A series of senior-centered design experiments were used to define the best-fitting web hierarchy for health information for seniors are reported.Three experiments were performed, namely card sorting, category identification and category labeling. The ...

This paper reports on some fundamental parameters for the design of wall-based laser pointer interaction techniques. Ten users participated in this study and their laser points were tracked and recorded by a computer. The data collected were then ...

Interactive maps provide unique ways to support collaboration. They can be used to navigate virtual environments and support collaborative activities within these environments. This poster gives an example of map-based navigation and some guidelines for ...

A situation that traditional PC centered computing does not serve well is that of transient workers; workers who are required to move from place to place frequently, yet still be able to interact with their data. We used intra-body signaling to ...

As traditional media make the transition to the web, the need for a systematic way of assessing the entertainment value of interfaces becomes increasingly important. In this paper we describe an experiment using online manipulations of traditional paper ...

Increasingly expressive input and information presentation techniques are said to enhance interactivity. This paper argues that increased interactivity alone is not sufficient. Though in many cases it may allow more flexible or efficient methods for ...

In large-scale systems a user may be required to perform status-monitoring tasks that rely upon the detection of changes among differentially coded icons. We demonstrate a technique for analyzing the utility of coding dimensions in terms of the users' ...

In this paper I introduce the problem of displaying dynamic information. I give several examples where an individual must interact with information that is changing beyond her control. The challenge in displaying this information is to discover how the ...

The emergence of Internet has provided an alternative channel for companies to promote their services and products online besides the traditional medium. An overview of Internet advertising diagram is also outlined in the paper. Banner ads, as the first ...

Personalization, the system knowing about you, can be distinguished from personification, the degree to which the system projects itself as being human. In this experiment personalization is crossed with personification to create four interfaces to a ...

We present the human factors of a (boardroom or home) group videoconference in which a camera is operated via a remote control. We describe a system that automates this camera operation, the rules it uses, and its effect on the quality of a conference ...

We present the Lumitouch system consisting of a pair of interactive picture frames. When one user touches her picture frame, the other picture frame lights up. This touch is translated to light over an Internet connection. We introduce a semi-ambient ...

We observed the same task executed by 49 users on four production web sites. We tracked the rates of discovery of new usability problems on each site and, using that data, estimated the total number of usability problems on each site and the number of ...

In this paper, we describe the "smart headphones" system, which detects and relays speech sounds in the environment through the user's headphones. This allows the user to be aware of speech events and remain involved in conversations while using ...

Findings from the present study show that different strategies for concatenating voice recordings significantly affect subjective preferences and memory of aurally presented information. Specifically, two different automatic telephone number ...

We describe a unified design for voice interaction with simple machines; discuss the motivation for and main features of the approach, include a short sample interaction, and report the results of two preliminary experiments.

This modification of an experimental panel is an attempt to demonstrate the dynamic and impromptu parts of the interaction design process. Teams of designers, usability engineers and project managers will design solutions to interaction problems live on ...

Users are human. As HCI professionals we must be sure that our fellow humans perceive their encounter with usability and design professionals as pleasant without sacrificing the accuracy of our results. There are guidelines produced by professional ...

In this panel, the panelists will take a serious look at the "myths" that are part of the hype surrounding the wireless market and explode those myths to expose the underlying more serious human interface issues that exist.
