Robert Walter

PhD Student

I am an HCI researcher. My interests are focused on full-body interaction with large interactive public displays, concentrating on immediate comprehension and usability. I am PhD student at the Quality and Usability Lab of Telekom Innovation Laboratories and Technical University of Berlin.


  • Glimpse


    In this work we use a head-mounted eye tracker to record visual behavior of 25 users interacting with a public display game that uses a silhouette user representation, mirroring the users' movements.

  • Squint


    Together with Viktor Miruchna, I built a head-mounted display (HMD), similar to the Oculus Rift. As an additional feature, our HMD allows for binocular eyetracking. The can estimate in what direction, and at what depth the user is looking.

  • Cuenesics


    We propose a design space for hand-gesture-based mid-air selection techniques on interactive public displays, along with four specific techniques that we evaluated.

  • MyPosition


    The project with Nina Valkanova allows for a great and novel way of urban participation: passers-by get the opportunity to place a vote on local topics by performing body gestures in front of a large public display installation.

  • StrikeAPose


    We investigate how to reveal an initial mid-air gesture on interactive public displays. This initial gesture can serve as gesture registration for advanced operations.

  • LookingGlass


    In this project with Jörg Müller we investigated how passers-by notice the interactivity of public displays. We designed an interactive installation that uses visual feedback to the incidental movements of passers-by to communicate its interactivity.

  • Kinect Finger Counting


    In this project with Gilles Bailly we present the adaptation of three menu techniques for free hand interaction: Linear menu, Marking menu and FingerCount menu.

Since 2011, I supervise the exercises and the projects of the Mobile Interaction module of Quality and Usability Lab of TU Berlin. In the exercise, students learn the basics of the famous creative coding environment Processing and get introduced to the Kinect Camera and the OpenNI framework.

Using these tools, students practically apply the interaction design process taught in the lecture and create small projects in groups. The task is to create an intuitive yet engaging interactive public display application.

Within 7 weeks, students go from brainstorming ideas and defining personas of the target audience, over storyboard, conducting interviews with potential users, paper prototyping, to the first iteration of a software prototype. The prototype is then redefined using methods of heuristic evaluation and a think-aloud user study. Students document the progress of their work in a project blog (check the links below).

Mobile Interaction Winter Semester 2012/2013

In that semester we had 15 great projects (70 students) working on the topic of Interactive Waiting Area Experience. Note that the projects displayed here is not my work but the result of student projects of our HCI course! Visit the corresponding blogs to get more information.

Mobile Interaction Winter Semester 2011/2012

In that semester we had 12 projects (57 students). Note that the projects presented here is not my work, but results of our student projects. Check out a list of noticeable projects below!


Players have to place specific body parts on predefined, moving targets on a circle around their body.

While it’s already quite easy to create videos from processing sketches using the saveFrame() function and a video converting tool like the FFmpeg command line tool, this approach comes with some drawbacks. You need relatively large amounts of hard disk[…]
