Qualche tempo fa mi era capitato di riflettere sull'evoluzione della combinazione palmare/cellulare . La mia idea in proposito è che la tastiera come dispositivo di input esterno allo schermo scomparirà in qualsiasi oggetto di questo genere e sarà simulata a video. L'idea dell' Ultra-Mobile PC (è questo il nome ufficiale del dispositivo chiamato Origami) va in questa direzione. Quando it comes with a keyboard on the screen must not have imagined a mere simulation of the keyboard tradizioale. Experts on the history of technology often citing the case of evolution from the keyboard of the typewriter to the computer. The layout of the letters, which in the typewriter was constrained by the mechanical object, remained unchanged in spite of the fact that alternative layout showed a higher efficiency. Computer keyboards do not exist in the mechanical restrictions that led to the QWERTY layout and yet we have maintained the same standard precendete. Similarly it seems that there has been moved, at least at an early stage, for the simulated keyboard on the screen. Having the entire set of buttons in a certain way (see the handhelds, tablet PCs or machines to make the tickets from the station) is certainly not the most efficient way to simulate a keyboard (ie SIP, soft input panel). With the UMPC I have seen the first alternative in this regard.
The layout of the buttons in the bottom corners is certainly unusual but I think, having experience with a PDA like the JASJAR EMI, which will be very useful especially in terms of mobility. However, I think that we will use the video button in the next few years will still be different. What need is there to show all buttons on the screen when ineffective, based on the chosen language, we know that only some letters may follow those actually be written? Big buttons (easy to press with your fingers) and saving screen space by showing only the relevant letters. A key role is then played dall'autocompletamento T9 style. So the device of the future will be no keyboard
