Summary Hypothesis Given the two main problems with current system approaches for identifying emotions that limit their applicability: they can be invasive and can require costly equipment, the authors present a solution to determine user emotion by analyzing the rhythm of their typing patterns on a standard keyboard. Contents There have been various methods of evaluating emotional activities that have seen varying rates of success, but they still exhibit one or both of two main problems preventing wide- scale use: they can be intrusive to the user, and can require specialized equipment that is expensive and not found in typical home or office environments. This system using key strokes is more intuitive, unobtrusive and has a w...

Summary Hypothesis This paper hypothesize that people organize their social worlds based on life ‘modes’, i.e., family, work and social. People strategically use communication technologies to manage intimacy levels within these modes, and levels of permeability through the boundaries between these modes.It also emphasizes strong need for focused sharing – the ability to share content only with appropriate audiences within certain areas of life. Contents The paper explores how to leverage natural models of social organization from people’s lives to improve their experiences of social media streams. The performed design research project examines how people might best a) organize their online content, b) transition between...

Ladner - Computer Science & Engineering, DUB Group University of Washington, Seattle, WA 98195 USA Presentation :CHI 2011, May 7–12, 2011, Vancouver, BC, Canada Summary Hypothesis The paper suggests that the blind people have different gesture preferences than sighted people, including preferences for edge-based gestures and gestures that involve tapping virtual keys on a keyboard. They hypothesize differences in the speed, size, and shape of gestures performed by blind people versus those performed by sighted people. Contents Accessible touch screens still present challenges to both users and designers. Users must be able to learn new touch screen applications quickly and effectively, while designers must be able to implement accessible touch screen interaction techniques for a diverse range of devices and application...

Summary Hypothesis The paper hypothesizes that u nder various levels of environmental demands on attention, gestures can offer significant performance gains and reduced attentional load, while performing as well as soft buttons when the user‟s attention is focused on the phone. Furthermore, they propose that the speed and accuracy of bezel gestures will not be significantly affected by environment, and some gestures could be articulated eyes-free, with one hand. Contents The authors examine four factors: moding technique(hard button, soft button and bezel based), gesture type(mark based and free form), user‟s motor activity(sitting and walking), and distraction l...

Authors then present a human-robot system as a proof-of-concept that uses real-time cognitive state information as input and adapts in response. They hypothesize that the prototype system serves as ...

Reference Authors: Kenton O’Hara, Abigail Sellen, Richard Harper Affiliations : Microsoft Research, 7 J J Thomson Avenue Cambridge, UK Presentation: CHI 2011, May 7–12, 2011, Vancouver, BC, Canada Summary Hypothesis The paper highlights the importance of considering the body in BCI and not simply what is going on in the head. They hypothesize that people use bodily actions to facilitate control of brain activity but also to make their actions and intentions visible to, and interpretable by, others playing and watching the game and hence allows those action to be socially organised, understood and coordinated with others and through which social relationships can be played out. Contents The paper discusses findings from a real world study of a BCI-controlled game played as a social activity in the home. This study draws on the philosophical and analytic concerns found in CSCW where techniques for analysing the social in all its embodied forms are well developed. For...
