聽障者資訊接收器之設計研究
A Study and Design on the Information Receiver for Individuals with Hearing Impairment
摘要
生活中有許多訊息是靠聲音來傳遞的，而聽障人士則因其障礙而導致無法輕易獲取這些聲音訊息，必須藉由科技輔具來協助接收資訊，訊息接收器就是其中之一。 然而目前市面上的訊息接收器有些是單一訊息的接收，有些是多訊息的接收，其接收模式有震動模式或閃光模示，至於這些訊息是否為聽障者所需求的，或是能否分辨出是何種訊息，以及接收和佩戴模式是否適合，卻少見探討，本研究即針對以上問題進行探討，以設計出讓聽障者能正確辨識訊息的訊息接收器。 在現況分析後，以 30 位年滿 20 歲的聽障人士為受測者；先以問卷來調查聽障者的需求，經由獨立 t 檢定和單因子變異數分析得出電話鈴響通知、手機鈴聲通知等 9 項重要需求；之後進行「訊息需求代表的圖像」及「訊息接收器介面的訊號燈、圖像、文字排列方式」兩階段問卷調查，所得資料運用 Friedman 檢定和獨立 t 檢定得出這 9 項訊息需求所配對的圖像，及確立警示燈、圖像、文字由左至右排列在接收器介面上的順序。 根據問卷結果，製作出用手機顯示訊息和訊息接收器可操作之模型，於實驗階段中，實測此兩項產品置於腰間及置於後方口袋時的操作反應。結果顯示無論是手機或訊息接收器的訊息辨識正確率都接近 100%；兩項產品的操作難易度和喜好度沒有顯著的差異；產品置於腰間為較佳的佩戴位置，有較短的反應時間及較容易操作的特性。 研究結果可做為往後聽障者訊息接收器的設計參考，以彌補聽力輔具的不足，達到提高聽障者的生活品質的目標，進而發展成無障礙的生活環境的理想。

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.
