In this paper we propose an architecture for rendering rich and
high-resolution haptic feedback on the user’s body while playing
interactive games. The haptic architecture consists of three main
elements, namely, haptic engine, haptic API/codec, and haptic
display. The haptic engine extracts events from the game, assigns
haptic feedback to these events, and sends coded packets to
haptic API/codec. The haptic API/codec translates the coded
packets and computes driving signals based on carefully
evaluated algorithms derived from psychophysical modeling of
tactile perception. The driving signals are then routed to the
haptic display embedded with an array of vibratory transducers. A
user feels high resolution and refined tactile sensations on the
body through the display. We have integrated the Surround
Haptics system with a driving simulation game to provide an
enjoyable gaming experience.

BodiPod: Interacting with 3D Human Anatomy
via a 360° Cylindrical Display i321a

We present BodiPod, a 3D 360 degree stereoscopic human
anatomy browser. Our cylindrical display allows users to view a
human anatomy volume at full scale from any perspective. Shutter
glasses are only required if users want to examine the data
stereoscopically. Users can change views simply by walking around
the display volume, and interact with the human anatomy model
inside the display through gesture and speech interactions, which
include scaling, rotation, peeling, slicing and labeling. Our
demonstration shows that using a cylindrical display has the
benefits of providing stereoscopic rendering of human anatomy
models at life-size scale that can be examined from any angle,
while allowing interactions from an appropriate viewing distance.

Exertion Games involve physical effort and as a result can facilitate
physical health benefits. We present Hanging off a Bar, an action
hero-inspired Exertion Game in which players hang off an exercise
bar over a virtual river for as long as possible. Initial observations
from three events with audiences ranging from the general public
to expert game designers suggest that Hanging off a Bar can be
engaging for players and facilitate intense exertion within
seconds. Furthermore, we collected suggestions for what game
elements players believe could entice them to increase their
physical effort investment. These suggestions, combined with
Hanging off a Bar as research vehicle due to the easy
measurement of exertion through hanging time, enable future
explorations into the relationship between digital game elements
and physical exertion, guiding designers on how to support
exertion in digital games.

Vignette is an interactive system that facilitates texture creation in
pen-and-ink illustrations. Unlike existing systems, Vignette
preserves illustrators’ workflow and style: users draw a fraction of a
texture and use gestures to automatically fill regions with the
texture. We currently support both 1D and 2D synthesis with
stitching. Our system also has interactive refinement and editing
capabilities to provide a higher level texture control, which helps
artists achieve their desired vision. A user study with professional
artists shows that Vignette makes the process of illustration more
enjoyable and that first time users can create rich textures from
scratch within minutes.
