Fighting Malicious Designs: Towards Visual Countermeasures Against Dark Patterns

Dark patterns are malicious UI design strategies that nudge users towards decisions going against their best interests. To create technical countermeasures against them, dark patterns must be automatically detectable. While researchers have devised algorithms to detect some patterns automatically, there has only been…

User-Aware Rendering: Merging the Strengths of Device- and User-Perspective Rendering in Handheld AR

In handheld AR, users have only a small screen to see the augmented scene, making decisions about scene layout and rendering techniques crucial. Traditional device-perspective rendering (DPR) uses the device camera's full field of view, enabling fast scene exploration, but ignoring what the user sees around the device…

What's That Shape? Investigating Eyes-Free Recognition of Textile Icons

Textile surfaces, such as on sofas, cushions, and clothes, offer promising alternative locations to place controls for digital devices. Textiles are a natural, even abundant part of living spaces, and support unobtrusive input. While there is solid work on technical implementations of textile interfaces, there is litt…

Shaping Textile Sliders: An Evaluation of Form Factors and Tick Marks for Textile Sliders

Textile interfaces enable designers to integrate unobtrusive media and smart home controls into furniture such as sofas. While the technical aspects of such controllers have been the subject of numerous research projects, the physical form factor of these controls has received little attention so far. This work invest…
