This version of the app is written by Lam Yeung Shun under the supervision of Dr. Shiu Yin Yuen.

The application will act as a guide dog, as an auxiliary tool to guide the visually impaired people (VIP) to the destination in both indoor and outdoor environments. Under the guidance of the navigation, the VIP can easily follow the instructions from the recorded path. The path can be recorded by themselves or received from other users.
