提出了一种基于力反馈和物体变形的虚拟筷子系统。根据筷子正确的握筷方式,利用杠杆建立力反馈模型,将力施加到食指和中指上。通过预先求取刚度矩阵的逆,实时获得物体的变形。我们进行了实验来比较虚拟物体的硬度。结果发现,硬度的对数差为0.4或更大的虚拟对象之间可以实现几乎100%的识别率,而当硬度的差小于此时,获得较低的识别率。
This paper proposes a virtual chopsticks system using force feedback and object deformation with FEM (finite element model). The force feedback model is established by using a leverage based on the correct chopsticks handling manner, and the force is applied to the index and middle finger. The object deformation is obtained in real-time by calculating inverse stiffness matrix beforehand. We performed experiments to compare the hardness of virtual objects. As a result, we found that a recognition rate of almost 100% can be achieved between virtual objects where the logarithmic difference in hardness is 0.4 or more, while lower recognition rates are obtained when the difference in hardness is smaller than this.
