Magic Finger device suggests new day for calling up content (w/ Video)
(Phys.org)—You can swipe and tap away for content on mobile device screens. What about not having to use the screen? A group from University of Alberta, Toronto and Autodesk Research presented their answer at the ACM Symposium that took place from October 7 to October 12 in Cambridge, Massachusetts. Their Magic Finger is a thimble-like device worn on the user's finger for making gestures to control smart devices like phones or tablets. "If I am walking down the street and the cellphone is in my pocket, I can make a swiping gesture and execute a function like making a call," Tovi Grossman, a scientist at Autodesk Research, told Discovery. Magic Finger is placed on the fingertip using an adjustable Velcro ring. As a demo video shows, commands can be placed on a variety of surfaces for content to be displayed on the screen.
