Tablets and styluses are practical and purposeful, but as companies continue to explore gesture-controlled technology, something like this motion-sensing ring will be the way of the future. It is a simple device masked like a piece of jewelry that allows people to execute such actions are controlling buttons and writing in the air. In this and more, the motion-sensing ring can be likened to Leap Motion and Sixense STEM.
In order to detect writing in the air accurately, Fujitsu's motion-sensing ring "relies on software that detects 'unwanted connections' (the parts where you'd normally be lifting your pen from the paper) and only tracks the remaining data," according to The Verge. Although it is still unknown just how accurate this software is, the motion-sensing ring is a more compact and lightweight version of similar products.
