Spatial Scene Reading

A mode of scene reading interaction where users continuously drag their finger across a touchscreen to freely explore a virtual environment, with objects identified and announced as the finger passes over them. Spatial scene reading preserves the spatial relationship between touch position and object location, providing an intuitive mapping between the user's gesture and the virtual world. Spatial audio reinforces this mapping by conveying object positions relative to the user. Though used less frequently than sequential methods in studies, spatial scene reading supports autonomy and spatial awareness for BLV users exploring 3-D environments.
