Ergonomic Keypad

When you hold the phone in your hand, you will notice that, not all the keys of the phone are equally comfortable for your thumb. Say, if you are holding it in your right hand, the key 1 is the easiest to reach and the Key # is the hardest. However, no consideration has ever been paid to that ergonomic aspect for the allocation of the characters on the keypad.

In the dynamic keypad of Panini Keypad, we had the opportunity to assign characters dynamically to the keys and hence we place them according to their Ergonomic ranks. The most probable characters on the top left corner and then going down to the bottom right corner.

The user is allowed to swap to Left handed assignments in the middle of a word if he wishes.

This particular innovation is also new and was the cover story of the journal of the Ergonomist Society, UK in its March 2009 issue within two months of the release of the product.

We also offer other variations like an Ergonomic Persistent and Nearest Key assignments as options for the user.

In the Ergonomic Persistent

Characters that were once assigned retain their positions over the next allocation if they are common. This is useful for languages like English where characters repeat, for example the occurrence of "tt" in word like attached. The user expects to find the next t in the very same place where the previous 't' occurred. For him the Ergo-persistent is useful.

In the Nearest Key Mode which is meant for the touch screen devices, characters are assigned at the very same place where the screen was touched last or crowded close to it so that the finger would need very little movement to type.

There is also a Legacy Mode that was developed for some phones where characters are preferentially placed in the same places where they belonged in the legacy ITU keypad. People who are habituated to that fixed keypad would find the characters in the same position but they would not have to Multitap.

This is only applicable for Latin script languages for which there is a legacy.
