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.

Projects

  • Squint

    2014

    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

    2013

    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

    2013

    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

    2012

    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

    2011

    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

    2011

    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.

Teaching

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).
