Presentation
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)

Rcent projects
Modelling of gestuality during speech production and reception in semi-guided conversations between two speakers.
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).
Highlighting "disruptive" gestures and movements in Industry 4.0: detection and optimisation of the working environment.
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.
