Abstract [en]

An increasing number of people in Sweden are having problems with their hearing ability. The three major tools to aid hearing-impaired and deaf individuals are: hearing aids, special telephony, and alerting systems. Both hearing aids and telephony have seen a huge technical development. Hearing aids have gone from huge ponderous devices to small delicate in-ear devices. Simple text telephones have evolved into total conversation telephones with audio, video, and text all operating in real time. Although smart lamps and other alerting services not specifically made for hearing-impaired individuals do exist, the development of alerting system is unsatisfactory. The gap in technology is a huge problem and integration between modern products and alerting systems is getting harder. This thesis explores how to close this gap. The result of this thesis project is a prototype that provides the missing technological link between an alerting systems and modern smart devices. An eventual product should support all kinds of services, but the prototype is limited to solving the problem of connecting an alerting system to a modern total conversation telephones. The prototype was evaluated and based on the evaluation data a timeline was created. An overall positive response towards the product exists and the timeline had adding more third party services (such as Skype and FaceTime) as a high priority. The complete timeline as well as adding Signal Initiation Protocol support is left as future work.

Abstract [sv]

I Sverige har antalet personer med hörselskada ökat de senaste åren. För att hjälpa de med hörselproblem finns det tre viktiga hjälpmedel: hörapparater, special telefoner och varseblivningssystem. Stora teknologiska framsteg har skett för både hörapparater och special telefoner. Hörapparater har gått från stora otympliga apparater till små nätta anordningar som man har i örat. Enkla texttelefoner är idag komplexa system som stödjer både video, ljud och text i realtid. Även fast smarta lampor och andra varseblivningsprodukter existerar så är utveckling för varseblivning speciellt gjorda hörselskadade och döva undermåliga. Gapet som skapats mellan moderna varseblivningsprodukter och varseblivning som hjälpmedel växer sig allt större. Denna rapport ska undersöka detta gap. Resultatet av detta projekt är en prototyp som tillhandahåller den teknologin som ska länka modern varseblivning och varseblivning som hjälpmedel. Den tänkta produkten kan användas för många olika tjänster men i detta projekt är den begränsad till total konversations telefoner. Prototypen har blivit utvärderad och en tidslinje, baserad på utvädringen, har skapats. Tidslinjen ska beskriva kommande tjänster och enheter som skall kunna användas tillsammans med prototypen. Det visar sig att den skapade prototypen blev positivt mottagen och att tjänster som Skype och Facetime skulle ha hög prioritering på tidslinjen.
