觸控式螢幕介面的使用,在日常生活中的各種電子產品的應用已非常普遍,且已廣為大眾所接受。最近這幾年流行熱門的手持式汽車導航儀(Portable Navigation Device, PND),觸控式螢幕介面更是不可或缺的必備規格功能之一。因其便利操作的直覺式觸控、互動資訊畫面的呈現、圖形化介面隱喻的提示、外觀視覺的質感與美感、高效率人性化的簡易操作,大為提升愈來愈複雜電子科技產品使用性的滿意度。
本研究目的為針對在未來生活中普及率高度成長的PND產品,以使用者對PND操作觀點,探討對於PND觸控式螢幕介面架構之各項操作模式,使用者心智模式與觸控式螢幕介面設計的關連性。依據相關使用性之介面設計文獻,從實際任務操作與理論相互驗證的方式進行研究。
研究方法為以使用者在操作三組不同形式觸控螢幕介面架構(平衡對稱圖示全功能介面A、立體大圖示意主功能式介面 B、中心圖示重點功能式介面C)任務時,測試其操作績效與互動模式主客觀感受評價,作為未來介面架構設計時之參考。研究結果說明如下:
1. 三組觸控式螢幕介面架構在操作任務時間與按鍵次數績效上之比較
(1) 基本設定的音量調整、語音警示與螢幕畫面調整設定,任務操作時間與按鍵次數績效,結果以介面架構C在基本功能設定表現最佳;而音量語音提示調整在操作按鍵次數有交互作用的產生。
(2) 進階設定導航地點登錄設定的操作時間,受測者之間的交互作用有顯著差異。
(3) 進階設定語音導航功能靜音、雙畫面切換與中止取消導航任務的操作時間與按鍵次數績效,介面架構A績效最佳。而在操作按鍵次數有交互作用的產生。
(4) 導航任務目的地設定以介面架構C對受測者的人機介面認知最容易,相對操作次數績效最好。
(5) 整體任務績效介面架構有交互作用產生。在整體任務的操作次數的表現上,介面架構C的操作次數(平均208.80次)比架構A的操作次數(平均217.60次)與架構B的操作次數(平均230.45次)少,基本三款介面架構差異不大,都在可以接受設計平均水準之上。
2. 使用者滿意度QUIS評量表分析:
(1) 操作時的學習程度,介面架構C之績效表現最差,因其操作流程與步驟不容易使用及學習。
(2) 操作時的用字及軟體資訊,介面架構 A之績效表現最好,其易於操作辨識對稱介面架構與功能術語用詞,較被受測者接受。
The use of touch sensitive screen user interface is very popular in the modern electronic products and has been widely accepted by consumers. During recent years, touch sensitive screen user interface has become a necessary attribute to most fashion portable navigation devices (PND). Because of ease of operation, direct sense of touch, interactive information image, graphic and icons usage hints, aesthetic feeling, and high efficiency humanized operation, the touch sensitive screen user interface has improved users’ satisfaction towards many complex electronic products.
The purpose of this research study is to analyze the structure of PND user interface based on touch sensitive screen interaction. For every operation mode, the relationship between user interaction stereotype and touch sensitive screen user interface design was analyzed from the point of view of usability. This research study was performed based on the actual operation and theory according to the related user interface design documents.
The research approach is to apply the User-Tool-Task mode to operate three different PND touch sensitive screen user interface (i.e., A is designed with balanced symmetrical full function icons, B is designed with large 3D primary function icons, and C is designed with central important function icons) and collect data of participant’s subjective and objective interaction satisfactions in order to use this study as a reference for designing the future PND user interface structure. The result of study is explained as follows:
1. The comparison of task time and amount of button clicks among the three groups of touch sensitive screen user interface structure.
(1) The interface with structure C is proven to have the best task time with least number of button clicks for the basic function of volume adjustment, voice warning, screen picture adjustments, and adjustment of voice guidance volume.
(2) The task time of advanced navigation location registration shows significant interaction effects among different users’ task performance.
(3) The user interface of structure A shows the best performance results regarding task time and amount of push buttons for the advanced voice navigation functions, mute, switch between screens, and cancel of navigation tasks.
(4) The user interface of structure C is found to be the easiest for users to setup or input location pertaining to navigation task.
(5) There is an interaction effect in the performance of the overall interface structure. The user performance regarding total button clicks of user interface structure C (mean= 208.80) is better than the user interface of structure A (mean= 217.60) and structure B (mean= 230.45). There is no significant difference among all the three groups of interface structures and all of them are acceptable because of reaching the required design specifications.
2. The followings are the analysis of user’s satisfaction based on the QUIS comments:
(1) The user interface of structure C has the worst performance because it’s task procedures and steps are not easy to follow and understand.
(2) The user interface of structure A has the best performance in the choice of words and software information. It is easy to operate and understand because of it’s balanced interface structure and functional terms. Most of the participants found the interface A as the most acceptable one.
