Questions regarding his presentation on his original research "Cell Phone Accessibility Evaluation Study for Persons with Visual Impairments" presented on the panel "Human Factors: the end-user experience" Q:“Have you considered that your proposed prototype should be track-able and locate-able in case of emergency and that there should be a national monitoring and response center?" A: "Yes, for multiple reasons we desire our prototype to be track-able and locate-able. We are currently disappointed with the ability of GPS to provide reliable and accurate "track-ability" in the Atlanta Area, especially in the summer when the air is laden with humidity and/or heavily laden clouds are overhead, not to mention thunderstorm and conditions of heavy rainfall that are tantamount to an emergency for persons who are blind. In fact, I would like to ask anyone who has been testing tracking systems under such conditions to please let me know your results. I can be reached via email at ross0128@bellsouth.net" Q: “How can we get a list of all the phones tested by the VA?” A: "Please email me at: ross0128@bellsouth.net. I will gladly send you our current list of phones that have been/are being evaluated."
