Which tool is commonly utilized during OandM training to assist navigation?

The correct choice highlights the importance of electronic travel aids in orientation and mobility (O&M) training. These tools are specifically designed to support individuals with visual impairments in navigating their environments more effectively. Electronic travel aids can include a range of devices such as GPS systems, smartphones with navigation apps, or other technologies that provide audio or tactile feedback to help users identify their surroundings and plan routes.

These aids enhance spatial awareness and promote greater independence by offering real-time information and assistance. This is crucial during O&M training, as learners need to develop their navigational skills in various settings. While drones, smart glasses, and manuals on geography may have potential applications in other contexts, they do not serve the specific direct assistance role in navigation that electronic travel aids provide. Drones may be used for aerial mapping or monitoring, smart glasses might offer augmented reality experiences, and geography manuals can provide contextual knowledge, but none of these options directly facilitate the practical navigation assistance necessary for O&M training as effectively as electronic travel aids do.
