• Echolocation as an Accessible Navigation Tool in a Virtual 3D Environment

  Mai Ricaplaza Thøgersen, Rasmus Jens Frølich Kjeldsen · 2024 · Assets '24: Proceedings of the 26th International ACM SIGACCESS Conference on Computers and Accessibility

  This paper investigates whether active echolocation — emitting a sound and interpreting its echo — can serve as a viable navigation tool for blind and low-vision (BLV) individuals in virtual 3D environments. Virtual spaces remain overwhelmingly visual, lacking the physical and…

• Uncovering Visually Impaired Gamers' Preferences for Spatial Awareness Tools Within Video Games

  Vishnu Nair, Shao-en Ma, Ricardo E. Gonzalez Penuela, Yicheng He, Karen Lin, Mason Hayes, Hannah Huddleston, Matthew Donnelly, Brian A. Smith · 2022 · Proceedings of the 24th International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS '22)

  This paper investigates how visually impaired players (VIPs) gain spatial awareness within 3D video games by comparing four leading spatial awareness tool (SAT) approaches. The researchers built Dungeon Escape, a 3D third-person adventure game using Unity, featuring four dungeon…

• A Participatory Design Approach to Creating Echolocation-Enabled Virtual Environments

  Ronny Andrade, Steven Baker, Jenny Waycott, Frank Vetere · 2022 · ACM Transactions on Accessible Computing

  This participatory design study investigates how echolocation can be implemented in virtual environments to make them accessible to people with visual impairment. The researchers worked with three expert echolocators—people who have developed the ability to use sound and its…

• Echolocation as a Means for People with Visual Impairment (PVI) to Acquire Spatial Knowledge of Virtual Space

  Ronny Andrade, Jenny Waycott, Steven Baker, Frank Vetere · 2021 · ACM Transactions on Accessible Computing

  This study investigates whether echolocation—the use of sound reflections to perceive spatial information—can enable people with visual impairment (PVI) to acquire spatial knowledge of virtual environments. The researchers built a virtual world using Unity 3D and the SteamAudio…
