本研究的主要貢獻在於：第一，提出一套面向既有桌面應用程式的無需程式開發介面改造流程，降低使用者在無原始碼情境下調整介面的門檻；第二，設計可驗證的中介資料模型，使介面生成、原介面對應、互動同步與持久化能以統一格式管理；第三，整合 GUI 與大型語言模型工具調用，使自然語言操作能在明確邊界內執行，並與手動編輯保持一致；第四，整理並實作非侵入式介面改造框架所需的穩定性機制，使改造結果能被檢查、保存與重新開啟。論文並以互動成本、介面改動成本與組織交付週期作為評估面向，說明 UI Transformer 對既有應用程式介面改善的適用範圍。;Modern software usage scenarios evolve rapidly， and users increasingly need interfaces that better match their workflows， information structures， and operational habits. However， many existing applications remain difficult to modify because their source code is unavailable， extension mechanisms are limited， or redevelopment and migration are too costly. Conventional approaches such as vendor feedback， API-based extension， plug-in development， robotic process automation， or full redevelopment often depend on technical expertise， organizational resources， and explicit support from the original software， making them insufficient for everyday interface refactoring needs of non-developers.
This thesis addresses the dilemma between interfaces that no longer fit users′ needs and the high cost of modifying existing applications. When users lack source code， vendor-supported extension mechanisms， or programming expertise， interface adjustment needs are difficult to turn into usable and maintainable results. In response， this thesis proposes UI Transformer， a programming-free Legacy UI Transformation framework that combines Venom technology with LLM-based assistance. The framework provides an operable， verifiable， and persistent transformation workflow under three constraints: no modification of the existing desktop application， no reliance on vendor-provided Plug-In mechanisms， and no programming requirement for users. Built on Venom′s Non-Invasive Interface Extension capability， UI Transformer creates an editable interface layer above an existing application and turns a developer-oriented extension process into an End-User workflow that combines graphical editing with natural-language instructions.
The contributions of this work are fourfold. First， it proposes a programming-free workflow for transforming existing desktop application interfaces under no-source-code constraints. Second， it designs a verifiable intermediate data model that unifies interface generation， mapping to the original application， interaction synchronization， and persistence. Third， it integrates GUI editing with LLM Tool Invocation so that natural-language operations remain bounded and consistent with manual edits. Fourth， it implements stability mechanisms that allow transformation results to be inspected， saved， and reopened. The thesis further uses interaction cost， interface-change cost， and organizational delivery lead time as evaluation dimensions to clarify the applicability of UI Transformer for improving existing application interfaces.
