Google Glasses:
Vannevar Bush talks about a camera that a person can wear to capture instant photographs of their surroundings. In the article, he talks about this camera as a small device. An example of this is the Google Glasses Launch in 2014; although it is no longer commercially available, it was a product that introduced real-time VR and AR capabilities, and one of its main features of a camera. Users can walk around and take instant photographs of what they see from their glasses. This is quite similar to the wearable camera Vannevar explained in his article.
Data Dashboards
Another technology Vannevar Bush talks about is combining different sources of data into a single document that many people can view. This idea is quite similar to the data dashboards presented today to visualise data from various places, sources of people. Visually illustrating this complex data that anyone can understand.
Printable cameras
Vannevar also talks about a device that can print photographs instantly. This concept is very similar to the Fujifilm Instax camera and the Polaroid camera range, instantly printing images right after you take a photograph.
Speechify
In the article, Vannevar also talks about technology that turns text into speech and vice versa. This concept is similar to Speechify, a digital product that reads out any highlighted text to you. Recently Speechify has been used in schools to help support children and young adults with learning disabilities such as Dyslexia. This product also transcribes your words into written text, which is very similar to the theoretical concepts described in the article.
Digital Books
Lastly, Vannevar talks about a product that brings out specific books you are looking for from a digital library. This is very similar to the Kindle, online digital libraries, and even audible. Gathering specific books from a vast database and presenting them through different media, whether that would be as a digital book or an audiobook.
