To design an easy-to-use interface, pay attention to what users do, not what they say. Self-reported claims are unreliable, as are user speculations about future behavior.

Karrer, Thorsten, Krämer, Jan-Peter, Diehl, Jonathan, Hartmann, Björn and Borchers, Jan (2011): Stacksplorer: call graph navigation helps increasing code maintenance efficiency. In: Proceedings of the 2011 ACM Symposium on User Interface Software and Technology 2011. pp. 217-224.

We present Stacksplorer, a new tool to support source code navigation and comprehension. Stacksplorer computes the call graph of a given piece of code, visualizes relevant parts of it, and allows developers to interactively traverse it. This augments the traditional code editor by offering an additional layer of navigation. Stacksplorer is particularly useful to understand and edit unknown source code because branches of the call graph can be explored and backtracked easily. Visualizing the callers of a method reduces the risk of introducing unintended side effects. In a quantitative study, programmers using Stacksplorer performed three of four software maintenance tasks significantly faster and with higher success rates, and Stacksplorer received a System Usability Scale rating of 85.4 from participants.

Krämer, Jan-Peter (2010): PIM-Mail: consolidating task and email management. In: Proceedings of ACM CHI 2010 Conference on Human Factors in Computing Systems 2010. pp. 4411-4416.

Traditional email clients are built with a "one-touch" model in mind that assumes an immediate action is performed once an email is read. However, some emails require a follow-up action or users decide to read them later, so they cannot be discharged immediately. We present a prototype to keep track of these email-associated tasks that works as a plug-in inside a traditional email client. Besides providing flexible task management features, such as linking more than one message to a task to follow conversations, our system also supports exchanging tasks for collaborative work.

Krämer, Jan-Peter, Karrer, Thorsten, Diehl, Jonathan and Borchers, Jan (2010): Stacksplorer: understanding dynamic program behavior. In: Proceedings of the 2010 ACM Symposium on User Interface Software and Technology 2010. pp. 433-434.

To thoroughly comprehend application behavior, programmers need to understand the interactions of objects at runtime. Today, these interactions are often poorly visualized in common IDEs except during debugging. Stacksplorer allows visualizing and traversing potential call stacks in an application even when it is not running by showing callers and called methods in two columns next to the code editor. The relevant information is gathered from the source code automatically.
