年輕視障者觸覺資訊處理模型建構及其生活產品設計研究

Tactile information processing model (TIPM) of the young visually impaired and life product design study

人們藉由視覺感官的辅助可以順利地操作產品，然而，視覺障礙者因缺乏視覺感知能力，則需倚靠其他的感官，例如简覺。在這個研究中，主要在探討視覺障雖者透過觸覺操作產品時的行為特徵，並經由實驗進而建構出以視覺障贼使用者為中心的附覺資訊處理模型（TIPMI）。在實驗中，7位視障者被邀請進行三項產品的使用，這三項產品包括有保溫瓶、傳統审話及智慧觸控手機產品。研究結果指出，在任務完成時間中，實體化介面導向的產品明顯優於平面化簡控介面導向的產品。實體化介面導向的產品有明顯的物件特徵，能輔助視障者進行相關產品操作任務。相對地，平面化觸控介面導向的產品則無明顯特徵，視障者需透過特殊的語音介面的提示進行任務操作。綜合以上研究結果，本研究歸納出視障使用者為中心的覺資訊處理模型（TIPM）。這個研究結果將有助於相關視障輔具產品的設計發展。

People can operate the product smoothly with the aid of visual senses. However, visually impaired people need to rely on other senses because of lack of visual perception. In this study, experiment was mainly to explore the behavioral characteristics of visually impaired people when they manipulated products through touch. Through experiment, a tactile information processing model (TIPM) centered on visually impaired users was constructed. In Experiment, seven visually impaired people were invited to use three products, including thermos, traditional phones and smart touch phones. The results showed that the entity interface-oriented products are significantly better than the flat interface-oriented product in the mission completion time. The entity interface-oriented products have obvious object features that can assist the visually impaired to perform related product operation tasks. In contrast, the products that are oriented by the flat-touch interface have no obvious features, and the visually impaired people need to perform the operation task through the prompt of the special voice interface. Based on the above findings, this study summarized a tactile information processing model(TIPM) centered on visually impaired users. The results of this study will contribute to the development of related visually impaired assistive products.
