These tools encourage or facilitate communication and assist in the input or output of information to computers.
Communication can be oral, written, gestural or mimic, which can be supported by a wide range of technical and digital aids. With the help of the Internet and its access through computers, mobile phones and many other products, people can inform themselves more easily or communicate better with each other. But non-technical products are also important for communication. The focus here is on the convenience and application possibilities for the users.
