日本語まとめ
VR環境で仮想オブジェクトを持って動かすだけで、その動きを再現するシステムを提示。3種類の物理的特性を実験参加者が構築するケーススタディを行なった。VRの経験がない人間でも、短い時間でシステムに慣れることができた。
Abstract
We present Inpher, a virtual reality system for setting physical properties of virtual objects using mid-air interaction. Users simply grasp virtual objects and mimic their desired physical movement. The physical properties required to fulfill that movement will then be inferred directly from that motion. We provide a 3D user interface that does not require users to have an abstract model of physical properties. Our approach leverages users' real world experiences with physics. We conducted a bodystorming to investigate users' mental model of physics. Based on our iterative design process, we implemented techniques for inferring mass, bounciness and friction. We conducted a case study with 15 participants with varying levels of physics education. The results indicate that users are capable of demonstrating the required interactions and achieve satisfying results.
