Tangible interaction with the WILD platform combining 32 high-resolution screens, a motion capture system and a multi-touch table. Here, a brain model is used to control the “Gray Substance” application. By pointing a groove of the cortex with a rod, the user can select the corresponding groove on the 64 3D reconstructions of patient brains, but also synchronize the displays so that all are viewed from the same angle. This operation is frequently performed as part of the verification of 3D reconstruction algorithms from MRI data, but also in order to detect in the morphological variations of the cortex, the signature of certain pathologies of development.
