Grips and Gestures on a Multi-Touch Pen (2010)

This work explores the interaction possibilities enabled
when the barrel of a digital pen is augmented with a multitouch
sensor. We present a novel multi-touch pen (MTPen)
prototype and discuss its alternate uses beyond those of a
standard stylus, such as allowing new touch gestures to be
performed using the index finger or thumb and detecting
how users grip the device as a mechanism for mode switching.
We also discuss the hardware and software implementation
challenges in realizing our prototype, and showcase
how one can combine different grips (tripod, relaxed tripod,
sketch, wrap) and gestures (swipe and double tap) to enable
new interaction techniques with the MTPen in a prototype
drawing application. One specific aim is the elimination of
some of the comfort problems associated with existing auxiliary
controls on digital pens. Mechanical controls such as
barrel buttons and barrel scroll wheels work best in only a
few specific hand grips and pen rotations. Comparatively,
our gestures can be successfully and comfortably performed
regardless of the rotation of the pen or how the user
grips it, offering greater flexibility in use. We describe a
formal evaluation comparing MTPen gestures against the
use of a barrel button for mode switching. This study shows
that both swipe and double tap gestures are comparable in
performance to commonly employed barrel buttons without
its disadvantages.
