Description

This paper presents a work carried out for a project to develop a new interactive technique that combines haptic sensation with computer graphics. The project has two goals. The first one is to provide users with a spatially continuous surface on which they can effectively touch an image using any part of their bare hand, including the palm. The second is to present visual and haptic sensation simultaneously by using a single device that doesn't oblige the users to wear any equipment. In order to achieve these goals, we have developed balloon array volumetric haptic display named Volflex. The Volflex, however, has small range of displayed volume. In this paper, we focus on expanding the ability to present varied shape of virtual object from flat surface to volumetric surface. We designed a new volumetric haptic display named Volflex+. It is composed of a group of air balloons controlled by air cylinders. Each air cylinder is attached to a linear actuator so that each balloon is able to move up/down. This configuration drastically expands presented volume..
