摘要


目前,互動觸控技術之發展快速,造成很多的企業或是學生皆想以此為基礎做創作技術或研究發展。若以互動為基礎來研發新產品是可行之作法,但在實際執行上之困難度以及成本還是有很大的限制。對於面對使用低成本觸控介面架設技術來說,在技術上當需要製作研究機台或是工作檯面時,卻仍需花費大量時間來製作與架設。根據文獻得知,良好之互動平台需具備快速架設以及靈敏操作之特性。因此本研究針對在架設觸控平台時所需解決之觸控靈敏度的問題,加以探討與研究。 根據文獻之分析在觸控辨識之影響因素,並配合專家之訪談確立影響因素為接觸觸控面、投影機投射亮度、投光器照射方式、環境光源以及軟體曝光度等五項要素。並實際製作互動桌觸控介面平台,以研究各項影響因素對於互動觸控介面之影響性。為求瞭解此五項要素對於互動觸控桌靈敏度之影響,以此五項因素做為自變項,並以文獻得知之觸控靈敏度效標任務執行速度與辨識錯誤率做為依變項。並以立意抽樣法針對20位目標樣本進行研究實驗,分析得知在五項變項上以軟體曝光度之中等亮度(R190.G190.B190.軟體內設置)為主,配合投光器投光方式以均勻照射觸控檯面之方法,可達到對於依變項任務花費時間及錯誤性之顯著性,並可達到對於互動觸控桌之靈敏度的提升。也得知觸控面之種類雖對靈敏度無直接之提升,但在使用上霧面之接觸面可對使用者帶來較小之負擔。而投影機亮度部份則是以使用者能清楚辨認投影資訊之亮度為主。在環境光源部份則得知應以防範紅外線之環境光為主要影響因素。

At present, the rapid development of interaction technology makes many enterprises or students want to create some technology or to study some development on the basis of it. Although taking interaction as a foundation to develop new productions is acceptable; however, the difficult of practical enforcement and cost are still a long way to go. As far as using low-cost touch interface constructor is concerned, when making search machines or working tables technically, it still takes an amount of time to make and to set. According to records, good interaction platforms are equipped with rapid set-up and sensitive operation. Therefore, this research is aimed at solving the problems of touch sensitive while setting up a touch platform, and also at studying. In terms of records analyses, knowing some influential conditions of touch recognition and experts’ conversations, this research acquires five main factors:touch interface、projector light、the way IRLED illuminates、environment illuminant and software EV, and also makes interaction table of touch interface platforms practically to study every influential factor with regard to the effective ways of interaction table of touch interface. In order to understand the influences of these five main elements with regard to interaction table of touch interface sensitivity, this research takes these five factors as independent variables as well as takes time-consuming and error rate as dependent variables. This research takes 20 people as samples on purposive sampling way to study the experiment and know that the five variables are based on the medium light of software EV (R190.G190.B190.software set inside), and cooperates with IRLED lighting tables of touch interface even to reach the significance of dependent variables of task time-consuming and error times, and to reach the promotion of sensitivity of interaction tables of touch interface. This research understands that contacting with the touch interface shows no direct promotion of sensitivity, but that matt surface tables could bring the users smaller burden. The projector light could make users clearly distinguish projected information. As for the environment illuminant, this research shows that the main influential course is to prevent ultra red rays.
