AHNE: A Novel Interface for Spatial Interaction i425
Matti Niinimäki, Koray Tahiroglu, Aalto University, Finland
In this paper we describe AHNE (Audio-Haptic Navigation
Environment). It is a three-dimensional user interface (3D UI) for
manipulating virtual sound objects with natural gestures in a real
environment. AHNE uses real-time motion tracking and custommade
glove controllers as input devices, and auditory and haptic
feedback as the output. We present the underlying system and a
possible use for the interface as a musical controller.

FlexCam – Using Thin-film Flexible OLED Color
Prints as a Camera Array i434
Connor Dickie, Nicholas Fellion, Roel Vertegaal, Queen’s
University, Canada
FlexCam is a novel compound camera platform that explores
interactions with color photographic prints using thinfilm flexible
color displays. FlexCam augments a thinfilm color Flexible Organic
Light Emitting Diode (FOLED) photographic viewfinder display
with an array of lenses at the back. Our prototype allows for the
photograph to act as a camera, exploiting flexibility of the
viewfinder as a means to dynamically re-configure images
captured by the photograph. FlexCam’s flexible camera array has
altered optical characteristics when flexed, allowing users to
dynamically expand and contract the camera’s field of view (FOV).
Integrated bend sensors measure the amount of flexion in the
display. The degree of flexion is used as input to software, which
dynamically stitches images from the camera array and adjusts
viewfinder size to reflect the virtual camera’s FOV. Our prototype
envisions the use of photographs as cameras in one aggregate
flexible, thin-film device.
Toolset to explore visual motion designs in a
video game i435

Interactive Arts and Technology, Canada
We describe a research toolset to explore visual designs in a video
game. We focus specifically on visual motion, defined by attributes
of motion, and their effect on accessibility, which may lead to a
diminished experience for novice players. Eight expert game
designers evaluated the tool embedded into a simple point and
click game. Specifically they controlled attributes of speed, size of
game elements, and amount of elements on screen associated to
game targets, distractions, and feedback. The tool allowed
experts to define difficulty settings and expose patterns, which
they verified. As a game, we then investigated the effect of visual
motion on accessibility in a formal user study comprised of 105
participants. As a follow-up to this work, we expanded the toolset
to include 8 additional attributes of motion.
