Abstract
With recent developments in visual interface technologies, which are now capable of delivering
rich and highly immersive experiences, the need has arisen to develop equally capable haptic-
feedback technologies that can complement and be easily integrated with their visual counterparts
to enable fully immersive, multimodal, interactive experiences. Moreover, with touchscreen
devices rapidly replacing physical controls, as in the case of automobiles and industrial
equipment, there has been a loss of natural haptic cues and an increased need for operators to
divert their attention from the task at hand into the touchscreen just to find the locations of different
controls – which previously they could feel by relying on haptic cues without having to employ the
visual sense. This is especially concerning for drivers, where even a brief loss of attention could
lead to catastrophic consequences. This work aims to begin addressing these problems by
presenting an approach – based on air-vortex-ring, free-space haptics – that enables existing
visual interfaces to be augmented with haptic feedback capabilities. After presenting our goals
and motivations for this work, the latest approaches to haptic feedback interaction, and a
discussion of the advantages and limitations of each approach, we describe the toroidal air-vortex
approach to free-space haptics in full detail. We then present a multimodal interactive interface
system that we built based on that approach, named
AirTap,
which is the main focus of this thesis.
AirTap is an open-source system that uses 16 air-vortex-ring generators to deliver targeted,
localized, unambiguous, free-space haptic feedback onto a user’s hand when interacting with 3D
virtual objects on a stereoscopic display. We show how AirTap can serve as a multimodal
interactive interface, as a research tool for studying air-vortex-ring based haptics, and as an open
platform for creative expressions. Finally, we provide an extensive discussion of how our system
can be extended beyond its present form and adopted for automotive and other applications.
