AIHM : Alès Imaging and Human Metrology


The Ales Imaging and Human Metrology (AIHM) platform offers mobile solutions and a wide range of services in the following areas:

  • motion, health, human perception,
  • digital imaging and computer vision,
  • acoustics and sonification

Operating on an interdisciplinary basis (from physics to data processing and perception) with immersive experimental protocols and an agile methodology, this platform offers mobile equipment that can be moved entirely. Its main activities are :

  • capture, modelling and optimisation of a moving subject and its environment (visual, sound, spatial), and environmental optimisation
  • automatic data analysis (sound, image, physiological signals, neuroimaging)
  • synthesis, restoration and enhancement (sound, image)


Main equipments


  • Qualisys 11-camera Miqus M3 system
  • QTM software with Eye Tracker module
  • Inertial Motion Units (IMU)

Physiological signals

  • Eye tracking (Tobii pro 2 and Pupil Core)
  • Neuroimaging: electroencephalogram (EEG) and near infrared spectroscopy (NIRS)

Sound and optics

Rcent projects

Modelling of gestuality during speech production and reception in semi-guided conversations between two speakers.

Coverbale interaction (3D rendering, QTM)


Analysis of the optical and visual signature of Palaeolithic works in their current state.
Aim: to provide food for thought about contextualisation (the physical world and the mental universe in the Palaeolithic period).

As part of shoulder movement rehabilitation, creation of a sonification system (sound feedback) to perceive the amplitude of arm joint rotations.


Semaxone, a company spun out of the IMT Mines Alès incubator and supported by the EuroMov DHM research unit, is developing innovative software tools combining the analysis of physiological signals and voice to detect changes in the psychological and cognitive state of individuals operating in difficult environments (e.g. aircraft pilots).
Semaxone responds to safety issues and training objectives by analysing this multimodal data to monitor changes in the operational state (stress, fatigue, etc.) of individuals.
