“…A. Darvishi confirms that an information technology environment using various sonorities provides support for the understanding of the interactive process [9]. But this study doesn't say if sounds alone could be sufficient for correct interaction.…”

“…Alty points out that music is usable as the main means of communication, with three centres of interest: the communication of musical algorithms, debugging, and communication for blind people [10]. Regarding this third area, A. Darvishi uses sound synthesis in a virtual environment accessible to the blind, each sound being the result of a particular configuration of the environment [9]. One of the problems of this approach could be the difficulty to convey precise information with sound synthesis, because of its very abstract nature, not really suitable for communication.…”

Abstract. In games, we can discern two approaches to learn how interactivity works: the instructions for use and the interactivity itself. The number of spoken languages is evaluated at more than six thousand eight hundred: for this reason, instructions for use can't make games understandable for all potential users, which is especially true for audio games accessible to visually impaired players, since those games can not count on visual support and have small budgets. Such games don't provide translation, perhaps because of a lack of cost effectiveness. So, if the purpose of a game is to learn in a friendly but challenging way how interactivity can become complex, why not start this process from the very beginning, without the need of textual instructions? Some musical toys have their sighted users accomplish very simple actions in a funny way, without the need of instructions for use. Moreover, video games show us that it is possible to separate the learning process of a complex task in small steps easy to master. We have made a game according to those principles and realized an experiment to test it. All the players managed to progress in the game but not all understood all the principles of the game. For this kind of game, we assume that players do not have to understand the game during the first contact but they have to be encouraged to continue interaction. At last, the increase of the difficulty level has to be very progressive.

Nonverbal communication helps to compensate many hidden meanings omitted from spoken language. In some situations, nonverbal communication may even take the place of verbal communication. In this paper, we introduce how nonverbal acoustic communication can be utilized in human-computer interaction. We first overview acoustic techniques for nonverbal communication. Then we provide a design framework of nonverbal communication based intelligent agents. We demonstrate an example of the design using an experimental iPad game.

“…For instance, research conducted by Darvishi et al [17,18] looked at mapping GUIs into auditory domains through "impact sounds" based on physical modeling. Ultimately, these sounds are used to convey information to the user regarding the objects in a GUI environment.…”

With over thirty million individuals with disabilities being reported in the United States, and with information systems permeating nearly every aspect of society, there is a growing urgency to ensure that everyone has equal access to technology. To render information technologies universally accessible, researchers must have at their disposal an accurate and reliable user model. Through the use of the conceptual framework presented here, accurate assumptions can be generated from knowledge of an individual's impairments, and functional abilities to influence the creation of a user profile. Ultimately, user profiles serve as a vital attribute of user models applied to the design of technology in an effort to achieve universal access.
