Usability Lab (ULab)
The ULab is located in Nobelstr. 5, and is available for research studies and student projects. It has the following equipment:
- Eye-Tracker to automatically record the gaze patterns of a user. This allows for example to find out which screen element the user focuses first, or if a user takes notice of the help button at all.
- HD Cameras to record user studies in high resolution. This camera is mounted at the ceiling of the ULab. It is well suited to record user interactions with mobile devices such as smartphones and tablets. Additional HD cameras are available which can be mounted on top of screens or on tri-pods. With them, we can record a user's facial expressions, or their input via keyboard and mouse. Also, we can stream the video of any camera live to remote observers.
- Video Editing and Annotation Software. We can comment and annotate videos of user studies afterwards for analysis, for example to mark a repeated user error, or to measure task times.
- Spotlights on Tri-Pods. We have multiple 500W spotlights on tri-pods. With them, we can simulate diverse illumination conditions, from very dark to sunlight. For example, we can investigate the usefulness of color combinations on a outdoor ticket machine in the open sunlight.
- Sensors for Gesture Recognition. With them, we can conduct user tests with various hand and body gestures, for example in the context of smart home control.
- Microsoft Surface 2.0 Touchtable to use interactive applications.
Mobile Learning and game development for mobile devices: Our Mobile Lab is well suited to conduct research studies and student projects in mobile media, smart home and embedded systems.It has the following equipment.
- We offer up-to-date mobile devices such as smartphones and tablets by various manufacturers and platforms for students' development and validation work. They can create mobile applications (apps) for platforms such as iOS and Android.
- The Mobile Lab has its own mobile network infrastructure for test purposes with GSM and GPRS/EDGE networks, as well as with Bluetooth networks.
- Our smart home area provides a set of home multimedia devices, together with hardware for setting up a wireless home communication system. This is also the basis for validation of technologies for energy efficiency and load balancing in the context of smart metering and a smart grid infrastructure.
- The lab features work places for the development of embedded systems (Arduino, Atmel boards), and a work place for the development of custom electronics hardware.
- For infotainment and automotive we have an infotainment system and a dashboard combi instrument of a Porsche Cayenne Hybrid, as well as LED head lights of a Porsche Panamera. Our lab has most recent hardware and software equipment for connection with CAN bus (also Most, FlexRay), including those by the company Vector Informatik.
- We develop a wide range of applications in collaboration with industry, as a result of student projects and bachelor and master theses. These range from location based services, remote control and diagnosis of devices, mobile information systems, mobile payment systems, to mobile learning and development of games for mobile devices.
