Master Wheel was a professional photography equipment project that Wenbo participated in when he worked in DJI. It was designated for accurately controlling the three-axis stabilization of cameras. In order to increase the user comfort and improve the product appearance, Wenbo proposed to move the rotatable rocker module from the right to the center which greatly distinguished from the other competitive products on the market. The details such as the arrangement of the keys, the height of the knob, the order of operation etc. must be carefully considered for a professional device. The team finally accomplished this product by repeated testings and several version adjustments and tremendously impressed the industry.
