Abstract: A body-wearable interactive device with a retractable earbud and a microphone provides data, audio and voice communication with a wearable personal computing or other remote device. Full voice and display interface with a personal computer can be achieved with the use of a wireless link between the input/output device and computer. The device is adapted for use with a variety of ancillary communications devices to provide flexibility in field and mobile communications scenarios. Corresponding methods are also disclosed by which a wearer can effect communication through and with the interactive device.

Abstract: A screen peripheral system according to an embodiment of the invention includes a computing device for producing a main image and a touch-activated input device for generating and displaying a composite image visible to a user. The composite image simultaneously includes a representation of at least one key, for example a QWERTY keyboard, for activating an input function, and the main image provided by the computing device. The keyboard representation preferably is laid over the main image. According to one embodiment, the main image is an output image generated by an application being executed by the computing device. Other touch screen systems and methods are also disclosed.
