About us

The Human-Computer Interaction group of the Leibniz Universität Hannover was founded in July 2012. We are working on new interaction techniques for mobile, embedded, and ubiquitous systems.

What's up

Aug 01, 2016 Winter Semester 2016/17

The times and locations for the classes of winter semester 2016/17 have been updated.

Jul 23, 2016 Niedersächsische Talente-Akademie

At the Niedersächsische Talente-Akademie we give a one-week course on Android Game Programming. Students of schools from all over Lower Saxony develop 2D games with touch screen and accelerometer control using the libGDX framework. The results will be presented and demonstrated to other students, parents, and faculty.

Jun 09, 2016 Novel emoji keyboard at MobileHCI 2016

We will also present a paper on a novel entry method for emoji at this year's MobileHCI conference. Instead of having to select emoji from long lists with many pages, here all emoji are shown at once. Users zoom in to pick the emoji they want. This kind of interface supports building spatial memory and aids in exploration of available emoji. This paper is based on work Dennis Stanke did for his bachelor thesis. Check out the video below and be sure to grab the preprint of the paper. We are planning to release a public version of the keyboard later this year. Stay tuned!

Jun 06, 2016 Indirect Light Feedback at MobileHCI 2016

At this year's MobileHCI conference we will present our work on indirect light feedback, a novel notification channel for smartwatches. This paper is based on work Justyna Medrek did for her bachelor thesis. Check out the video below and be sure to grab the preprint of the paper.

Apr 13, 2016 Peripheral Interaction Book

In their Human-Computer Interaction Series, Springer has just released a great new book on Peripheral Interaction: Challenges and Opportunities for HCI in the Periphery of Attention. If you are at CHI this year, be sure to drop by the Springer booth to have a look at the book. As part of a wide selection of chapters detailing specific aspects of peripheral interaction, Henning Pohl has contributed a chapter on Casual Interaction: Moving Between Peripheral and High Engagement Interactions.
