smARt way: a mobile smart assistant to help users navigate indoors

在机场、火车站、医院、购物中心和大型超市等大型基础设施内导航一直都是具有挑战性的，特别是对初次访问的游客来说。经典但效率低下的室内导航解决方案包括目录地图和信息板。增强现实(AR)可以使室内导航变得直观和强大。通过智能手机的视角显示呈现在物理空间上的虚拟指南，用户可以更自然地点对点地引导，而不是通过将地图与他们周围的环境进行比较。AR导航是一种从用户角度工作的创新解决方案，可用于室内(和室外)解决方案。我们的系统由一个移动组件(例如智能手机应用程序)组成，它将实时智能以方向和定位信息的形式覆盖在通过移动设备(例如智能手机)的摄像头所看到的现实之上。有了第一人称视角，就不再需要将地图与现实世界相匹配才能到达目的地。此外，任何语言负担都被解除，用户可以独立导航到他们的目的地。该工具适用于残疾人，通过语音帮助和触觉技术引导他们通过轮椅无障碍路线。此外，该工具可以在紧急情况下快速安全地疏散大型公共空间。我们开发了一种基于人工智能的主动多目标路径算法；例如，可以通过预测入住率来避开拥挤的地方，并通过最大化社交距离的路线引导用户到达目的地。我们可以引入本地化的营销系统，在导航到目的地的同时，以AR内容的格式宣传机场的不同设施，如商店和餐馆。我们还可以与其他公司合作，如果用户中途停留时间较长，我们还可以推荐短途城市旅游。后台服务器将处理上述所有流程，这些流程可以与机场内部管理系统相结合，以通知中转旅客他们的下一个登机口。

Navigating inside big infrastructures such as airports, train stations, hospitals, shopping malls, and large supermarkets has always been challenging, specifically for first-time visitors. Classic, yet inefficient, indoor navigation solutions include directory maps and information boards. Indoor navigation can be made intuitive and powerful with augmented reality (AR). By showing virtual guides rendered on physical space through the view of a smartphone, users can be directed point to point more naturally than by comparing a map to their immediate surroundings. AR navigation is an innovative solution that works at users' perspective and can be utilized for indoor (and outdoor) solutions. Our system consists of a mobile component (e.g., smartphone app) which overlays real-time intelligence in the form of directions and localized information on top of the reality seen through the camera of mobile device (e.g., smartphone). Having the first-person perspective, it is no longer necessary to match a map to the real world to get to a destination. Furthermore, any language burden is lifted and users can independently navigate to their destination. This tool is suitable for people with disabilities by guiding them through wheelchair accessible routes using voice help and haptic technology. Moreover, this tool offers fast and safe evacuation of large public spaces in case of an emergency.We have developed an AI-based proactive multi-objective routing algorithm; for instance, crowded places can beavoided by predicting occupancy and users can be guided to their destinations through routes that maximize social distancing. We can introduce a localized marketing system which advertizes different amenities at the airport, such as shops and restaurants, in the format of an AR content while navigating to the destination. We can also partner with other companies and suggest short city tours if the user has a long layover. The backend server will handle all the aforementioned processes which can be coupled with the internal management system of the airports to inform transit passengers about their next gate.
