Research

Stress Detection through Smartphones' data. With the new advent of wearable devices and their associated embedded sensors, it has become possible to collect data from which contextual and behavioral information can be extracted. This work focuses on detecting different stress levels in working environments by analyzing sensor data from smartphones.

Long-term activities segmentation. Activity recognition has become a very active research topic. High accuracy for recognizing simple activities has been achieved, however complex activities are still challenging. Several works have used a rich collection of sensors to detect complex activities. In this work we aim to segment (infer start and end time) complex activities with a single accelerometer.

Contextualized hand gesture recognition. Most of the previous works in hand gesture recognition focus in increasing the accuracy and robustness of the systems, however little has been done to understand the context in which the gestures are performed, i.e, the same gesture could mean different things depending on the context and situation. In this work, we used location information in order to contextualize the gestures. The system constantly identifies the location of the user so when he/she performs a gesture the system can perform an action based on this information.
