Making computers easier for older adults to use: area cursors and sticky icons
TLDR
The study described here indicates that when combined, these techniques can decrease target selection times for older adults by as much as 50°/0 when applied to the most difficult cases (smallest selection targets).

Predicting human interruptibility with sensors
TLDR
This article presents a series of studies that quantitatively demonstrate that simple sensors can support the construction of models that estimate human interruptibility as well as people do, and therefore their use in everyday office environments is both practical and affordable.

Examining the robustness of sensor-based statistical models of human interruptibility
TLDR
It is demonstrated that sensor-based statistical models of human interruptibility can provide robust estimates for a variety of office workers in a range of circumstances and can do so with accuracy as good as or better than people.

Feasibility and pragmatics of classifying working memory load with an electroencephalograph
TLDR
An experiment is described to explore some of the issues around using an elec-troencephalograph (EEG) for classifying working memory load, including a novel feature selection scheme that seems to alleviate the need for complex drift modeling and artifact rejection.

Unlocking the expressivity of point lights
TLDR
This paper works through a structured design process that points the way towards a much richer set of expressive forms and more effective communication for small point lights, using thousands of human judgments to measure the suitability of different expressive forms for conveying different information content.
