I saw the announcement below on another mailing list: Hello, (If you prefer an explanation in French, please scroll down.) As a part of the project NAVIG (http://navig.irit.fr/ <http://navig.irit.fr/> ), we invite you to participate in a brief (20 minute) audio categorization and evaluation test of sounds designed for a navigation aid for the visually impaired. Your participation in this test will be very helpful in our assessment of the sound syntax developed to provide information along a trajectory. The test is not reserved to only those people with visual impairments. The purpose of the NAVIG project is to augment the autonomy of individuals with visual impairments, allowing them to arrive at desired destinations in a more reliable and secure way without interfering with normal travel behavior. Guidance information along the route will be provided with 3D sounds, using acoustically transparent bone conduction headphones. A collection of "sound palettes" have been created to allow users to differentiate between types of information provided by the system (path, point of interest, landmark, …) while giving the possibility of customizing the system to each users aesthetic choices. The results of this test on the sound palettes created will provide us important feedback regarding syntactic and aesthetic choices. Your feedback is very valuable and will enable us to provide the best possible system. The questionnaire has been tested with a variety of screen readers. If you have any questions, if you encounter any accessibility problems to the test, or if you have any comments, feel free to contact us. All answers to this questionnaire will be treated anonymously and confidentially. The results will be used exclusively for the NAVIG project. To avoid any disturbances from ambient noise or interruptions, it is recommended that you situate yourself in a quiet room. The test will be available until the end of October. Please feel free to transmit this questionnaire to any lists or people that you think might be interested. The test is available in both French and English.
