  • Abstract In our lives, much of the information we receive is transmitted via sound. People with hearing impairment, however, are unable to acquire sound messages because of their disabilities. They need technological aids to help them receive information, and information receiver is one of such aids.
    Among the information receivers available on the market, some are for single message reception and some are for multiple message reception. The reception modes include vibration mode and flash mode. Yet we have rarely seen discussions on whether these messages are needed by people with hearing impairment, or whether they are able to distinguish the messages, or whether the receiving and wearing modes are appropriate. This study therefore explores the problems above in order to design an information receiver that enables people with hearing impairment to identify the messages correctly.
    Following analysis of current situations, 30 people with hearing impairment who are 20 years of age or older were selected as subjects. Questionnaire survey was first performed to obtain their basic information, the extent to which they need important information, and their requirement for information receiver. Through one-mean t-tests and one-way ANOVA, nine significant requirements were identified. Afterwards, two stages of questionnaire surveys were conducted: “icons used to represent the information requirements” and “Others by which the signal lights, icons and labels on the interface of information receiver are arranged.” Through Friedman test and t-test, the researcher identified the matching icons of the nine messages and finalizes the order by which the signal lights, icons and labels are laid out from left to right on the interface of the information receiver.
    Based on the outcome of the questionnaires, the researcher made a model that demonstrates message display by cellular phone and a working model of the information receiver. During the experiment stage, the operational responses of the two devices placed at the waist and at the back pocket were examined. Data were collected by following four variables: information identification accuracy, message reception response time, operational easiness evaluation and operational preference evaluation. Experiment outcomes indicated that the information identification accuracy rates of both cell phone and information receiver were close to 100%, that there is no significant discrepancy between both products in terms of operational easiness and operational fondness. Wearing product on waist was more preferred than on back pocket, and had shorter response time and easier operation evaluation. 
    Research findings can serve as references for designing information receivers for people with hearing impairments in the future, make up for the deficiency of hearing aids, help improve the living quality of people with hearing impairments and develop a barrier-free living environment.
