A latest research by Affiliate Professor Lu Fei’s human-computer interplay analysis staff from Beijing College of Posts and Telecommunications has proposed a three-dimensiona menu that may “bloom within the palm.”

The analysis paper is titled “LotusMenu: A 3D Menu utilizing Wrist and Elbow Rotation Impressed by Chinese language Conventional Image,” revealed in Science China Data Sciences. Based mostly on the metaphor of the normal lotus sample, the researchers proposed a 3D LotusMenu that makes use of the rotational movement of wrist and elbow to regulate the menu choice.

Within the design of this interactive expertise, the researchers corresponded the form of the lotus to the 3D rotation gesture: Mapping the number of round petal teams to the rolling gesture of the elbow (Determine 1(a)), the number of layered petals to the pitching gesture of the wrist (Determine 1(b)), and the number of round lotus seeds to the yawing gesture of the wrist (Determine 1(c)). In the course of the interplay, there may be virtually no shoulder motion, in order that the gesture could be simply carried out inside a small vary of movement. As well as, the rotation of the wrist and arm is merged as a lot as doable, additional decreasing the fatigue attributable to gestures.

Within the experiment, the researchers in contrast the person efficiency of LotusMenu and conventional linear menus. The outcomes present that LotusMenu can considerably scale back the completion time of the choice activity with much less fatigue. This consequence can increase the appliance of 3D rotating gestures in human-computer interactions, and has vital reference worth for the long run software of 3D rotating of interactive elements in large-screen interactive techniques and digital actuality techniques.
