This study focuses on a pressure sensitive spherical screen that aims to promote upper limb exercise. We utilized the characteristic of a photoelastic resin that changes polarization during the deformation in order to detect the pressing force on the screen. We developed a prototype dome screen that is crimping transparent polyurethane elastomer on the silver painted surface. Then we confirmed the change of polarization by capturing the surface with polarized camera when the polarized light was projected on the screen.

本研究的重点是一种旨在促进上肢运动的压力敏感球形屏幕。我们利用光弹性树脂在变形过程中改变极化的特性来检测屏幕上的压紧力。我们开发了一种圆顶屏幕的原型，它是在涂银的表面卷曲透明聚氨酯弹性体。然后利用偏振光在屏幕上投射时，用偏振光相机捕捉表面来确定偏振的变化。
