To study the ease of use of T-shirt customization web GUI, three websites that provide T-shirt customization services were selected to analyze the current status of T-shirt customization websites. Through prior research, we establish the evaluation principle as consistency and clarity, operability, feedback, coping with errors, sharing and ease of search. Based on this, the T-shirt customization web GUI design guidelines were drafted and three delphi surveys were conducted on GUI-related experts to prove the validity of the web GUI guidelines evaluation items that are effective in customizing T-shirts. This study is expected to contribute to increasing the production and usability of the T-shirt customization web and to be used as an effective reference for customization web GUI design.

Table 6. T-shirt customization Web GUI guideline assessment item draft Number GUI guideline assessment item draft Provides tutorials for custom methods, features, and 1 location descriptions. Restrict custom work views to 'front', 'back', 'side', 'back 2 of neck'. Center the task screen, right for the detailed editing 3 tool, and left for the custom tool. Custom tools are represented by simple titles and icons, 4 but should be recognizable to anyone. For sub-icon without text, hover the mouse cursor over 5 the letter to provide a functional description. Provide custom sub-editing tools classified according to Consist 6 their function. ency Provides instant screen transformation without the use and 7 of flamboyant interaction. clarity Provide the same type of GUI for various browsers and 8 operating systems. Overall, provide menus, colors, and fonts in a consistent 9 format. Emphasize the information that is important for 10 customization through visual elements. Follow the customization methods in order so that users 11 can understand the customization. Clearly categorize and mark the categories of custom 12 and editing tools by color. Provide achromatic background so that you can be 13 realistic about your custom. 14 Make it possible to store customized work done by the user. Do one thing at a time rather than multiple 15 customizations at the same time. Operabi Provide layer functionality to facilitate selection and 16 lity editing of each design source. Separate work screens and other areas and provide 17 space for users to place files to edit. 18 Allow users to set the location of frequently used features as desired. Feedba ck Handlin g Errors Ease of sharing and retrieva l Customized tools tailored to user settings should be automatically saved for future use. A simple function of the custom function should enable the use of shortcuts. The correct completion button for the work activity must be pressed to complete it. It should be disabled and shown even if the function is not available rather than just showing the custom functions available. Numerical inputs should be used to enable accurate work. 24 The custom work screen should be able to be enlarged Screen augmentation allows for all available formats, such as buttons and scrolls. To avoid custom errors, the size and number of characters in the custom area should be limited. The number of characters that can be pre-populated should be indicated to prevent users from modifying them during the operation. It should be possible to check the current customization process. It provides a preview of the functionality of the custom tool as an example GIF screen. Except for the categories of tools that the user is using, the remaining tools should be grouped and hidden. It should clearly distinguish between tasks in progress and those that are not. Depending on the user's mouse cursor, the color of the selection tool should be changed. The last activity the user worked on should be changed to the top of the layer in real time. When finished customizing, guide them to the next step. The interface should be automatically modified according to the user's operation. When changing the product during customization, the customization work that was carried out should remain the same. There should be an automatic storage function so that the work that has been carried out can be recovered even if it fails. Q&A or counseling should be possible to solve the user's cognitive errors. You should be able to refer to the help according to your needs. A save pop-up window should be provided to prevent user exit errors. The program should inform the user about the user's error. The customization of the user should be provided in the most realistic representation. Custom files should be converted to match the format of various SNS. It should be possible to upload customizations to the site and to save them as files by individuals. Custom files that you want to refer to should be imported into the user's custom. Users should be able to introduce their customizations through hashtags. It should store other people's customizations and provide them for users to edit. 티셔츠커스터마이징웹 GUI 디자인가이드라인평가항목초안은총 47개의항목으로일관성및명료성항목은 13개, 조작성항목은 10개, 피드백항목은 12개, 오
