本研究探討以低認知負荷為導向的應用程式設計，開發一項科技解決方案，以協助性格內向或社交保留型個體，在參加活動時獲得陪伴。由於此類個體害怕被評價、社交焦慮與認知負荷等社會障礙，難以獨自參與社交活動，而現有平台多需使用者高度互動與投入，往往增加其參與困難。
本研究以符號互動論、社會交換理論與認知負荷理論為理論基礎，採用混合方法研究設計，結合準實驗（100 份有效問卷）與質性訪談（18 名受訪者）。研究測試兩種原型應用程式：原型 A（高認知負荷）與原型 B（低認知負荷）。結果顯示，原型 B 在認知負荷（3.51/5）、可用性（4.34/5）及使用者體驗（4.29/5）等面向皆獲得較高評價。質性結果亦顯示，簡潔性、可預測性及低社交壓力，有助於提升使用者的社交信心與可用性。研究所得建議設平台設計策略，應在開發目標與使用便利性之間取得平衡，重視使用者的情緒舒適性與降低負擔。

This study explores the development of a technological solution to support socially reserved
individuals in attending events with companionship, focusing on a low-cognitive-load, app-based
approach. Social barriers, such as fear of judgment, social anxiety, and cognitive overload, often
discourage individuals from participating in social events independently, while existing platforms
require extensive social engagement and effort. Guided by social theories including Symbolic In-
teractionism, Social Exchange Theory, and Cognitive Load Theory, this research adopts a mixed-
method approach combining a quasi-experiment (100 valid responses) and qualitative interviews
(18 participants). Two app prototypes were tested: high cognitive load (Prototype A) and low cog-
nitive load (Prototype B). Findings demonstrate that a low-cognitive load interface of Prototype B
achieved higher ratings in cognitive load (3.51/5), usability (4.34/5), and user experience (4.29/5).
Qualitative findings reinforced that simplicity, predictability, and low social pressure enhance so-
cial confidence and usability for socially reserved individuals, suggesting design strategies that
balance platform goals and usability with emotional ease.
