對成年人來說，選擇保險為一重要課題。然而保險的種類多樣且保單內容繁複，這使得選擇符合自己需求的保險方案成為一項複雜的決策。以汽車險為例，一張保單中包含的資訊繁多，包括了保費、理賠金、理賠項目、理賠條件等等，而每家保險公司皆提供可讓使用者自訂保單的選項，使得保單組合數量繁多，同一家公司甚至多家公司間的多張保單之間不易比較內容，這些因素使選擇適當汽車險的決策過程繁複。當今已有類似系統如推薦系統試圖解決此一問題，然而這些系統多擁有只專注於自家保單的問題，且都以文字來呈現保單內容使得關鍵的內容如價錢、理賠金等不易一次性的大量比較。本研究提供一系統試圖解決此問題，透過將保單的內容視覺化，提供消費者比較的基礎，從而選擇出較為適合己身的方案，並透過使用者研究探討系統的效益與易用性。

Selecting the right insurance plan is a crucial decision, but the variety of options and the complexity of insurance policies can make it challenging to choose the best plan that meets individual needs. Take car insurance as an example, a single policy includes numerous details such as premiums, coverage amounts, claimable items, and claim conditions. Additionally, each insurance company offers customizable policy options, resulting in a multitude of possible combinations of insurance plans. Therefore, comparing these plans, even within the same company, can be difficult. Existing recommendation systems attempt to address this issue, but they often focus solely on a company's own policies. Moreover, they typically present policy details in textual form, making it hard to compare key aspects like price and coverage at scale. This thesis designed a system that visualizes policy details, providing a basis for consumers to compare and choose the most suitable plan. A user study is conducted to assess the system's effectiveness and usability.
