Users may face challenges while designing graphical user interfaces, due to a lack of relevant experience and guidance. This paper aims to investigate the issues that users with no experience face during the design process, and how to resolve them. To this end, we conducted semi-structured interviews, based on which we built a GUI prototyping assistance tool called GUIComp. This tool can be connected to GUI design software as an extension, and it provides real-time, multi-faceted feedback on a user's current design. Additionally, we conducted two user studies, in which we asked participants to create mobile GUIs with or without GUIComp, and requested online workers to assess the created GUIs. The experimental results show that GUIComp facilitated iterative design and the participants with GUIComp had better a user experience and produced more acceptable designs than those who did not.

GUIComp：具有实时、多方面反馈的 GUI 设计助手

由于缺乏相关经验和指导，用户在设计图形用户界面时可能会面临挑战。本文旨在调查没有经验的用户在设计过程中面临的问题，以及如何解决这些问题。为此，我们进行了半结构化访谈，在此基础上我们构建了一个名为 GUIComp 的 GUI 原型制作辅助工具。该工具可以作为扩展连接到 GUI 设计软件，它可以对用户当前的设计提供实时、多方面的反馈。此外，我们还进行了两项用户研究，其中我们要求参与者在有或没有 GUIComp 的情况下创建移动 GUI，并要求在线工作人员评估创建的 GUI。
