Description
Technological advances in the past decade alone are calling for modifications to the usability of various devices. Physical human interaction is becoming a popular method to communicate with user interfaces. This ranges from touch-based devices such as an iPad or tablet to free space gesture systems such as the Microsoft Kinect. With the rise in popularity of these types of devices comes the increased amount of them in public areas. Public areas frequently use walk-up-and-use displays, which give many people the opportunity to interact with them. Walk-up-and-use displays are intended to be simple enough that any individual, regardless of experience using similar technology, will be able to successfully maneuver the system. While this should be easy enough for the people using it, it is a more complicated task for the designers who are in charge of creating an interface simple enough to use while also accomplishing the tasks it was built to complete. A serious issue that I'll be addressing in this thesis is how a system designer knows what gestures to program the interface to successfully respond to. Gesture elicitation is one widely used method to discover common, intuitive, gestures that can be used with public walk-up-and-use interactive displays. In this paper, I present a study to extract common intuitive gestures for various tasks, an analysis of the responses, and suggestions for future designs of interactive, public, walk-up-and use interactions.

Description
The burden of adaptation has been a major limiting factor in the adoption rates of new wearable assistive technologies. This burden has created a necessity for the exploration and combination of two key concepts in the development of upcoming wearables: anticipation and invisibility. The combination of these two topics has created the field of Anticipatory and Invisible Interfaces (AII)
In this dissertation, a novel framework is introduced for the development of anticipatory devices that augment the proprioceptive system in individuals with neurodegenerative disorders in a seamless way that scaffolds off of existing cognitive feedback models. The framework suggests three main categories of consideration in the development of devices which are anticipatory and invisible:
• Idiosyncratic Design: How do can a design encapsulate the unique characteristics of the individual in the design of assistive aids?
• Adaptation to Intrapersonal Variations: As individuals progress through the various stages of a disability
eurological disorder, how can the technology adapt thresholds for feedback over time to address these shifts in ability?
• Context Aware Invisibility: How can the mechanisms of interaction be modified in order to reduce cognitive load?
The concepts proposed in this framework can be generalized to a broad range of domains; however, there are two primary applications for this work: rehabilitation and assistive aids. In preliminary studies, the framework is applied in the areas of Parkinsonian freezing of gait anticipation and the anticipation of body non-compliance during rehabilitative exercise.
