在本文中，我们介绍了第一个模拟框架，该框架提供了成本效益的手段来评估不同用户群的室内导航系统（例如，具有视觉障碍的用户）、各种定位技术和导航指令算法。模拟引擎使用Unity游戏引擎，该引擎跟踪虚拟环境中的虚拟用户交互和运动，该虚拟环境表示用户导航的物理环境。该框架包括以下模块，将由室内导航系统开发人员定义：1）定位模块，模拟室内定位技术及其观测精度; 2）使用自然语言短语生成导航指令的室内导航算法模块，以及3）包括能够理解导航指令的人类感知和信息处理的虚拟用户模型（VUM），感知周围的环境，并根据这些信息采取行动。该框架还包括一个性能分析模块，该模块根据导航成功率和路线相似性来评估室内导航系统的性能。
In this paper, we introduce the first simulation framework that provides cost-effective means to evaluate indoor navigation systems for different user groups (e.g., users with visual impairment), various positioning techniques, and navigation instructions algorithms. The simulation engine uses the Unity game engine, which tracks the virtual user interaction and motion in a virtual environment that represents the physical environment in which the user navigates. The framework includes the following modules that will be defined by the indoor navigation system developers: 1) Positioning module which simulates indoor localization techniques and their observed accuracy; 2) Indoor navigation algorithm module that generates the navigation instructions using natural language phrases, and 3) Virtual user model (VUM) that includes human perception and information processing that can understand navigation instructions, perceive the surrounding environment, and act based on this information. The framework also includes a performance analysis module that evaluates the indoor navigation system performance in terms of navigation success rate and route similarity.
