The ongoing rise of human computation as a means of solving computational problems has created an environment where human workers are often regarded as nameless, faceless computational resources. Some people have begun to think of online tasks as a "remote person call". In this paper, we summarize ethical and practical labor issues surrounding online labor, and offer a set of guidelines for designing and using online labor in ways that support more positive relationships between workers and requesters, so that both can gain the most benefit from the interaction.

As an input device, fabric holds potential benefits for three dimensional (3D) interaction in the domain of surface design, which includes designing objects from clothing to metalwork. To investigate these benefits, we conducted an exploratory study of different users' natural interactions with fabric. During this study, we instructed users to communicate various shapes and surfaces of varying complexity. A prevailing way of communicating shapes proved to be an in-the-air sketch metaphor. Based on this result, we proposed and implemented a system supporting three in-the-air sketch-based input devices: a point, a flexible curve, and a flexible surface. A preliminary feasibility study found that users successfully sketched objects and scenes despite the influence of tracking issues, suggesting lessons learned and relevant constraints for such systems in future work.

In this work, we discuss a set of metrics for analyzing human spatial behavior (proxemics) motivated by work in the social sciences. Specifically, we investigate individual, attentional, interpersonal, and physiologic...

Event sequence analysis is an important task in many domains: medical researchers may study the patterns of transfers within the hospital for quality control;transportation experts may study accident response logs to identify best practices. In many cases they deal with thousands of records. While previous research has focused on searching and browsing, overview tasks are often overlooked. We introduce a novel interactive visual overview of event sequences called LifeFlow. LifeFlow is scalable, can summarize all possible sequences, and represents the temporal spacing of the events within sequences. In this video, we show an example of patient transfer data and briefly demonstrate how to analyze them with LifeFlow. Please see [11] or visit http://***/hcil/lifeflowformoredetail.
The intertwining of everyday life and computation, along with a new generation of inexpensive digital recording devices and storage facilities, is revolutionizing our ability to collect and analyze human activity data...

This paper presents an empirical study on problems encountered by users with dyslexia when using websites. The study was performed by a user evaluation of 16 websites by a panel of 13 participants with dyslexia, each participant evaluating 10 websites. The results presented in the paper are based on 693 instances of accessibility and usability problems. Most frequent problems were related to navigation issues, problems with presentation and organisation of information, lack or misfunctioning of specific funtionality in websites, and issues with language.
