科技可以改變人類的生活方式，線上購物的使用人數逐年上升。線上購物平台採用產品圖搭配文字說明來介紹商品，因此產品顯示的選用是影響使用者購買意願的重要因素。
本文利用高腳杯和其螢幕顯示之參數設計提出一套方法，並在產品設計及顯示型態設計的階段以實驗來評估消費者的喜好度，並以實例來說明整個流程。首先，將參數設計應用在高腳杯設計上，利用可調整凸輪的運動方程式來設計高腳杯外型。可調整凸輪的運動方程式具有參數設計的優點，藉由調整單一參數可得到不同的運動曲線，作為高腳杯的造型投影曲線，並探討參數改變對消費者的喜好度的影響。螢幕顯示兩個高腳杯的組合圖，根據型態合成規則的規範依次進行：頁面樣式，選擇高腳杯外型，高腳杯組合樣式，觀測角度，得到兩個高腳杯顯示組合圖。以上合成過程以參數來控制，不同參數組合對應到不同的顯示組合圖。挑選16張高腳杯顯示組合圖，將高腳杯顯示組合圖放在頁面左上角的位置。設計實驗探討16張高腳杯顯示組合圖對消費者的喜好度、視覺吸引力及視覺平衡的影響，作為購物平台頁面的設計參考。

Technology can change the way people live, and the number of users of online shopping is increasing year by year. Online shopping platforms use product images and text descriptions to introduce products, so the choice of product display is an important factor that affects users' purchase intentions.
This article proposes a set of methods for the parameter design of the goblet and its screen display, and uses experiments to evaluate consumer preferences during the product design and display design stages, and uses examples to illustrate the entire process. First, the parameter design is applied to the design of the goblet, and the shape of the goblet is designed using the motion equation of the adjustable cam. The motion equation of the adjustable cam has the advantage of parameter design. By adjusting a single parameter, different motion curves can be obtained, which are used as the modeling projection curve of the goblet, and explore the impact of parameter changes on consumer preferences. The screen displays the combination diagram of the two goblets, which are carried out in sequence according to the specifications of the type synthesis rules: page style, selection of goblet shape, goblet combination style, observation angle, and two goblets display combination diagram. The above synthesis process is controlled by parameters, and different parameter combinations correspond to different display combinations. Select sixteen goblet display combination pictures, and place the goblet display combination pictures in the upper left corner of the page. The design experiment explored the influence of sixteen goblet display combination pictures on consumers' preference, visual appeal and visual balance, as a reference for the design of shopping platform pages.
