All the Information You Need Could Be in Your Pocket

Researchers at the University of Waterloo's Cheriton School of Computer Science in Canada have developed a tool to display basic information from incoming messages to smartphones and other wireless devices by shining it through one’s apparel. The PocketView technology uses light-emitting diode (LED) displays that can serve either as standalone devices or be linked wirelessly to smartphones through Bluetooth. Cheriton's Antony Albert Raj Irudayaraj said the displays show only minimal information, which is "good enough if you're walking or biking, for example, to show basic navigation instruction." Experiments found thin and light-colored fabrics transmit LED light better, while many darker-colored fabrics and denser, patterned weaves are sufficiently transparent to see the lit LEDs underneath, especially indoors.
