Necklace projectors will throw emails onto the floor
Not ready to don a Google Glass headset? An alternative way to access smartphone content could hang around your neck.
A digital device disguised as a necklace or brooch could one day project email, tweets and text alerts onto nearby surfaces, allowing you to open them with hand gestures.
"The projector gives you a window into the virtual world that you carry around like a flashlight, as a way of serendipitously accessing information," says Christian Winkler at the University of Ulm in Germany. His team's Ambient Mobile Pervasive Display generates a green "SMS" graphic that is projected ahead of the user (see video above). To find out who the message is from, you hold your palm in front of you and the sender's name is projected onto it. To read the message, you make a gesture, such as a subtle swipe, and the text is displayed on your hand.
