Comparison of Experts´ between Non-experts´ Apple Peeling Skills and the Designing of Learning Support System

Through experimentation and analyses of apple peeling, we examined the implicit knowledge necessary to perform study support for exercise and performance. A pressure sensor, an eye-mark recorder, a miniature wireless camera, and a surface electromyography were used to assess actions of 10 examinees (6 men, 4 women) during an experiment, which revealed three main differences between experts and non-experts: holding of the kitchen knife using the index finger to the little finger, use of the right thumb, and holding the apple with the left hand. Results show that securely holding the apple and the kitchen knife is important. Finally, we designed the skill learning support system.
