“…The most recent generations of haptic devices transmit feeling through direct contact with the virtual object (e.g., SensAble Phantom Desktop, Immersion Corp.'s CyberForce, Novint Falacon, and Nintendo's Wii). Stemming from the development of these devices, applications have been researched and developed especially for people who are blind, including identification of texture and shape recognition (Semwal and Evans-Kamp, 2000;Sjotrom and Rassmus-Grohn, 1999), mathematical learning environments (Karshmer and Bledsoe, 2002;Van Scoy et al, 2000;Van Scoy et al, 2005;Yu et al, 2001), and acquisition of spatial information (Evett et al, 2009;Lahav and Mioduser, 2004;Sánchez and Sáenz, 2010). Researchers have shown that by exploring VEs that represent RSs, people who are blind can construct a useful cognitive map about previously inexperienced spaces.…”

Structured AbstractPurpose -Virtual environments (VEs) that represent real spaces (RSs) give people who are blind the opportunity to build a cognitive map in advance that they will be able to use when arriving at the RS.Design -In this research study Nintendo Wii based technology was used for exploring VEs via the Wiici application. The Wiimote allows the user to interact with VEs by simulating walking and scanning the space.Finding -By getting haptic and auditory feedback the user learned to explore new spaces.We examined the participants' abilities to explore new simple and complex places, construct a cognitive map, and perform orientation tasks in the RS.Originality -To our knowledge, this finding presents the first virtual environment for people who are blind that allow the participants to scan the environment and by this to construct map model spatial representations.

“…van Scoy and Kawai [15] developed a tool which allowed users to feel the graph produced by a mathematical equation, by "carving out" the function in a virtual haptic surface, which could be felt by the participant using a PHANTOM haptic device (see Figure 2). Unfortunately, they do not report an evaluation of their system.…”

In this paper we discuss why access to mathematical graphs is problematic for visually impaired people. By a review of graph understanding theory and interviews with visually impaired users, we explain why current non-visual representations are unlikely to provide effective access to graphs. We propose the use of multiple views of the graph, each providing quick access to specific information as a way to improve graph usability. We then introduce a specific multiple view system to improve access to bar graphs called SoundBar which provides an additional quick audio overview of the graph. An evaluation of SoundBar revealed that additional views significantly increased accuracy and reduced time taken in a question answering task.

Haptic and Audio Interaction Design

Abstract. Haptic data visualization is a growing research area. It conveys information using the sense of touch which can help visually impaired people or be useful when other modalities are not available. However, as haptic devices and virtual worlds exhibit many challenges, the haptic interactions developed are often simple and limited to navigation tasks, preferring other modalities to relay detailed information. One of the principal challenges of navigation with haptic devices alone, particularly single point-based force-feedback devices, is that users do not know where to explore and thus obtaining an overview is difficult. Thus, this paper presents two types of interaction technique that aim to help the user get an overview of data: 1) a haptic scatter plot, which has not been investigated to any great degree, provided by a force model and 2) a new implementation for a haptic line chart technique provided using a guided tour model.
