| Summary: | 碩士 === 國立成功大學 === 工業設計學系碩博士班 === 94 === As multimedia system is invited into family, the most natural operation mode is to operate freely without any objects and controllers , by using an user’s limbs as port tool to input . The existing signs distinguishing technology is becoming more and more mature. In the future , Since the possibility of developing trend of signs distinguishing technology has improved greatly, we chooses family audiovisual multimedia system as researching objective, and carry out research of signs on the development and design of operation port.
Design and assessment have been done by this research on the development of signs. First , the documents of cognitive and visional signs are collected ，then vocabulary orders that can be developed to be signs are chosen out through questionnaire of usage. The analytical forms of signs are made out through experts ' discussion ，which gave birth to signs by combing the principle of visional signs with dactylology . There are three signs modes , named likeness, indication and symbol，at last, signs that fit general users are found out through experimental assessment carried out on the relationship between the analytical methods of learning , subjective assessment and quantization with factors ，which are offered to be reference basis for future designers when they are designing home audiovisual multimedia ports.
This achievement found out a precedence of the three modes, which has the trait that in learning section, likeness ranks best , symbol second and indication style worst on learning effect ; likeness has least obscure degree, symbol second and indication has most obscure degree in obscure section; likeness is the best, symbol next to it and indication the worst in objective assessment section. On quantization , by generally looking, both items of [arms’ position] and [ palm direction] can be said to be the decisive item that affects objective assessment. On assessing the relationship among factors, we found out that testees’ likes for signs would directly affect the times of signs mistakes. At last, through Visual Basic, a checking process has been designed out, with a result that shows on the operation of cognition of single hand or double hands people who have learned signs have no obvious difference from those who haven’t learned , from that we can find out the basically developing principle of signs can be made by combining visional signs with dactylology, which can become signs that comply with the cognition and intuition of general users by designers’ creation and design.
