Glove Lets You Write in Thin Air

A fingerless bike glove equipped with electrical sensors lets you write on thin air, according to new research.

The modified glove could not only allow for discreet, one-handed text messaging but also create an early warning system for neurodegenerative diseases like Parkinson's.

"Handwriting consists of memory, knowledge, cognition and dexterity, and all these processes are simultaneously at work," said Michael Linderman, a neuroscientist and a co-author of the article published in the journal Public Library of Science One (PLoS).

"This process is very sensitive to the general state of the nervous system," and could help to identify potential neurodegenerative diseases earlier than existing techniques.

The researchers started with a fingerless bike glove and 17 electrically sensitive patches.
