ABSTRACT. Using touchscreens has largely limited user inputs to small form- factor devices. To address this constraint, we explore a novel. This paper describes a “relative keyboard,” where keystrokes are treated as inputs in a continuous space relative to each other, instead of a discrete. Forget Bluetooth, use paper!

The membrane layers can be printed by very-high volume, low-cost "reel-to-reel" printing machines, with each keyboard membrane cut and punched out afterwards. Plastic materials played a very important part in the development and progress of electronic keyboards. Until "monoblocks" came along, GE's "self-lubricating" Delrin was the only plastic material for keyboard switch plungers that could withstand the beating over tens of millions of cycles of lifetime use.

Greasing or oiling switch plungers was undesirable because it would attract dirt over time which would eventually affect the feel and even bind the key switches although keyboard manufacturers would sometimes sneak this into their keyboards, especially if they could not control the tolerances of the key plungers and housings well enough to have a smooth key depression feel or prevent binding.

But Delrin was only available in black and white, and was not suitable for keytops too soft , so keytops use ABS plastic. However, as plastic molding advanced in maintaining tight tolerances, and as key travel length reduced from 0. Control processor[ edit ] Scanning procedure Computer keyboards include control circuitry to convert key presses into key codes [47] usually scancodes that the computer's electronics can understand.

The key switches are connected via the printed circuit board in an electrical X-Y matrix where a voltage is provided sequentially to the Y lines and, when a key is depressed, detected sequentially by scanning the X lines.

The first computer keyboards were for mainframe computer data terminals and used discrete electronic parts.

The first keyboard microprocessor was introduced in by General Instruments, but keyboards have been using the single-chip microcontroller variant since it became available in This serial keyboard cable communication is only bi-directional to the extent that the computer's electronics controls the illumination of the caps lock, num lock and scroll lock lights.

One test for whether the computer has crashed is pressing the caps lock key. The keyboard sends the key code to the keyboard driver running in the main computer; if the main computer is operating, it commands the light to turn on. All the other indicator lights work in a similar way. The keyboard driver also tracks the Shift, alt and control state of the keyboard.

Some lower-quality keyboards have multiple or false key entries due to inadequate electrical designs. These are caused by inadequate keyswitch "debouncing" or inadequate keyswitch matrix layout that don't allow multiple keys to be depressed at the same time, both circumstances which are explained below: When pressing a keyboard key, the key contacts may "bounce" against each other for several milliseconds before they settle into firm contact.

When released, they bounce some more until they revert to the uncontacted state. If the computer were watching for each pulse, it would see many keystrokes for what the user thought was just one.

To resolve this problem, the processor in a keyboard or computer " debounces " the keystrokes, by aggregating them across time to produce one "confirmed" keystroke.

Some low-quality keyboards also suffer problems with rollover that is, when multiple keys pressed at the same time, or when keys are pressed so fast that multiple keys are down within the same milliseconds. Early "solid-state" keyswitch keyboards did not have this problem because the keyswitches are electrically isolated from each other, and early "direct-contact" keyswitch keyboards avoided this problem by having isolation diodes for every keyswitch.

You can enjoy the game for free. Games that started during the tutorial can also be played here, of course the contents of the game using paper keyboard.

Tap "Chat" if you want to use Paper Keyboard for character entry and mail exchanges. Tap "Unlock".

Tap "Buy". Purchasing requires yen charge. Tap "OK". Then tap "Ok" to complete unlocking, so that you can use all functions of Paper Keyboard.

Put the iPhone on paper while this screen is out I will set it like this. Tap the paper keyboard Characters are driven into the iPhone even though they are not touching. When you tap the paper keyboard, letters are struck on the screen of the iPhone, but the time lag is totally unlikely to say so at all, it is really amazing how high the accuracy is. However, when the finger is swaying within 15 mm above the printed keyboard, it may be recognized that the key is tapped, so it is necessary to take key point typing on that point.

Version 3. Now I know, most of might think that the concept to a paper keyboard is pretty good. To be honest, it is and that is why it got that one star. The reason why it didn't get the other 4 stars is because it is not user friendly, the paid features don't really work properly, calibration takes time and even after that the keyboard does not work properly and also, there's only one design for the keyboard.


By the way, the paid features are unlimited writing, google talk , facebook chat and there's one more messenger that I haven't heard of. Facebook chat says connecting but nothing shows up.

Google won't allow the app to use google chat because of weak security.

And the problem with unlimited writing is that when you type some letters, the letters above them is imputed. So, don't spend you money on this app.

Well, not right now. It really works fantastic.
