Manual human-computer interfaces for virtual reality are designed to allow an operator interacting with a computer simulation as naturally as possible. Dexterous haptic interfaces are the best suited for this goal. They give intuitive and efficient control on the environment with haptic and tactile feedback. This paper is aimed at helping in the choice of the interaction areas to be taken into account in the design of such interfaces. The literature dealing with hand interactions is first reviewed in order to point out the contact areas involved in exploration and manipulation tasks. Their frequencies of use are then extracted from existing recordings. The results are gathered in an original graphical interaction map allowing for a simple visualization of the way the hand is used, and compared with a map of mechanoreceptors densities. Then an interaction tree, mapping the relative amount of actions made available through the use of a given contact area, is built and correlated with the losses of hand function induced by amputations. A rating of some existing haptic interfaces and guidelines for their design are finally achieved to illustrate a possible use of the developed graphical tools.
虚拟现实的手动人机界面旨在让操作员尽可能自然地与计算机模拟进行交互。灵巧的触觉界面最适合这一目标。它们通过触觉和触感反馈，对环境提供直观且高效的控制。本文旨在帮助选择在设计此类界面时需要考虑的交互区域。首先回顾了有关手部交互的文献，以指出探索和操作任务中涉及的接触区域。然后从现有记录中提取它们的使用频率。结果汇总在一个原始的图形交互图中，该图可以简单直观地展示手部的使用方式，并与机械感受器密度图进行比较。接着构建一个交互树，该树描绘通过使用给定接触区域可实现的相对动作量，并将其与截肢引起的手部功能丧失相关联。最后，对一些现有的触觉界面进行评级并给出其设计指南，以说明所开发图形工具的可能用途。
