Abstract

Currently, various force display device are under development. There are two types of devices in terms of mounting method: grounded and ungrounded. The conventional grounded type force display device can accurately present the force by mounting on the desk or floor, but the movable range is limited. The ungrounded type device is wearable type, the user is burdened to some extent and there is a great restriction on force display. In order to solve this problem, the force display device that can be handled in the hand using a slider crank mechanism has been proposed. This device uses human sensory characteristics, and force can be presented by asymmetric acceleration motion. Since this device uses rotating bodies and crank mechanisms, there is room for improvement in terms of size and weight. Therefore, we adopted a cam to generate asymmetric acceleration motion for the improvement. By using cams, it is possible to reduce the number of devices and downsize them. In this paper, we propose the mechanism using cam and confirm the realization of left-right asymmetric acceleration motion for force display. In addition the performance of the force display was confirmed through both experiments: quantitative and subjective.
基于凸轮的非接地力显示概念验证
目前,各种力显示装置正在研制中。从安装方式上看,设备分为接地和不接地两种。传统接地式力显示装置安装在桌面或地板上即可准确显示力,但活动范围有限。不接地式设备为可穿戴式,对用户有一定的负担,对力的显示有很大的限制。为了解决这一问题,提出了一种采用滑块曲柄机构可在手机上操控的力显示装置。该装置利用了人类的感官特征,力可以通过不对称的加速运动来呈现。由于该装置使用旋转体和曲柄机构,因此在尺寸和重量方面还有改进的余地。因此,我们采用凸轮产生非对称加速度运动进行改进。通过使用摄像头,可以减少设备的数量并缩小它们的尺寸。本文提出了一种采用凸轮的机构,并确定了左右非对称加速度运动用于力显示的实现。并通过定量实验和主观实验对力显示的性能进行了验证。
