The sys­tem is ready and works now toge­ther with the Loko­mat. As a first sce­na­rio we imple­men­ted obst­a­cle wal­king. You see on our huge screen a tiny figure, wal­king along a path in an ani­ma­ted land­scape. Obst­a­cles are on the path and as soon as they approach the figu­rine, a dif­fe­rent gait tra­jec­tory is swit­ched to. We got these tra­jec­to­ries by recor­ding obst­a­cle cros­sings of six per­sons. An addi­tio­nal fea­ture is sound, also being activa­ted when the obst­a­cle is cros­sed. We showed all this at a demons­tra­tion for guests on Wednesday.

Now with the setup ready sci­ence can start. But now a huge amount of pos­si­bi­li­ties emerge. One could inves­ti­gate the influ­ence of very many para­me­ters on gait per­for­mance or pati­ent moti­va­tion. Feed­back stra­te­gies can also be tar­ge­ted. I have some ideas for sound feed­back. Using MIDI almost all musi­cal pat­terns could be crea­ted, piano sound being the most pro­mi­nent one. I thought about imple­men­ting a bass line (wal­king bass) and chords only being played when spe­cial events (e.g. obst­a­cle approa­ching) occur.

For the demo on Wed­nes­day I used a sim­ple II-​​V-​​I sequence: Dmin7, G7, C7. But this is just the beginning.
