RASSAR: Room Accessibility and Safety Scanning in Augmented Reality
Abstrak
The safety and accessibility of our homes is critical to quality of life and evolves as we age, become ill, host guests, or experience life events such as having children. Researchers and health professionals have created assessment instruments such as checklists that enable homeowners and trained experts to identify and mitigate safety and access issues. With advances in computer vision, augmented reality (AR), and mobile sensors, new approaches are now possible. We introduce RASSAR, a mobile AR application for semi-automatically identifying, localizing, and visualizing indoor accessibility and safety issues such as an inaccessible table height or unsafe loose rugs using LiDAR and real-time computer vision. We present findings from three studies: a formative study with 18 participants across five stakeholder groups to inform the design of RASSAR, a technical performance evaluation across ten homes demonstrating state-of-the-art performance, and a user study with six stakeholders. We close with a discussion of future AI-based indoor accessibility assessment tools, RASSAR’s extensibility, and key application scenarios.

Planning the placement of furniture in a room is an important planning process, with proper planning, the placement of furniture can be more efficient in the use of space, as well as from an aesthetic point of view. During this time the process can be done by using a sketch or other manual method. In this research, we use augmented reality technology to plan furniture placement in a room. We use the Markerless technique in the implementation of this AR system, and use the Simultaneous Localization and Mapping (SLAM) technique to determine the geospatial point where the furniture will be the desired layout. The results of this application ifound that good minimum distance in detecting SLAM on the ground is 60 cm and can only be seen up to a maximum position of 45 ° from the Z axis of the camera’s initial position when tracking. This application runs on the Android mobile platform Introduction.

This paper presents the development of Augmented Reality (AR) for smart campus urbanization using library as the environment for the demonstration of the AR prototype. The main goal of the AR development is to help users to get information and direction easily using AR based mobile application when walking inside the library. In normal circumstances, users typically walk around and explore the library area before reaching their targeted destinations. Depending on the library size and number of reading corners, exploration and walking in the library can be time consuming. Therefore, an AR technology is introduced in this paper to improve the user experience inside the library in the right direction and information instantly. This application is developed using Vuforia software to set the image marker-based and process the output into Unity3D software, Android Studio for the Main Menu interface and IBM Watson for voice recognition. The final form of the application is successfully generated from the development of Augmented Reality (AR) application for the smart campus by using a library for the demonstration of the AR prototype. A series of application tests are conducted in each corner of the library to evaluate the effectiveness of developed AR.

The purpose of this research is to visualize furniture objects from a catalogue using a markerless augmented reality tracking. Augmented reality is applied to help customers to envision an augmented object for learning the product knowledge of the furniture chosen. The markerless tracking method used in this research is a Simultaneous Localization and Mapping (SLAM), where a targeted surface of the floor for an augmented object can be determined in certain areas in the real world without using a marker. Testing was performed with parameters such as with a minimum of lighting intensity from without lighting, low lighting and bright lighting, a minimum of distance from 50 cm, 100 cm, and 150 cm, a minimum of height from 60 cm,120 cm,160 cm, and a minimum of angle from 30,50 and 70 degree of detection from the surface of the floor. The result of this research is the Simultaneous Localization and Mapping method is confirmed to be adequate for visualizing the 3D furniture model on targeted the surface of the floor without markers.

Augmented Reality (AR) is a technology superimposing interactional virtual objects onto a real environment. Since the beginning of the millennium, AR technologies have shown rapid growth, with significant research publications in engineering and science. However, the civil infrastructure community has minimally implemented AR technologies to date. One of the challenges that civil engineers face when understanding and using AR is the lack of a classification of AR in the context of capabilities for civil infrastructure applications. Practitioners in civil infrastructure, like most engineering fields, prioritize understanding the level of maturity of a new technology before considering its adoption and field implementation. This paper compares the capabilities of sixteen AR Head-Mounted Devices (HMDs) available in the market since 2017, ranking them in terms of performance for civil infrastructure implementations. Finally, the authors recommend a development framework for practical AR interfaces with civil infrastructure and operations.

Situational awareness is the perception and understanding of the surrounding environment. Maintaining situational awareness is vital for performance and error prevention in safety critical domains. Prior work has examined applying augmented reality (AR) to the context of improving situational awareness, but has mainly focused on the applicability of using AR rather than on information design. Hence, there is a need to investigate how to design the presentation of information, especially in AR headsets, to increase users situational awareness. We conducted a Systematic Literature Review to research how information is currently presented in AR, especially in systems that are being utilized for situational awareness. Comparing current presentations of information to existing design recommendations aided in identifying future areas of design. In addition, this survey further discusses opportunities and challenges in applying AR to increasing users situational awareness.
