For cyclists, well-fitting clothing is essential for comfort and performance during cycling. Preference towards a clothing size is mostly based on comfort perception in a standing position, although the shape of the upper body obviously changes in cycling position. This study gives an indication of the conversion factors from a standing position to...
Chapter
In times of online shopping, it is a challenge to select the right size of the desired clothing without fitting it before ordering. Therefore, this study describes three techniques to predict 3D upper body dimensions. The first method used basic personal parameters (gender, age, weight and length), the second technique used also the shoulder width...
