Using Mobile Phones To Write Messages In Air 65
Anonymous writes "Engineering
students at Duke University have taken advantage of the accelerometers
in emerging cell phones to create an application that permits users to
write short notes in the air with their phone, and have that note
automatically sent to an e-mail address. The 'PhonePoint Pen' can be held just
like a pen, and words can be written on an imaginary whiteboard.
With this application a user could take a picture with a phone camera, and annotating it immediately with
a short caption. Duke Computer Engineering Professor Romit Roy
Choudhury said that his research group is envisioning mobile phones as
just not a communication device, but a much broader platform for social sensing and human-computer interaction. Such interactivity has also emerged in the work of other research groups, such as MIT's Sixth Sense project, Dartmouth's MetroSense project, and Microsoft Research's NeriCell project, to name a few."
