It's a simple approach once the process is understood. Basically, the partners provide the scanning by pointing and/or speaking the names of items/pictures visually and/or auditorily.
- When it is visual, the individual relies on visual recognition of the symbols. The partner scans by pointing to items with a finger or light without using any verbalizing.
- When it is auditory, the partner reads the labels for each symbol or a group of symbols. The individual listens for their desired label.
- Visual and auditory is when the partner both points to and reads the labels for each symbol. The individual may rely on their understanding of the spoken labels and/or visually recognize the symbols being used.
