In terms of tactile clues, which do sensory features NOT include?

Sensory features primarily involve the use of touch-related information, which includes tactile and physical sensations that individuals can perceive through their skin. Tactile clues specifically encompass textural changes, temperature variations, and other sensations that can be physically felt.

Visual aids, on the other hand, fall under the category of visual stimuli, which are not tactile in nature. They do not provide information through the sense of touch but rather rely on sight. Thus, when discussing tactile clues, visual aids do not qualify as they do not engage the tactile sensory system, making them distinct from the other options listed.

Olfactory stimuli, though related to the sense of smell, are also irrelevant when specifically focusing on tactile clues. However, since the question seeks the feature that does not pertain to touch at all, visual aids are indeed the correct choice.
