“…Tactile interfaces are becoming a much more viable crossmodal technology and have been gaining popularity in many fields including virtual reality [7] and assistive technologies ( [8]; [9]; [10]). There is, however, limited research focus on using tactile displays as an alternative modality to audio information, even though the skin is an effective organ for receiving audio and visual stimuli translated into the tactile domain [11].…”

The Emoti-Chair is a new universal design for a multimodal entertainment chair to create a tactile entertainment experience for accompanying audio/visual presentations. We presented the Emoti-Chair as part of an exhibit at a public science museum focusing on children's perspectives on global warming and energy use. We asked museum-goers who experienced the chair to answer questions about their experience in the Emoti-Chair. Major findings indicated that the chair was generally found to be comfortable and enjoyable and that young children enjoyed the experience more than adults or youth.

“…Thus, many of the useful navigational options would be lost. In addition, the properties of human short-term memory restricted the amount of information to be hold [1]. Too much information can cause the screen reader users to be overloaded.…”

“…Audio and haptic modalities have been used to improve the traditional practice of using audio as the sole modality to assist the visually impaired. The utilization of multi-sensory modalities allows the visually impaired users to have a "richer and more flexible" way in acquiring information non-visually [1].…”

The limitations of a Website's accessibility in terms of its text attributes representation in web pages hinder the visually impaired users from having a comprehensive understanding of the web content. Current assistive technology such as screen reader and refreshable Braille device are unable to represent this non-textual attributes to the visually impaired. This paper presents a study that examines the significance of text attributes to support Web accessibility and improve understanding of the content. It was hypothesized that the synchronization of audio and haptic feedbacks could improve Web accessibility through text attributes identification; thus, providing comprehensive understanding of the webpage. The study involves development of a prototype system that synchronizes audio and haptic to read webpage and represents text attributes. A mixture of qualitative and quantitative data collection methods was adopted. Interviews with the visually impaired users were conducted to gather their requirements for the prototype. A user testing involving those who suffer from high degree of visual impairment was carried out to evaluate the prototype. B The findings show significant improvement in web browsing performance and text attributes identification using the prototype as compared to the existing screen reader.

“…Research prototypes combine haptic devices with auditory displays (e.g., Omero [6] and Haptic Soundscapes [14]) 2 The design of displays that combine haptic and auditory feedback to present mathematical functions is also present in the literature (e.g., [4]), but this paper focuses on displays of two dimensional map data. or a tablet with stylus (e.g., iSonic [18,19]).…”

“…The mGIS software broadcasts standard system messages that can be used by accessibility tools such as screen readers to convey textbased messages. During evaluation, the mGIS ran on a Windows platform and relied on JAWS (Job Access With Speech) 4 4 JAWS (http://www.freedomscientific.com/ products/fs/jaws-product-page.asp) to render speech feedback. The messages could be used by text-to-speech software on other platforms (e.g., VoiceOver 5 ).…”

Spatial data are increasingly available, but the ubiquitous use of graphical displays to communicate such data renders it inaccessible to people who are blind or low vision. Not only does this affect the level of access to data, it also results in limited educational opportu nities due to a lack of accessible maps and geographic information systems. This lack may be due in part to the challenge of creating a system that provides a usable display without relying on vision. A simple replacement of symbology from a map intended for a two dimensional graphical display with parameters for other modalities such as audio with one primary axis (time) is insufficient.To address the need for an accessible learning materials, we present a minimal geographic information system (mGIS) that uses an au ditory display in combination with a tablet with stylus input device. Non-speech audio communicates attribute data, text-to-speech soft ware renders feedback from the application menus, and kinesthetic feedback from actively controlling the stylus conveys location within the display. This paper presents details of the software imple mentation, discusses the development of an auditory symbology for choropleth maps (maps that display patterns of data over geo graphic space), and describes initial evaluation of usability.
