This device is a dream come true for the visually impaired. I am sure that in future updated versions of this device, enhancements will come in the form of 'situational awareness' from a personal Lidar so that the wearer can move about more confidently without walking aids and minimize untoward incidents.

Pros:

1. Lightweight and 'regular' looking so that the wearer need not feel self-concious
2. Text to sound conversion is brilliant!
3. Facial recognition will lead to a significant improvement in the quality of life
4. Identification of currencies and shopping items will be huge conveniences

Cons:

1. Not priced for mass adoption yet
