“…Clew demonstrated the potential of using AR toolkit to localize blind users on a prerecorded route with acceptable accuracy [92]. Verma et al [90] reported that an AR-based navigation system could provide a better user experience than traditional 2D maps. Brata et al [28] found that sighted participants rate 2D digital map over a location-absed AR interface for efciency and dependability, but AR interface over 2D digital map for hedonic qualities and overall performance.…”

Remote sighted assistance (RSA) has emerged as a conversational assistive service, where remote sighted workers, i.e., agents, provide real-time assistance to blind users via video-chat-like communication. Prior work identifed several challenges for the agents to provide navigational assistance to users and proposed computer visionmediated RSA service to address those challenges. We present an interactive system implementing a high-fdelity prototype of RSA service using augmented reality (AR) maps with localization and virtual elements placement capabilities. The paper also presents a confederate-based study design to evaluate the efects of AR maps with 13 untrained agents. The study revealed that, compared to baseline RSA, agents were signifcantly faster in providing indoor navigational assistance to a confederate playing the role of users, and agents' mental workload was signifcantly reduced-all indicate the feasibility and scalability of AR maps in RSA services.

“…The communications positioning technologies used in our smartphone, known as a GPS or global navigation satellite system (GNSS) [26], do not work effectively inside the home or in the areas covered by trees or surrounded by concrete buildings. Presently, to achieve indoor positioning are using wireless technologies such as wireless local area network (WLAN) [27], Bluetooth [28], near field communication (NFC) [29], Ultrasound [30], Infrared [31], and radio frequency identification (RFID) [32]. A comparison among the communication technologies is shown in Table 1.…”

<p><span lang="EN-US">Augmented reality overlays virtual content on the physical world, displaying location-based information more efficiently. Tracking is a trace detail of the location recorded, either by taking a reading based on a set time interval, set distance, and change in direction by more than a certain angle, or a combination of these. Tracking is divided into two types, outdoor tracking, and indoor tracking. Augmented reality added value and information to tracking applications, whether indoor or outdoor. Recently, outdoor tracking by the global positioning system (GPS) became an essential component in navigation applications. However, indoor tracking is still challenging in the augmented reality field. Most augmented reality indoor tracking use optical and sensor-based tracking, such as markers, beacons, Raspberry Pi, and route planner modules for the building. With the technology enhancement, indoor tracking started to rely on WiFi, Bluetooth, geographic information system, radiofrequency identification, and sensor chip technologies. Our paper describes the recent augmented reality tracking techniques from 2011 to 2021. The paper compares image detection algorithms with various communication technologies, disscusing the advantages and the limitations of each technology.</span></p>

Remote sighted assistance (RSA) has emerged as a conversational assistive technology, where remote sighted workers, i.e., agents, provide real-time assistance to users with vision impairments via videochat-like communication. Researchers found that agents' lack of environmental knowledge, the difficulty of orienting users in their surroundings, and the inability to estimate distances from users' camera feeds are key challenges to sighted agents. To address these challenges, researchers have suggested assisting agents with computer vision technologies, especially 3D reconstruction. This paper presents a high-fidelity prototype of such an RSA, where agents use interactive 3D maps with localization capability. We conducted a walkthrough study with thirteen agents and one user with simulated vision impairment using this prototype. The study revealed that, compared to baseline RSA, the agents were significantly faster in providing navigational assistance to users, and their mental workload was significantly reduced -all indicate the feasibility and prospect of 3D maps in RSA.
