The BMS lab continously looks for new instruments, devices and facilities to better aid students and researchers. This means that we have a growing and changing catalogue with a wide variety of equipment. This month we acquired one major new capability as a result of our search for new and useful equipment and we provide some updates on existing equipment.
Facial Expression Analysis (FEA)
Next to studying human behaviour and responses to stimuli using physiological sensors and eye tracking, it is now possible to research facial expressions, responses and micro-expressions using the AFFDEX and FACET algorithms. They can be studied invidually or they can be combined, also with subjective survey responses.
The FEA module provides 20 facial expression measures (action units), 7 core emotions (joy, anger, fear, disgust, contempt, sadness, and surprise), facial landmarks, and behavioral indices such as head orientation and attention. These output measures provide probability values to represent the likelihood that the expected emotion is being expressed. Summary scores of engagement and valence are also provided, giving you an overview of the overall expressed response. Analysis can be done on-line and posthoc.

Noldus Observer XT: As one result of our EFRO BCI Testbed project, we now have an Observer XT 14.0 licence available for usage in BMS Lab. Lending time limits apply. Support from vendor is available.
Eyetracking in VR: Starting December, we have available a Varjo eyetracking-capable VR headset (https://varjo.com/products/vr-2-pro/) and some Rift S sets.
AR: From December onwards, a Hololens 2 Augmented Reality kit is available for projects.
Embr Wave Bracelet: Using this bracelet, subjects can be heated up and cooled down. Also available from December onwards. https://embrlabs.com/products/embr-wave
ExperiVan: From November, the ExperiVan mobile research lab is available again for field research. It has heating. Contact me for more information.
Lab rooms, Experivan, iMotions and Observer are available for both students and staff through our reservation system (https://bmslab.utwente.nl/sign-up-your-project/).
Varjo headset, AR and Embr are available for usage in the BMS Lab labs. Sign up through our reservation system (https://bmslab.utwente.nl/sign-up-your-project/). Development and support from our engineers is available (80 hours limit) for BMS clients, or need be funded elsewhise. Other VR sets available include mobile and fixed sets (Oculus Rift S/Quest/Go, HTC Vive). They are available for lending, usage in ManouVR, and the mobile lab ExperiVan. Be sure that ethical approval is arranged.
