Mimic is a sport suit with embedded sensors which can turn user's motion into 3D directly without any help from cameras or any other additional devices. Through research, to learn sports effectively, people need the ability named proprioception which is the power sense the relative position of neighbouring parts of the body and strength of effort being employed in movement. It's very important for sports learning. Actually, all the great sport players have this ability. On the other hand for people who don't have it, they need additional help to assist them to compare how their bodies move and adjust it, which means they need a coach or a camera to film themselves. However, in a survey of this project, only few people, less than 20%, would like to have a coach more than 5 hours to learn a sport, and filming ourselves is also always tricky, for example to keep in the center of the screen or to catch a good angle of view. Hence, Mimic is created to adjust this main issue of sport learning and it also provides some very convenient features such as image mapping/comparing or giving feedback via vibration or sounds.
INTERVIEW WITH PEOPLE
To actually try out some Moving sports or exercises and try to feel/observe it very carefully base one the insight of skills transferring/learning gained from previous interview and research.
INTERVIEW WITH SPORTS TRAINER
EXPERIMENTS ABOUT PROPRIOCEPTION
This experiment is designed to see how proprioception affects how we sense and control our arm in the space, and to see could we improve sensing/controlling by comparing the results of our arm projecting coordinates.
In experiment 1, testees have to try to move the projection of their arms onto the target square area continuously for five times without see the result of each time they made attempt. At the end, only 2 out of 9 could move the projection onto the square at least more than once by sense their arms only.
In experiment 2, testees again have to try to move the projection of their arms onto the target square area but this time they could see the result immediately of their attempts each time they tried. In this experiment, 5 out of 9 could successfully move the light onto target and even for those who failed, we could still very clearly see testees are correcting their arm each time by comparing the previous feeling of their arms and the results on the paper.
DESIGN THROUGH MAKING
While doing the research, interview, trails and experiments, at the same time I was also making things quite causally according to the very preliminary and immature ideas, because making is one of the best resources of finding a refined idea. Below is a quite simple idea that I want to read the information from our body due to the insight of one of the interviewees' experience of running skills learning/transferring through internet.
Successfully fetch the data from our moving boday, but then what? It seems quite hard to see any manifest enlightenment from it. Then visualize the data should of course be a good idea to do next.
FINAL CONCEPTS DEVELOPMENT
Through all of above, the concept of creating a device which could easily record our body motion seems logical, practical and feasible. The only problem is that mechanical reading device is too bulky for the product we have to put it on for sport. According the experience of visualizing the data, we learnt the angles to XYZ coordinate of the specific end of arm sections are all what we need for the goal we want to achieve. Therefore, 9 degrees of freedom sensor would do the job the best.
