Unanticipated design issues with the tactile map after deployment and ways to address these issues.

Design aspect	Deployed tactile map	Design improvement in deployed map or future iteration
Map legend	Braille	Students reported difficulty reading the legend. We were unaware of Braille standards when the map was printed. A new design would incorporate the standard.13,14 Also, not all students use Braille; a combination of Braille and raised text is ideal
Protective case surrounding map	Protect map from the elements	Heat/humidity build up inside case caused the electronics to stop working temporarily. Removing the protective case would stop the heat and humidity build up
Roof over map	To protect the electronics and map from the elements	Roof was too low, such that when taller children were reading the map, they would bend their heads in the process and lean in to the map, and there was no clearance between the child’s head and the beam support of the roof. Raise the height of the roof
Electronics	To provide auditory descriptions of parts of the playground	Eliminate the electronics (teachers and students reported not using them often, and that children would feel the entire area within the case, and would touch the speakers at the back top of the case, which we didn’t intend) or make them better quality (not as much maintenance on the part of LSVI staff, components not included in tactile area; a more robust auditory design is underway)
Orientation for use	Placed tactile map in same orientation as the playground	Having a “you are here” marker would aid in orientation
