What is the preferred type of symbol selection for someone who is visually impaired?

The preferred type of symbol selection for someone who is visually impaired is textures. This choice is correct because textured symbols provide tactile information that allows individuals with visual impairments to distinguish between different symbols through touch. Textures can convey meaning effectively without relying on sight, enabling users to recognize and differentiate between symbols that represent various concepts or items.

In contrast, miniatures, written words, and abstract symbols primarily rely on visual recognition, which may not be accessible to someone who cannot see well. Miniatures might be too small or detailed to feel differences readily, written words would require some level of visual acuity to interpret accurately, and abstract symbols may not have a clear tactile representation, making them less suitable for individuals who are visually impaired. The emphasis on tactile feedback in textures effectively addresses the communication needs of this population.
