Characterization of the mechanical properties of tactors used in tactile displays
Pancake motors used in a tactile display were analyzed to understand the characteristics of their operation, as well as to suggest improvements in the design of the display. The frequencies and forces produced by unencased and encased pancake motors were measured, and a motor model was formulated …

Ubiquitous interactive displays: magical experiences beyond the screen
Ubiquitous Interactive Displays are interfaces that extend interaction beyond traditional flat screens. This thesis presents a series of proof-of-concept systems exploring three interactive displays: the first part of this thesis explores interactive projective displays, where the use of projected …

A novel binary actuator using shape memory alloy
… world it would be beneficial to have a wearable tactile display that takes advantage of touch to communicate information to the user without causing visual distractions. This thesis presents the design and development of a novel actuator that can be configured into thin, flexible arrays to meet …

The design of personal ambient displays
… is to investigate the design of personal ambient displays. These are small, physical devices worn to display information to a person in a subtle, persistent, and private manner. They can be small enough to be carried in a pocket, worn as a watch, or even adorned like jewelry. In my …

Frequency response of human skin in vivo to mechanical stimulation
… at a scale useful in the development of tactile displays. Sinusoidal vibration stimuli of varying frequencies and amplitudes were applied with a flat-ended 0.5 mm diameter cylindrical probe under two conditions: it was either glued to the skin or not. Both normal and tangential stimlui …

Considerations for the Development of Non-Visual Interfaces for Driving Applications
While haptics, tactile displays, and other topics relating to non-visual user interfaces have been the subject of a variety of research initiatives, little has been done specifically related to those for blind driving. Many automation technologies have been developed for the purpose of assisting …

An Oral Tactile Interface: Design and Development
While tactile displays have been designed for the fingertip and other body locations of relatively larger area, the potential of the oral cavity for housing a tactile interface is largely unexplored. Nevertheless, with hidden, silent, and hand-free operation, an oral tactile interface may provide …

The Design, development, and analysis of a wearable, multi-modal information presentation device to aid astronauts in obstacle avoidance during surface exploration
… surface exploration and way-finding. Multi-modal displays are being considered as cues to multiple sensory modalities enhance cognitive processing through taking advantage of multiple sensory resources, and are believed to communicate risk more efficiently than unimodal cues. This thesis presents …

Mechanical and psychophysical studies of surface wave propagation during vibrotactile stimulation
Vibrotactile displays are based on mechanical stimulation delivered using an array of motors to communicate with the user. The way in which the display's motors are spaced and positioned on the body can have a significant impact on the effectiveness of communication, especially for tactile displays …
