SkinTrack can turn your skin into a touchscreen
Smartwatches are often criticised for their fiddly, hard to control interfaces. Now, a lab at Carnegie Mellon University has found a solution – a device that means the wearer’s skin can be used as the touchscreen. The Future Interfaces Group, part of the university, have created ‘SkinTrack’, which “enabled continuous tracking on the skin”. A ring, worn on the non-watch hand, emits a “high frequency AC signal” that connect to a sensing wristband, much like the strap of a traditional smartwatch, which is fitted with electrodes. When the ring finger touches the watch-wearing hand, a signal is sent to the watch and allows wearers to navigate their device using their skin. A number of commands are also possible - you can sign documents, for example, and tracing particular letters will bring up particular apps, for example (‘E’ for email or ‘F’ for Facebook).
