| Popis: | 106 The multimedia kiosk installed at the four key supermarkets in Taiwan provides various convenient services, including: payment, top-up and ticket reservation. Kiosk is usually designed with a wizard interface for new users or occasional users. Users follow the steps shown on the screen to complete the task in sequence, but interface overview and procedural flexibility are not available. Besides, incongruity of thought tends to appear when the page is in transition, and cause spatial disorientation, in turn leads to confusion during usage of the kiosk. Kiosk at the supermarket increasingly provides huge amount of services that brings benefits and drawbacks. Too many service items cause choice overload. From the viewpoint of user-centered design, reducing interaction cost and creating good user experience is the core value of enhancing interface usability. The design of the main menu of kiosk at the supermarket usually offers popular shortcut options, but the usage rate of shortcut was revealed to be low according to the investigation. This research applies progressive content disclosure, option groups, and subitizing theory to layout recommended options and main menu in different tab pages and differentiate option configurations by groups in an attempt to increase the usage rate of shortcut options. Users’ testing is conducted with the improved interface to verify its performance. According to the analysis of the testing result, this research proposes the following conclusions: (1) Applying option groups and subitizing effect to the main menu of kiosk can significantly enhance the performance of visual search. (2) Using progressive content disclosure technology to separate service options and shortcut options provided by the kiosk can effectively enhance the utilization rate of the shortcut as well as the overall usage performance. (3) Menu for each step of the single task is presented by continuous repeated dialog boxes. Users can fully control the task process as well as improve (minimize) the occurrence of broken links, spatial disorientation, and the loading of task memories caused by opening up a tab page. |
