The military backpack used by the infantry imposes the greatest load on the body and, thus, is also the cause of most user complaints. This study (1) establishes a systematic development procedure for a military backpack that reflects user opinion; (2) suggests a usability questionnaire tool that can identify realistic user needs; and (3) proposes usability verification experiments that can quantitatively measure the usability of the military backpacks. The military backpack development procedure was created in accordance with user‐centered design principles. The “context of use” of the military backpack was extracted from a literature review and interviews with experts and actual users. In addition, the usability questionnaire tool and usability verification experiments were devised based on the identified context of use. An analysis of the usability questionnaire answered by 100 infantry soldiers confirms that the region of pain felt by users varies on the size of the human body. Thus, it was possible to recognize the necessity of diversifying the specification of the military backpack. The usability verification experiments did not produce statistical results because only four infantry soldiers performed the pilot test, but the applicability and effectiveness of the proposed experiments could be confirmed through this pilot test. The seven proposed experiments are expected to help confirm the usability differences among different military backpacks or body sizes. The military equipment development procedure, usability evaluation tool, and usability verification experiments are expected to improve user satisfaction and military operations when applied to the development of various military supplies.

基于“使用环境”的韩国军用背包可用性评估

步兵使用的军用背包在身体上施加了最大的负担，因此也是大多数用户抱怨的原因。这项研究（1）为反映用户意见的军用背包建立了系统的开发程序；（2）提出了一个可用性问卷调查工具，可以识别现实的用户需求；（3）提出了可用性验证实验，可以定量测量军用背包的可用性。军用背包的开发程序是按照以用户为中心的设计原则创建的。军事背包的“使用背景”摘自文献回顾以及与专家和实际用户的访谈。此外，基于确定的使用环境，设计了可用性调查表工具和可用性验证实验。对由100名步兵回答的可用性问卷进行的分析证实，用户感到的疼痛区域随人体大小而变化。因此，可以认识到使军用背包的规格多样化的必要性。可用性验证实验没有产生统计结果，因为只有四名步兵进行了试点测试，但是通过该试点测试可以证实所提议实验的适用性和有效性。提出的七个实验有望帮助确认不同军用背包或身体尺寸之间的可用性差异。军事装备开发程序，可用性评估工具，
