TEMPORA

Intelligent Interruption Management using ElectroDermal Activity
 EDA     UbiComp     Analytics 

With limited time and attentional resources, analysts are faced with a constant stream of new information that might be important, yet disrupting. Timing interruptions based on an analyst's state of arousal (signifcantly increasing, decreasing, at random intervals or none) as detected by GSR was tested. Analysts performed and rated team experience significantly better when interruptions occurred during increasing arousal than at random. Significant arousal increase was also found to be associated with "aha" moments.

REFLECTIVA

Sensemaking Translucence through Self Awareness to reduce Bias
 InfoViz     CMC     Analytics 

Collaborative sensemaking is endangered by prematurely focusing on non-optimal solution due to biases. Reflectiva makes analysts more aware of their sensemaking processes and focus of attention. In empirical testing, users performed far better with REFLECTIVA than without, yet rated it lower in user experience. However, it raises concerns about balancing task performance vs. UX in critical analytics.

RAMPARTS

Supporting Sensemaking with Colocated Mobile Interactions
 Adhoc/Mobile     Ubicomp     Analytics 

To overcome small screen space for information display in ad-hoc sensemaking sessions with mobile devices, RAMPARTS offers a spatially-aware system to connect multiple displays to act as one big display. RAMPARTS significantly decreased task completion time compared to paper, without affecting cognitive load or task completion time adversely compared to an interactive tabletop, as tested empirically.

SAVANT

Supporting Sensemaking & Analytics for Remote Collaborations
 Implicit Sharing     CMC     Analytics 

When analysts collaborate to solve problems, they need to share insights to connect info, identify patterns, and find solution. SAVANT is a collaborative analysis tool that implicitly shares insights and notes, without needing explicit information push/request, offering better task performance than explicit sharing. SAVANT also showed that each compoenent should be evaluated for costs/benefits

Crowds4Sense

Supporting Semsemaking through Crowd-Sourcing
 Crowdsourcing     CMC     Analytics 

Crime solving is a domain where solution discovery is often serendipitous. Unstructured mechanisms, like Reddit, for crime solving through crowds have failed so far. Non-experts, while lacking formal training, might instead offer non-conventional perspectives that should be explored further to better understand the cost vs. benefits to involving crowds in sensemaking tasks.

Culture/Web Design

Cultural effects on Self-Presentation of Govt. Websites
 Culture     Design 

This work goes beyond the relevance of Hall and Hofstede's works to the web design in traditional domain areas like e-commerce, by exploring how those differences can be seen in the government website design across BRIC, and US. We describe our findings confirming that differences exist, more so between China and US in the homepage layout and use of design elements.

SPRING

Speech & Pronunciation Improvement using Games
 ICTD     Games 

Lack of proper English pronunciations is a major problem for immigrant population, even in developed world, creating a barrier to entry into mainstream society. SPRING explores the use of speech technologies merged with activity-based and arcade-based games to provide pronunciation feedback for Hispanic children showing significant gains in pronunciation quality.
