We report on a study (N=36) of user preferences for balancing awareness with privacy. Participants defined permissions for sharing of location, availability, calendar information and instant messaging (IM) activity within an application called mySpace. MySpace is an interactive visualization of the physical workplace that provides dynamic information about(More)
In this study 24 participants drove a simulator while listening to three types of messages in both synthesized speech and recorded human speech. The messages consisted of short navigation messages, medium length (approximately 100 words) email messages, and longer news stories (approximately 200 words). After each message the participant was presented with(More)
<Because it is impractical to record human voice for ever-changing dynamic content such as email messages and news, many commercial speech applications use human speech for fixed prompts and synthetic speech (TTS) for the dynamic content. However, this mixing approach may not be optimal from a consistency perspective. A 2-condition between-group experiment(More)
This paper reports on a four-week study of the usage of myTeam, a prototype that provides availability awareness for distributed work groups through the use of sensor data. Automatically detected information such as presence or absence in office, network connection, mouse and keyboard activity is conveyed along with optional user-added information such as "(More)
Elevated p53 expression is associated with several kidney diseases including diabetic nephropathy (DN). However, the mechanisms are unclear. We report that expression levels of transforming growth factor-β1 (TGF-β), p53, and microRNA-192 (miR-192) are increased in the renal cortex of diabetic mice, and this is associated with enhanced glomerular expansion(More)
A study was conducted with 78 subjects to evaluate the comprehensibility of synthetic speech for various tasks ranging from short, simple e-mail messages to longer news articles on mostly obscure topics. Comprehension accuracy for each subject was measured for synthetic speech and for recorded human speech. Half the subjects were allowed to take notes while(More)
This paper reports on a user trial (N=17) that compares the use of two systems for accessing email messages on a telephone handset. The first system uses graphic output and telephone keypad input, while the second system has both graphic and speech output, with keypad and speech as input. To our knowledge, this trial represents the first evaluation of a(More)
