Haptic technologies have the potential to help the blind community overcome many of the challenges experienced when accessing the Web. With limited design guidance available to web developers, haptic effects could be selected arbitrarily for use on a web page, with minimal consideration given as to how the sense of touch could assist a blind user. Poor interface design is known to reduce the quality of the subjective browsing experience. In this thesis, research has been conducted with the aim of developing effective spatial and navigational cues to address issues of accessibility on a web interface. Using a structured participatory-based design approach, force-feedback cues have been developed to represent objects commonly found on a web page (e.g. images and hyperlinks). The application of a modified version of the approach, has led to the design of tactile pin-based stimuli, which provides similar levels of structural and navigational support to the force-feedback cues. Findings have informed a library of software, with accompanying guidelines for their application on a web page. These are housed within a haptic framework. This tool provides a vital reference for developers, allowing them to replicate effects on their own sites, and offers them support during both the design and evaluation processes. It is left to the discretion of the developer to include the mappings that are most appropriate to the context of the web-based task, and ensure that these cues are targeted to the needs of a broad range of blind individuals when using a tactile or force-feedback device.
