LiDAR is an emerging distance sensing technique with superior figure of merit compared to other electronic sensing methods such as sonar or Time of Flight (TOF). The dramatic reduction of the cost of LiDAR makes the case for ubiquitous applications where precision distance is required. With this in mind, we explore the adoption of LiDAR technology for the visually impaired. There have been a few publications on deploying LiDAR for the blind [1,2], however the prior solutions don’t address the needs for the deaf-blind, and these systems use a relatively expensive LiDAR in the Linux platform.
