Abstract

A mobility system for the visually impaired has a removable data processing module attached to a generally elongated collapsible pole. The pole has a proximity sensor located close to a pole first end and a second proximity sensor located a pole second end. The pole has a fingerprint scanner located close to the pole first end. The system has a data processing module that has a microprocessor, a power switch, a power supply, a charging port, a data port, a microphone, and a speaker located within the module housing. The microprocessor has a global positioning system component. The data processing module can be attached to the collapsible pole or carried by the user via a strap or a clip. The fingerprint scanner can turn on or off the system based on the fingerprint of the user.
