How to type
Just two rules
At the functional level there are only two rules for typing with Panini Keypad irrespective of the language and type of device. The rules are1. Look for the character on your screen, if you find it, indicate it, type it.
2. If you cant find the character, press the Next List Option till you find it.
The Next List Button is either indicated or it is the Big Select Button in the middle of your phone.
But apart from the two rules above let us explain a bit about how this works, so that you make better sense of what is happening.
Starting to write
At the beginning of your use, or when you put a space, there are always the same characters on the screen. These are characters that are statistically most likely to start a word in that language and you will find that this is quite true. If the character you want to start with is not on the list, press the Next List, once, twice or more to get the character you want. After you type that character, you will find that all the characters on the screen have changed to new characters that are most likely to be following what you have just written. If the character you want is not on the list, you can use the Next List button here too to find the character you want. The Next lists, several of them, are always arranged with characters with descending ranks in probability. As you enter more characters, the system goes on making more predictions which by now would have grown so tight that the next characters keep coming on the same key, generally the top left corner or around it. In this manner, you have to search very little and can write your difficult words with very little efforts. In most cases, the software is assisting you in composing the word correctly. This system works for every language and for every kind of device - normal phone or a touch screen one.
How to compose words correctly
The problem is not in the above. The problem is that most of us have grown unfamiliar with how words are to be composed correctly in Indian languages, easy words, and difficult words. These were supposed to have been taught in schools but were either not taught correctly or we have forgotten. For example, we dont know how to write a Yuktakshar, we dont know what are the consonants (Vyanjan varnas), the independent vowels (swar varnas), the matras (the dependent vowels), the symbols (like bindu etc) and how to use them and in which order to input into a digital device. This you have to learn. That matras follow a consonant sometimes before the next consonant. That a matra has to enter only after the consonant even though it may actually be written before it (in typography). The fact is that it is a dependent vowel, written only after the consonant. The Panini Keypad tries to assist by suggesting the characters correctly to you but you have to at least know something. The various types of characters are also shown in different colors to assist your understanding and searching. Remember that if you want to make a Yuktakshar of two consonants, you have to put the Halant (shown in red on the Panini Keypad) between the two characters. When you do that, the conjunct character will automatically be formed by the phones font rendering engine. Sometimes a yuktakshar can be of three consonants or more, same rules apply, halants between them. Here are a few examples for each languages provided below. You must try each of them by yourself on the Panini Keypad. Only when you do practically, will you learn, no short cuts will help here. When you get that right, you will be sprinting with the Panini Keypad. The space character which you put after finishing a word is always at the same place.
Space, Purn viram, Number, Symbols etc
After you have finished a sentence, press space twice and you will get a Purna Viram (Full Stop). You can explore the Up Down key of your Navigator buttons to find ways to enter numbers, symbols etc. You can even explore the Next Lists within them for more options. You can do everything with the Panini Keypad, all options have been provided for, please explore.
There is learnability
The initialized state of the characters, as when you are entering the first character of a word are always at the same places, so after using it for a while, you will know where they are and which list has the first character you want to enter. You will learn it and it will then come habitually. After the first character is entered; in most cases you are going to find what you want next in the predicted characters. And then on it will mostly lock on and characters will come to your fingertips. Occasionally you will have to go to Next Lists in the middle, especially for uncommon words or words outside the dictionary. It's just statistical. You will always get what is most statistically likely. That counts very well in the long run. This simple usability works equally well and effectively for all languages of India and also all others of the world and we have explored languages from every linguistic family. All languages are highly correlated and this has been exploited here.
All languages, All devices, One usability
The effort saved is huge in terms of number of key presses, the bother and the time taken. It also assists in your learning how to write a word correctly, pulling you from semi-literacy to full literacy in your language. The number of characters in an Indian language is around 60-75 depending on languages. The total number of lists is therefore about 6 or 7. In a non-intelligent solution your efforts would have averaged going through 3 or 4 lists to get what you want. The Panini Keypad brings that down to very little most of the time. In fact you will be most often by finding the character you want on the very same key which is really convenient. That's the whole point. Its also fun and game-like interaction as you play and write with the Panini Keypad and you fall in love with it. Its very simple and straightforward, teach it to others who need it more than you. The best part is after you have learnt it for one, you can always use that learning to write in every other kind of digital devices of the future. It can be used in all. All the best.
