On The Move
To move is a healthy lifestyle. Many government campaigns are trying to convince us over and over again. It is a challenge to stimulate more people to practice sports. Unfortunately, moving is less of a custom for some people than for others. For example, people who cannot move without treatment, due to a serious injury or handicap. Others are so talented at moving that they are practicing top sports and are constantly looking for new ways to improve their performances. The Golden Video On The Move demonstrates how multimedia-technology can support both categories.
On The Move demonstrates two applications of an infrastructure that enables video teleconsulting. The infrastructure was initially developed for physiotherapists (FysioLog), but in the meantime the world of sports is using the platform as well (SportLog).
Sportsmen have added their own Trainer's Cockpit, a tool to be used in training sessions. Athletes and their coaches register relevant data automatically during exercises. On The Move shows how several top class swimmers are video tracked during their trainings. Speed, variations in speed and the frequency of strokes are measured. This data will be analyzed and linked to the matching video fragments in their personal sports diary.
Innovations
The platform for video teleconsulting structures the interaction between several therapists/trainers/specialists during teleconsultations. The platform simplifies the use of (patient) videos, other image material, and sensor data for movement analysis. The use of video analysis - as applied in Trainer’s Cockpit - to enable automatic ánd passive (=no measure instruments on the body) training registration is also new. There is currently no competitor systems with these features.
Technology
FysioLog and SportLog both use sensitive multimedia data, for example patient data, crossing organizational borders. The infrastructure enables several organizations to take a person-oriented look at information. For this, it is necessary that the organizations involved can follow their own work flow parallel and independently and that privacy is guaranteed. The infrastructure is prepared for this. Moreover, users can watch the videos image per image and synchronized with bio signals, during which angles between joints can be measured. Afterwards the therapist or trainer can study the elapse of movement in detail.
Video tracking and behavior analysis by computers is a complex issue that until now has hardly been solved. By testing the latest technology on top class swimmers, many problems associated with video tracking and behavior analysis can be overcome. These solutions enable MultimediaN to develop a system that provides useful (quantitative) information (like speed and frequency of strokes) to elite coaches and athletes to help them win more medals.
Applications
At this moment, ten physiotherapists at the Medical Centre of Twente and the Roessingh Medical Rehabilitation Center are using FysioLog. In Groningen a similar network is active and by now FysioLog has been picked up by the physiotherapist community and is expanded nationwide. The infrastructure, as applied at FysioLog, is built in such a generic way that other fields can use it as well. Within the care industry, examples could be mental health care and intensive youth welfare work.
SportLog was created especially for top class sportsmen and their coaches. It is in use at the swimmer’s union and is in the meantime introduced in other sport's unions as well.
The Trainer’s Cockpit is also especially designed for athletes and their coaches. It is used to measure the stroke frequency of swimmers, but is relatively easy to apply in practising and analyzing other sports. A spin-off is constructed to analyze the start of swimmers. Of this for instance Pieter van den Hoogenband can benefit. If he can improve his start, new world records would come closer within reach for him.
The methods and algorithms developed can also be applied in traffic tracking systems and camera security, as shown in the Golden Demo The Surveillance Dashboard.
