Mapping applications on mobile devices have gained widespread popularity as a means for enhancing user mobility and ability to explore new locations and venues. Visually impaired users currently rely on computer text-to-speech or human-spoken descriptions of maps and indoor spaces. Unfortunately, speech-based descriptions are limited in their ability to succinctly convey complex layouts or spacial positioning.

Timbremap is a sonification interface that enables visually impaired users to explore complex indoor layouts using off-the-shelf touch-screen mobile devices. This is achieved using audio feedback to guide the user’s finger on the device’s touch interface to convey geometry.
