The invention regards a method and a feedback system for the assessment of motions of a versatile system that use a wireless sensor network attached to the versatile system. The method comprises a training phase and a feedback phase. In the training phase, a defined motion is conducted by the versatile system, whereby sensor data are gathered by the sensor nodes (31, 32, 33). After segmentation (202) of the sensor data into separate segments and the extracting (203) of features, a symbol is assigned to each of the motion fragments. A symbol sequence is formed which represents the complete motion conducted by the versatile system at a sensor node. After repeating at least once the conducting step and/or the analysing step, a reference symbol sequence (207) is formed at each sensor node (31, 32, 33). In the feedback phase, the defined motion is conducted again, and the collected sensor data are analyzed in a similar manner as in the training phase, wherein at each sensor node at least one motion fragment of the present motion is assessed (404) at least by comparing the symbol assigned to the motion fragment with a to be expected symbol of the reference symbol sequence. A feedback (405, 409, 410) is provided to the versatile system depending on the result of the assessment. The feedback refers to a motion fragment and may be provided while the motion is still carried out.

This invention could be used to train surgeons. Although this may be a tiny market, this could have a huge effect. A young surgeon could train the system with an experienced surgeon. In the feedback phase, the young surgeon can recap the correct movement anywhere and anytime.

Potential applications in skills: keyboard typing, handwriting, knitting, tying knots etc. Just imagine how pupils could train the sensors with their teachers and get feedback from the sensors at home while doing their homework!

Potential applications in music (learn, master & apply): playing an instrument, singing, dancing, ballet & choreography.

Perfect for smart toothbrushes: train the sensors together with your dentist and off you go.

Efficiency 2.0 - this invention can be used to train factory workforces. In the training phase, the foreman instructs the workers equipped with the sensors. In the feedback phase, the workers get haptic or kinesthetic responses from the sensor if their movements are outside the best mode of operation.

This invention has real market potential with golf players: a professional golf coach can train the sensor network taking into account the player's physique and movements. The golf player can then use the feedback system at home, in a hotel room or at the driving range to work on his swing.

This invention relates to "a feedback system for the assessment of motions of a versatile system". Such a versatile system could also be a pet (think dog or a cat). Just imagine how you could help your cat or dog to recover from an injury: the sensor would be trained to give the cat or dog haptic responses if the cat or dog moves incorrectly. With LED lighting you could even observe if your pet's movements are correct (green lighting) or incorrect (red lighting).

This invention could be used in shooting ranges of police academies. After a short training phase with a professional instructor, the machine learns the perfect positioning, drills and movements for the cadet. Afterwards, the cadet can rely on the invention's sensor network and feedback system to repeat precise and personally adapted exercises at the shooting range or even use it for dry runs at home.

This patent application could be a stepping stone for a heath insurance provider: either they invest to bring this technology to life or they could profit as soon as this system becomes common-place in a few years down the road.

The new patent claims (November 2017) require that the system provides feedback while the motion of the versatile system (read human) is still ongoing. This makes the invention very interesting: the system is able to warn the user about wrong movements right away.

This patent application has real potential. You can use the sensor network at home when you recover from an injury. More importantly, it is location independent: you can wear it in the gym when you work out, when you run & when you swim. I do hope that I can buy such a product soon!
