The needs of individuals with limited mobility have not been given as much importance as those of other users of internet-accessible mobile devices. Disabled users have information and service needs that are unique and a timely delivery of these services and information can be invaluable. This has motivated us toward the development of VTAssist, an(More)
When a person visits a place, it is almost always simple to understand the physical environment around them. Often people ignore---or don't have access to---the fourth dimension: time. Our research is an attempt to create a system that adds the aspect of time into location-based notification systems. This allows a person to not only experience their(More)
Finding resources in an indoor facility can be a difficult task, especially for patrons who are not familiar with what the facility has to offer. Current methods of indoor navigation involve the use of static maps, directions posted on walls and other traditional systems. However, as we see greater mobility of always-connected computing devices, we believe(More)
With an ever-increasing dominance of the Internet as the conduit for social, commercial, governance, and research activity; determining the physical location of end points is critical. Physical location is an essential piece of context that informs decision-systems of numerous geo-derived dimensions. For example, the location of a user performing an(More)
Device-assisted navigation is rapidly becoming a major topic in computer science. PDAs and other small devices are enabling the introduction of navigational assistants to many different spaces. These areas are generally filled with points of interest with which users may choose to interact with. The natural behavior of users in such a space is to explore,(More)
Andrea Kavanaugh As spatial awareness technologies grow increasingly accurate and ubiquitous, the need for appropriate human-computer interfaces emerges. This paper summarizes our ongoing work in balancing the attention demanded from users with the utility provided through added reaction and comprehension. In so doing, we describe and discuss three(More)
An emerging challenge in the design of interfaces for mobile devices is the appropriate use of information about the location of the user. This chapter considers tradeoffs in privacy, computing power, memory capacity, and wireless signal availability that accompany the obtaining and use of location information and other contextual information in the design(More)
