Svetlana's ideal tactile surface...
- Closely spaced bumps are most effective. They create a greater frequency when run over with a cane, making them more noticeable.
- Patterns that are effective at all angles. Some patterns can be hard to recognize because a cane may be rubbing in the same direction that the bumps go rather than across the bumps.
- Use a material that reacts well with seeing canes. Some softer surfaces can seem to be stickier than harder surfaces, making it hard for canes to run across.
- If bumps are placed under raised appliances, they should extended slightly further than the actual object. This alerts the blind where an object is before they get to it.
- Bumps should not extend into bathroom pathways. Poor placement of a tactile surface can prevent others such as wheel chair users from accessing the restroom.
