Spatial sound information/cues may enhance the sense of immersiveness in virtual story telling. However, their role within complex, loosely-structured narratives is little understood. This paper describes a virtual heritage project that aims to convey a factual story using interactive virtual environments. Sound was added to the existing project in an(More)
Speech technology can be used to provide online help to users in situations where visual display of online help is not possible, or has some display-related limitations. Presenting help material in this manner can also complement traditional online help systems. To date, most online help material has been developed with the assumption that the material will(More)
A game controller, and how that controller is supported in a game, can have a significant impact on a player's gaming experience. In recent years there has been an increasing amount of computer game focused HCI research, but the impact of controller-related issues on user experience remains relatively unexplored. In this chapter we highlight the limitations(More)
Adaptations using speech synthesis provide a basic level of access to computer systems for blind users, but current systems pose a number of usability problems. A study was carried out in order to assess the impact of certain issues on the usability of a typical speech adaptation. The results suggest that much work needs to be done on the design of speech(More)
Synthetic speech is widely used to enable blind people to receive output from computer systems. However, speech is slow to use compared with vision and places far higher demands on shortterm memow. These problems are particularly apparent when exploring farge data structures such as lists and tables. An experiment was conducted in which subjects were asked(More)
