WE HAVE al­ways been awed by the idea of a screen that is any­where but on a de­vice. Tech­nol­o­gists at Carnegie Mel­lon Univer­sity have obliged us by com­ing out with a pro­to­type smart­watch that pro­jects a screen on the wearer’s arm.

The chunky watch, named Lu­miWatch, dis­plays a 6.2-inch dis­play on the wearer’s fore­arm. This is a fully func­tional screen that re­sponds to scroll, swipe and touch. The idea is to have a stand­alone de­vice, quite apart from a smart­phone, which will have much more screen space than an or­di­nary smart­watch.

The Lu­miWatch has a de­cent port­fo­lio of specs and can work quite smoothly. But there is a prob­lem yet to be solved: the dis­play is not crys­tal clear be­cause it is on the skin and on a sur­face that is rounded. It is bright enough to be vis­i­ble out­side but has lim­ited colours.
