  1. A Limited Communication Domain Mobile Aid for a Deaf patient at the Pharmacy MB Motlhabi and WD Tucker Computer Science Department, University of the Western Cape, Private Bag X17, Bellville 7535, South Africa. INTRODUCTION USER INTERFACE RELATED WORK • This paper discusses a prototype for a health communication aid on a mobile phone to support a Deaf person visiting a public hospital pharmacy to collect medicine. • Deaf with a capital “D” is different from deaf in that Deaf people primarily use sign language to communicate[1]. • The mobile prototype will facilitate communication in a limited domain scenario that helps a Deaf person use South African Sign Language (SASL) and text to communicate with a non-signing pharmacist. • We studied the dialogue and extracted the most relevant content between the a Deaf patient and a pharmacist during medicine dispensing. • We then translate instructions and recommendations from the pharmacist in text to SASL video for a Deaf patient to review later. • Our prototype is not an expect system and does not use Artificial Intelligence techniques. • MobileASL • MobileASL is a video compression project that enables mobile wireless cell phone communication through sign language. • Attention is given to frame-rates, Region of Interest (ROI) and bit-rates so as to not compromise sign language video quality[4]. • TESSA • TESSA is an interactive system that operates in a limited domain to aid transactions between a Deaf person and a clerk in a Post Office by translating the clerks’ speech to sign language. • ViSiCAST • ViSiCAST was designed to improve the quality of Deaf people by widening their access to services and facilities enjoyed by the community at large[3]. • Pharmacist interaction • The pharmacist reads patient information from SignSupport to check for inconsistencies like allergies and environmental conditions. • Should there be any inconsistencies then SignSupport will guide the pharmacist in letting the patient know what has gone wrong and what is being done to fix the problem. • If all went well the pharmacist enters instructions from a paper prescription from the doctor in the phone to be later viewed in SASL by the patient. • Deaf patient interaction • The patient can update their background information and history by answering a guided set of questions in SASL to be later viewed by the pharmacist. • After consultation with the pharmacist, the patient can view medical instructions, warnings and recommendations from the pharmacist in sign language video. • All needed sign language videos are pre-recorded and stored on the phone.

FUTURE WORK RESEARCH PROBLEM • How can we design, develop and evaluate a limited domain exchange mobile tool that will facilitate seamless communication between a Deaf patient and a pharmacist at a public hospital pharmacy during medicine dispensing.
