It's really hard to design products by focus groups. A lot of times, people don't know what they want until you show it to them.

Whittaker, Steve, Matthews, Tara, Cerruti, Julian, Badenes, Hernan and Tang, John (2011): Am I wasting my time organizing email?: a study of email refinding. In: Proceedings of ACM CHI 2011 Conference on Human Factors in Computing Systems 2011. pp. 3449-3458.
We all spend time every day looking for information in our email, yet we know little about this refinding process. Some users expend considerable preparatory effort creating complex folder structures to promote effective refinding. However modern email clients provide alternative opportunistic methods for access, such as search and threading, that promise to reduce the need to manually prepare. To compare these different refinding strategies, we instrumented a modern email client that supports search, folders, tagging and threading. We carried out a field study of 345 long-term users who conducted over 85,000 refinding actions. Our data support opportunistic access. People who create complex folders indeed rely on these for retrieval, but these preparatory behaviors are inefficient and do not improve retrieval success. In contrast, both search and threading promote more effective finding. We present design implications: current search-based clients ignore scrolling, the most prevalent refinding behavior, and threading approaches need to be extended.

Lau, Tessa, Cerruti, Julian, Manzato, Guillermo, Bengualid, Mateo, Bigham, Jeffrey P. and Nichols, Jeffrey (2010): A conversational interface to web automation. In: Proceedings of the 2010 ACM Symposium on User Interface Software and Technology 2010. pp. 229-238.
This paper presents CoCo, a system that automates web tasks on a user's behalf through an interactive conversational interface. Given a short command such as "get road conditions for highway 88," CoCo synthesizes a plan to accomplish the task, executes it on the web, extracts an informative response, and returns the result to the user as a snippet of text. A novel aspect of our approach is that we leverage a repository of previously recorded web scripts and the user's personal web browsing history to determine how to complete each requested task. This paper describes the design and implementation of our system, along with the results of a brief user study that evaluates how likely users are to understand what CoCo does for them.

In: Proceedings of the ACM Symposium on User Interface Software and Technology October 7-10, 2007, Newport, Rhode Island, USA. pp. 139-148.
Webmail clients provide millions of end users with convenient and ubiquitous access to electronic mail -- the most successful collaboration tool ever. Web email clients are also the platform of choice for recent innovations on electronic mail and for integration of related information services into email. In the enterprise, however, webmail applications have been relegated to being a supplemental tool for mail access from home or while on the road. In this paper, we draw on recent research in the area of electronic mail to understand usage models and performance requirements for enterprise email applications. We then present an innovative architecture for a webmail client. By leveraging recent advances in web browser technology, we show that webmail clients can offer performance and responsiveness that rivals a desktop application while still retaining all the advantages of a browser based client.
