The concept of a keyboard that is really a touchscreen with haptic feedback on which you can type is not new to smartphone and tablet users who use this method, but on PC that is not common. However, there is the possibility of keyboards that are themselves a screen. Why has this concept not been standardized on PC?
The feeling of typing is important
One of the things that are key in the daily experience with things is touch, we do not give importance to it because they are there. The simple act of typing supposes a sensory feedback due to the return of the key, to which we do not pay attention until we change our conventional keyboard for one that does not give the same response.
When the first iPhone appeared, one of the technologies it brought with it was capacitive touch screens that allowed you to interact with them without the need for a stylus. So it soon became clear that you could type on these screens, but for those of us used to haptic or tactile feedback the lack of response seemed unnatural to us. So the development in the following years was the creation of systems that gave a sensory response to users when touching said screens and eventually develop keyboards with new technology.
In recent years there has been a lot of research on the switch creation who are in charge of giving feedback on the use of a touch screen as if it were a keyboard. The problem is that most of these solutions are being used in touch panels for the presentation of information in ATMs or direct sales systems.
There are keyboards with haptic feedback
Although these are not usually very popular in use due to their high price and as we have said before they do not yet provide the tactile sensation of a conventional keyboard, this solution should not be confused with that of keyboards such as the Optimus, which is based on the concept that each key has a display built into itself but using conventional mechanical switches.
What we are talking about is the construction of a keyboard that is based on a single display with haptic feedback hardware for each key that emulates the different switches. The problem? These would be extremely expensive to implement compared to a conventional mechanical switch. It must be taken into account that users are not used to paying large amounts of money for a keyboard and such a solution raises the price of a keyboard with haptic feedback several times over and this is not good enough to result in the replacement of the keyboard of a lifetime.
In other words, and to conclude, it is the same case as the urban legend of the pencil and the development of the space pen, and it is that most of the time the simplest is also the most functional.
