the surrounding of the mobile device and to indicate wireless enabled devices detected within said image. 3. The mobile device as claimed in claim 1 , wherein said display is configured to continuously display currently acquired live video and to indicate wireless devices detected within the currently displayed live video. 4. The mobile device as claimed in claim 1 , wherein said processor is configured to analyze an image, in particular by image segmentation, identify devices in an analyzed image and to identify wireless enabled devices among the identified devices. 5. The mobile device as claimed in claim 1 , wherein said user interface comprises a touch screen that is integrated in said display and that is configured to enable a user to select an indicated wireless enabled device shown on said touch screen. 6. The mobile device as claimed in claim 1 , wherein said camera is configured to acquire still images and/or live video images and comprises a still camera, a video camera, an image sensor or an image sensor module. 7. The mobile device as claimed in claim 1 , wherein said display is configured to indicate a detected wireless enabled device by an indicator that is configured to indicate if a detected wireless enabled device is ready for establishing a wireless link with said wireless interface. 8. The mobile device as claimed in claim 1 , wherein the mobile device is configured to check the availability and/or wireless link capability of a wireless link to a detected wireless enabled device before said display indicates a detected wireless enabled device by an indicator that is configured to indicate if a detected wireless enabled device is ready for establishing a wireless link with said wireless interface. 9. The mobile device as claimed in claim 1 , wherein said display is configured to display an availability indicator to indicate if a detected wireless device is configured to perform a pre-selected task after establishing a wireless link with said wireless interface. 10. The mobile device as claimed in claim 1 , wherein said display is configured to display a completion indicator to indicate if a pre-selected task by use of a wireless link has been completed. 11. The mobile device as claimed in claim 1 , wherein said display is configured to display a guidance signifier that is configured to guide a user of the mobile device to hold the mobile device in the direction of a selected wireless enabled device. 12. The mobile device as claimed in claim 1 , further comprising an orientation sensor that detects the orientation of the handheld mobile device. 13. The mobile device as claimed in claim 1 , wherein said wireless interface is configured to transmit probing signals and receive response signals from wireless enabled devices to identify said wireless enabled devices, the capabilities of devices including a wireless enabled device and/or one or more parameters of said wireless enabled devices. 14. The mobile device as claimed in claim 1 , wherein said wireless interface is configured to receive a beacon signal transmitted by a wireless device, said beacon signal including one or more parameters of a detected wireless enabled device. 15. The mobile device as claimed in claim 1 , wherein said processor is configured to detect an optical information signal transmitted by a wireless enabled device, said optical information signal indicating that the wireless enabled device has a wireless link functionality and/or including one or more parameters of a detected wireless enabled device. 16. The mobile device as claimed in claim 1 , wherein said processor is configured to detect an optical information signal transmitted by a light source, in particular an LED or an IP diode, or a predetermined display image displayed on a screen of a wireless enabled device. 17.
