The uniqueness of 3D interaction is often used to justify levels of user fatigue that are significantly higher than those of desktop systems. Object manipulation and symbolic manipulation techniques based strictly on first person perspective are also generally less efficient than their desktop counterparts. Instead of considering the two environments as distinct, we have focused on the idea that desktop...
This research investigates how interacting with tangible user interfaces (TUIs) affects spatial cognition. To study the impact of TUIs, a between subjects study was conducted (n=60) in which students learned about the operation of an anesthesia machine. A TUI was compared to two other interfaces commonly used in anesthesia education: (1) a Graphical User Interface (a 2D abstract simulation model of...
A haptic virtual borescope is developed for the purpose of aircraft engine inspection training, similar in spirit to borescope trainers intended for use in gas turbine maintenance training schools. Such devices consist of engine section mockups for use with a real borescope. Our approach instead simulates engine sections in virtual reality, replacing the need for physical mockups. We model the engine...
We present the design and realization of a two-handed input device that is dedicated to the interactive simulation of flexible objects. A set of symmetrical and asymmetrical bimanual interactions techniques has been designed and implemented in a VR simulation system that is used for routing design of cables, hoses and wiring harnesses. A preliminary expert review study showed the benefits of our approach.
This paper presents a new input device called digital foam designed to support natural sculpting operations similar to those used when sculpting clay. We have constructed two prototypes to test the concept of using a conductive foam input device to create 3D geometries and perform sculpting operations. The novel contributions of this paper include the realization that conductive foam sensors are accurate...
This paper proposes a basic technology that utilizes natural objects in the environment and uses them as a simple interface. We focus on an interface that uses a small wooden balance beam. Its input is the movement of the user's center of gravity and the balance on the beam. The user controls the interface by hopping onto it, walking back and forth, jumping on it or leaning his body in a direction...
We present two studies to assess which physical factors influence 3D object movement tasks with various input devices. Since past research has shown that a mouse with suitable mapping techniques can serve as a good input device for some 3D object movement tasks, we also evaluate which characteristics of the mouse sustain its success. Our first study evaluates the effect of a supporting surface across...
We present Dynamic Dragging, a virtual reality (VR) technique for input of smooth 3D trajectories with varying curvature. Users "drag" a virtual pen behind a hand-held tracked stylus to sweep out curving 3D paths in the air. Previous explorations of dragging-style input have established its utility for producing controlled, smooth inputs relative to freehand alternatives. However, a limitation...
Traditional menu designs are not well-suited for command selection on distant displays. We describe a n.ew interaction technique called the "roll-and-pinch menu" (rapMenu), and investigate the design space of remote menu selection using freehand gestural input. The rapMenu maps intuitive hand postures and gestures to a radial menu layout at two levels of granularity: the user rolls her hand...
Abstract This paper introduces a novel pseudo-haptic approach called HEMP - hand-displacement-based pseudo-haptics. The main idea behind HEMP is to provide haptic-like sensations by dynamically displacing the visual representation of the user's hand. This paper studies the possible application of HEMP to the simulation of force fields (FF). The proposed hardware solution for simulating the hand displacement...
Haptic human-machine interfaces and interaction techniques have been shown to offer advantages over conventional approaches. This work introduces the 3D virtual haptic cone with the aim of improving human remote control of a vehicle's motion. The 3D cone introduces a third dimension to the haptic control surface over existing approaches. This approach improves upon existing methods by providing the...
Imagine you are playing a videogame in which you impersonate a wizard who needs to create a potion in order to enchant your enemies. Through a desktop haptic probe, shaped as a baton, you are able to stir and feel the magical fluid inside a bowl. As you follow the potion recipe, you feel how the fluid changes its viscosity, density, velocity and other properties. Various hapto-visual user interfaces...
