- Description
- This thesis discusses the design and implementation
of ARMadillo, a simple virtual environment interface in the form of
a small wireless device that is worn on the forearm. Designed to be
portable, intuitive, and low cost, the device tracks the
orientation of the arm with accelerometers, magnetic field sensors,
and gyroscopes, fusing the data with a quaternion based Unscented
Kalman Filter. The orientation estimate is mapped to a virtual
space that is perceived through a tactile display containing an
array of vibrating motors. The controller is driven with an 8051
microcontroller, and includes a BlueTooth module and an extension
slot for CompactFlash cards. The device was designed to be simple
and modular, and can support a variety of interesting applications,
some of which were implemented and will be discussed. These fall
into two main classes. The first is a set of artistic applications,
represented by a suite of virtual musical instruments that can be
played with arm movements and felt through the tactile display, The
second class involves utilitarian applications, including a custom
Braille-like system called Arm Braille, and tactile guidance. A
wearable Braille display intended to be used for reading
navigational signs and text messages was tested on two
sight-impaired subjects who were able to recognize Braille
characters reliably after 25 minutes of training, and read words by
the end of an hour.
