Found Images for my Idea

During our previous class we were told to surf the internet and search for images or media that closely resemble our ideas in order to explain it. During the previous weekend I came up with the following images.

 

My idea was to create a navigational mobile app that would allow blind people to navigate in shopping complexes with haptic vibrations from the watch. Upon relaying my idea to Eleni, I found out from her that the idea would lead to certain complications like getting ethics permission to test my idea with the visually impaired community. This made me to question my research question again.
