Using a smartphone touchscreen to control apps mirrored to a distant display is hard, since the user cannot see where she is touching while looking at the distant screen. Tactile landmarks at the back of the phone can mitigate this problem, especially in landscape mode [3]: By moving a finger ...

Tangible objects on capacitive multi-touch surfaces are usually only detected while the user is touching them. When the user lets go of such a tangible, the system cannot distinguish whether the user just released the tangible, or picked it up and removed it from the surface. We introduce PERCs, persistent ...

Using a smartphone for touch input to control apps and games mirrored to a distant screen is difficult, as the user cannot see where she is touching while looking at the distant display. We present HaptiCase, an interaction technique that provides back-of-device tactile landmarks that the user senses with her ...

Understanding source code is crucial for successful software maintenance, and navigating the call graph is especially helpful to understand source code [12]. We compared maintenance performance across four different development environments: an IDE without any call graph exploration tool, a Call Hierarchy tool as found in Eclipse, and the tools ...

Understanding source code is crucial for successful software maintenance. To understand source code, navigation in the call graph has been shown to be particularly important. Programmers often employ a two-phased strategy for effective call graph exploration. We present Blaze, a source code exploration tool designed to explicitly support this strategy. ...

Getting the timing and dynamics right is key to creating believable and interesting animations. However, using traditional keyframe animation techniques, timing is a tedious and abstract process. In this paper we present Dragimation , a novel technique for interactive performative timing of keyframe animations. It is inspired by direct manipulation ...

Direct manipulation video navigation (DMVN) systems allow to navigate inside video scenes by spatially manipulating objects in the video. Problems arise when dealing with temporal ambiguities where a time span is projected onto a single point in image space, e.g., when objects stop moving. Existing DMVN systems deal with these ...

Most presentation software uses the slide deck metaphor to create visual presentation support. Recently, canvas presentation tools such as Fly or Prezi have instead begun to use a zoomable free-form canvas to arrange information. The effect of this change in format on the authoring process of presentations has been investigated ...

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 ...

User feedback for deployed software systems ranges from simple one-bit-feedback to full-blown bug reports. While detailed bug reports are very helpful for the developers to track down problems, the expertise and commitment required from the user is high. We analyzed existing user report systems and propose a flexible and independent ...

MudPad is a system enriching touch surfaces with localized active haptic feedback. A soft and flexible overlay containing magnetorheological fluid is actuated by an array of electromagnets to create a variety of tactile sensations. As each magnet can be controlled individually, we are able to produce feedback in realtime locally ...

MudPad is a system capable of localized active haptic feedback on a touch screen. We use an array of electromagnets combined with an overlay containing magnetorheological (MR) fluid to actuate a tablet-sized area. As MudPad has a very low reaction time, it is able to produce instant multi-point feedback for ...

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.

Hobby chefs have various ways to learn cooking-paper recipes or cooking shows, for example. However, information in paper recipes may require prior experience to be understood and a television show cannot adapt to a viewer's individual speed. Based on our findings on cooking habits, we are developing PersonalChef to unravel ...
