Ambulatory measurement of human activity 
“Measure what can be measured, and make measurable what cannot be measured.”—Galileo

Our goal is to automatically recognize human behaviour in real-time. That requieres sometimes to deal with unmeasurable variables. We make them measurable by integrating information gathered from multiple simple sensors attached to the body.

Some unmeasurables we make measurable in real-time (a.k.a. research topics):
  • walking step length
  • arms and legs articular angles
  • spine angle
  • intention to change walking direction
  • traveling distance and direction (in GPS denied environments)
This research turns out to be a potentially useful tool for our clients

We address the design, implementation and applications of wearable measuring systems where body worn sensors, such as inertial sensors, electromyography and galvanic skin response sensors, BCI and ECG devices, gaze trackers, thermal sensing, microphone, camera, electrodes, among others, are used for behavior sensing.

Our work should lead to the development of novel devices, based on simple sensors attached to the body, able to provide real-time information about the user behavior while satisfying easiness, privacy, reliability and cost requirements.

Our research has applications in several application domains: gait analysis, pedestrian navigations systems, health hazard monitoring, eldercare, rehabilitation devices and assessment, prosthesis/orthosis, exoskeletonshuman-robot interaction or affective computing.
