At first glance, multi-element forearm mounted vibrotactile displays would appear to have considerable potential as an output device for mobile computing. The devices are small, robust and discrete, and the body site both easily accessible and socially acceptable for such a purpose. However, due to the absence of a thorough account of vibrotactile(More)
This article presents a comprehensive exploration of the issues underlying haptic multimedia broadcasting from the processes of contents creation through transmission and finally to viewing and interaction. It also describes the implementation of a prototype system as a proof of concept and demonstrates two possible content scenarios using this system. To(More)
V iewer expectations for rich, immer-sive interaction with multimedia are driving new technologies— such as high-definition 3D displays and multichannel audio systems—to greater levels of sophistication. While researchers continue to study ways to develop new capabilities for visual and audio sensory channels , improvements in haptic channels could lead to(More)
Sensory function is essential for functional post-stroke recovery and control of basic hand movements like grasping. Despite this fact, therapy focuses strongly on motor aspects of rehabilitation, requiring active participation and thus excluding stroke patients with severe paresis. The aim of our novel therapeutic approach combining virtual reality, based(More)
This paper proposes an instrumented handle with multimodal augmented haptic feedback, which can be integrated into a conventional white cane to extend the haptic exploration range of visually impaired users. The information extracted from the environment through a hybrid range sensor is conveyed to the user in an intuitive manner over two haptic feedback(More)
Providing haptic cues can generate increased levels of presence in users as they interact with tangible objects. In this paper, we present button effects delivered by air-jet displays with the aim of providing click-like sensations when virtual buttons in an AR environment are pressed. We derive the profile of the haptic output by measuring the force(More)
