Advancements in IoT technology have been instrumental in the design and implementation of various ubiquitous services. One such design activity was carried out by the authors of this paper, who proposed a novel cloud-centric IoT-based disaster management framework and developed a multimedia-based prototype that employed real-time geographical maps. The multimedia-based system can provide vital information on maps that can improve the planning and execution of evacuation tasks. This study was intended to explore the acceptance of the proposed technology by the specific set of users that could potentially lead to its adoption by rescue agencies for carrying out indoor rescue and evacuation operations. The novelty of this study lies in the concept that the acceptability of the proposed system was ascertained before the complete implementation of the system, which prevented potential losses of time and other resources. Based on the extended Technology Acceptance Model (TAM), we proposed a model included factors such as perceived usefulness, perceived ease of use, attitude, and behavioural intention. Other factors include trust in the proposed system, job relevance, and information requirement characteristics. Online survey data collected from the respondents were analyzed using structural equation modelling (SEM) revealed that although perceived ease of use and job relevance had significant impacts on perceived usefulness, trust had a somewhat milder impact on the same. The model also demonstrated a statistically moderate impact of trust and perceived ease of use on behavioural intention. All other relationships were statistically strong. Overall, all proposed relationships were supported, with the research model providing a better understanding of the perceptions of users towards the adoption of the proposed technology. This would be particularly useful while making decisions regarding the inclusion of various features during the industrial production of the proposed system.
物联网技术的进步在各种普及服务的设计和实施中起到了重要作用。本文作者开展了一项这样的设计活动，提出了一种新颖的基于云的物联网灾害管理框架，并开发了一个基于多媒体的原型，该原型采用了实时地理地图。基于多媒体的系统可以在地图上提供重要信息，从而改善疏散任务的规划和执行。本研究旨在探索特定用户组对拟议技术的接受程度，这可能导致救援机构采用该技术进行室内救援和疏散行动。这项研究的新颖之处在于，在完全实施系统之前，就确定了拟议系统的可接受性，从而避免了潜在的时间和其他资源损失。基于扩展的技术接受模型（TAM），我们提出了一个包含感知有用性、感知易用性、态度和行为意向等因素的模型。其他因素包括对拟议系统的信任、工作相关性和信息需求特征。从受访者那里收集的在线调查数据使用结构方程建模（SEM）进行分析，结果表明，尽管感知易用性和工作相关性对感知有用性有显著影响，但信任对感知有用性的影响略弱。该模型还表明，信任和感知易用性对行为意向具有统计上适度的影响。所有其他关系都是统计上较强的。总体而言，所有提出的关系都得到了支持，研究模型为用户对采用拟议技术的看法提供了更好的理解。这在决策是否包含各种特征以在拟议系统的工业生产中进行时特别有用。
