  1. On the topic of editorial decisions (and the next article): Seriously HaD? You are now going the way of the verge and engadget before it and destroy your website?
    I guess it could be MAGA style philosophy creeping into the thinking of all of society.
    But sure, dig on, it’s your choice.

  2. Hi, I wanted to understand better how it works, I mean, ToF are like a laser so it decets only an obstacle in a single point, so how to detect an obstacle in the area where a blind person is walking?
    Do you need to use a 3d camera with a pool of sensors, or a couple of servos to move up-down left-right the sensor

    1. Thanks for the question. The ToF sensors have are detect things in a cone of about 25 degrees. The up and down scanning part is done by the wearer. Just like sighted people look around to see what is around them.
