6 Applications
FreeDigiter is designed to be suitable for various scenarios
where a contact–free control system with simple commands
might be needed. To inform our design, we are experimenting
with two applications that can be controlled by
entering numbers.
The first application, a<b>n MP3 player, plays the track
whose number is entered by moving the appropriate number</b>
of fingers past the proximity sensor. With the trends in
consumer electronics miniaturization, MP3 players of the
near future could be reduced in size so that they consist of
nothing more than an earplug. However, before such a device
becomes practical, a new way to control the player is
needed because they would no longer allow space to placebuttons.
The second application simulates the<b> functions of a mobile
phone and offers a more sophisticated scheme where
commands are linked to numbers. Our prototype application
allows the user to accept a call, speed–dial, or prompt
complete phone numbers w</b>ithout touching the phone or
headset. The phone is simulated on a desktop PC. Since
it is easier to enter small numbers, we chose to split commands
into layered menus. The system starts in its default
mode and offers the following options:
<b>1. answer call (one finger)
- speed-dial (two fingers)
- dial phone number (three fingers)</b>
After selection, the simulation proceeds to an appropirate
submenu. For instance, after having chosen answer
call the user either takes the call (one finger) or has the
computer play a pre-recorded message (two fingers)
that says that the user is currently driving in heavy traffic
but intends to return the call in five minutes.</p>
