![]() ![]() This IC receives a signal when a switch is innervated. However, turning the page and pressing a new z-axis, say page 2, and then the same x,y-axis content position as page 1, gains the following coordinate structure: 2,1,1.Īn integrated circuit (IC) is located either within the printed material or within an enclosure that cradles the printed material. For example, 1,1,1 indicates a z-axis of 1 (page 1) and the x,y-axis is 1,1. ![]() When the unique z-axis is interacted with, x,y-axis can have identical touch points as other pages. Z-axis can be offset around the boundary of the page. Turning pages and interacting with new pages that may have the same touch points as previous or subsequent pages, a z-axis may be used to indicate the plane of activity. TUI icons may be used to indicate to the reader of the printed page what action will occur upon interacting with a particular position on the printed page. The database retains the correct pathway to retrieve the associated digital content or launch the appropriate application. The switching sensor cross-references with a database. By interacting with the switch through touch or presence, an action is innervated. Not to be confused with electronic paper endeavors, the TUI requires the printed pages to act as a template or overlay to a switch array. Generally, the TUI requires pressure or presence with a switch located outside of the printed paper. Whereas a graphical user interface (GUI) relies upon the sense of sight, a TUI enables not only the sense of touch to innervate and activate computer-based functions, it also allows the user, particularly those with visual impairments, an added level of interaction based upon tactile or Braille input. (I won't go into great detail about all the things GPG Suite can do, but here's a bunch of documentation about the software if you're interested in learning more.For other uses of the term "touch user interface" when applied to touchscreens, see Multi-touch.Ī touch user interface ( TUI) is a computer-pointing technology based upon the sense of touch ( haptics). It is a program that makes it easy for people to encrypt and decrypt messages. I generated my own encryption key using software called GPG Suite. Given that no one but you knows the private key, it is nearly impossible for anyone to intercept the message and decode it. You must then put your private key into the PGP software to decrypt the message. So I send you a message that is encrypted using your public key. Then, using software, I write my message and the text is ciphered in a way that is unique only to your public key.īut the only way for this message to be deciphered is to use the second part of the puzzle - your private key. PGP works like this: If I want to send a message to you, I first need to know your public key (there are online repositories with public keys available). Everyone using PGP must have two keys - a public key and a private key. A PGP key is a way that internet users can encrypt their messages, making it nearly impossible for anyone but the sender and receiver to read the message. PGP stands for Pretty Good Privacy - no joke. Using these two pieces of information, I delved further, and ultimately found a way for us to talk in private. It boiled down to a possible email address that he used and a PGP key (see my explanation on what that is below). Using the information this Tox hacker had posted, I had very few details on how to contact him. He also posted a few updates on Pastebin, a website hackers frequently post messages, including the announcement that he wanted to leave behind his life of cybercrime. The hacker communicated using the dark web - forums on websites that could only be accessed using web browsers that anonymize traffic. I became aware of a teenage hacker who made a malware platform called Tox that was quite powerful. ![]()
