Talk of Prof. Michael Haller: "NiCE: designing Natural Interfaces for Collaborative Environments"


Prof. Michael Haller





16:00 - 17:00




The research goal of NiCE is to design, develop, and evaluate natural user interfaces. We mainly focus on novel large surfaces and new interaction techniques, which are embedded in our daily-life environment (e.g. living room, conference room, office environment etc.). In this presentation, we will present two projects, the NiCE Formula Editor and Sitz g’scheit.
In the NiCE Formula Editor, we can recognize handwritten formulas to provide in situ computation and visualization. Our editor uses a novel hardware setup, suitable for use as a desktop or whiteboard that disambiguates pen and multi-touch input. In our interface, the pen writes and performs gestures, while touch manipulates. Multiple users can sketch mathematical expressions (e.g. formulas, vectors, matrices, etc.) with digital pens on the interactive surface. These expressions are analyzed and interpreted using the StarPad SDK’s support for mathematics recognition.
In the project Sitz g’scheit, we present three different ways of interrupting people to posture guidance. We developed an ergonomically adjustable office chair equipped with four sensors measuring the office worker’s posture. It is important that users do some training after bad posture and be alerted of this; therefore, we implemented three different alert modalities (Digital Feedback, Physical Feedback, and Vibrotactile Feedback), with the goal to find out which of the techniques is the most effective interruption modality without causing a huge disruption effect. To measure the task-performance, we conducted a formal user study.


Michael Haller is a professor at the department of Interactive Media of the Upper Austria University of Applied Sciences (Hagenberg, Austria), head of the Media Interaction Lab (, head of the Austrian Research Center NiCE, and responsible for computer graphics, human-computer interaction, and augmented reality. His core areas of expertise are visualization and interaction. He received Dipl.-Ing. (1997), Dr. techn. (2001), and Habilitation (2007) degrees from Johannes Kepler University of Linz, Austria. He is active in several research areas, including interactive computer graphics, augmented and virtual reality, and human computer interfaces. His current focus is on innovative interaction techniques and interfaces for next generation working environments. Currently, he leads a team of over 10 researchers and students. In 2004, he received the Erwin Schrödinger fellowship award presented by the Austrian Science Fund for his visit at the Human Interaction Technology Laboratory (HITLabNZ), University of Canterbury (New Zealand), and the Integrated Media Systems Center (IMSC), University of Southern California (USA). The research output includes 13 journal papers and book chapters, and has been presented already in high quality academic conferences and several demonstrations including ACM SIGGRAPH, Eurographics, Disney’s New Technology Forum, and Ars Electronica Festival. In 2006, he was also invited to exhibit his work for five years at the Singapore Science Center. Since 2008, Haller is head of the Austrian Research Studio NiCE, designing natural user interfaces for collaborative environments.
