Gauntlet Gab
From: Technology Review - August 2005 - page 31

Using hand gestures to communicate instructions to troops on the battlefield
may seem as antiquated as arm signaling on the highway, but it's reliable and
convenient and therefore remains an integral part of troop interaction.
RallyPoint in Cambridge, MA, has given the practice a high-tech update in the
form of a computerized glove that reads a soldier's hand signals and relays
them wirelessly to troops and commanding officers who may be out of the line
of sight. The glove incorporates various sensors that measure how fingers
bend and touch and detect the direction and speed of hand movements.  

A microprocessor translates the sensor readings into commands - "fall back,"
for instance - which can then be sent to other soldiers over radio equipment
and conveyed as symbols on helmet-mounted view screens or as verbal commands
via an earpiece. RallyPoint is waiting to hear if it will receive its next
round of funding for the project from the army.
