“…Because encounter type interfaces tend to keep the user finger free from mechanical constraints it is possible also to stimulate multiple fingers, in particular using a set of patches one for each finger [9], [8], [7]. The aim of a multiple finger interface is to provide not only the exploration of objects but also the grasping of objects [14].…”

Haptic interaction with virtual objects is typically tool mediated, or in alternative it constraints user's body in someway, like it happens in exoskeletons that cannot be totally transparent. Encounter type haptic interfaces aim at hands free haptic interaction, that is more natural and can be applied in contexts in which the user moves in the space around the interface. This paper presents a system that allows a palm based haptic interaction in a large workspace using the principle of encountered haptics. The system is evaluated in a surface exploration task and compared against the same task performed with a standard haptic interface. In this type of task this type of interface is better suited, providing a smoother feedback to the hand during the movement over the surface.

“…In [3], the authors analyzed interactions within a car cockpit and concluded that a three-finger haptic interface addressing the thumb, the index, and the middle fingertips is necessary to render such interactions in a proper way. Another approach is proposed in [4]. An encountertype device is designed to physically replicate the geometry of some empirically selected objects.…”

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.

“…The hand is theoretically thought to interact with these objects in a realistic way. As an example, the authors in [6] roughly extracted contact profiles from grasps of various daily life empirical objects. They concluded that the contact points are distributed over a sphere which centre is located in the middle of the back of the hand.…”

Haptic interfaces are purposed for the simulation of physical interactions with a virtual environment in a realistic way. Their design is often based on a compromise between the interaction capabilities and mechanical design complexity. This paper is aimed at providing a methodology that helps tuning this trade-off. A survey of both manipulation and exploration taxonomies allows the identification of elementary hand contact areas with their associated frequency of use. The relative importance of these areas is illustrated by the building of an interaction map for the hand. Some combinations of these elementary areas, with their frequency of use, are then organised into a graphical tree as a function of their complexity. This tree allows to review some existing devices and to propose some guidelines for improved designs.
