  • the full data entry capacity of the all the fingers is utilized.
  • Text entry means should also be universal in nature, in that they may be used and readily adapted so as to be able to enter the characters that are associated with various languages. With the growing number of users who make use of devices to enter text for various purposes, it should be borne in mind, that English may not be the language that is used by all people with respect to their choice of a language in which to communicate. Increasingly, throughout the world, many people are bilingual or even trilingual. Therefore, a text entry means should have its keys or mechanisms by which characters are entered oriented such that they may be used with ease for the entry of characters associated with multiple languages.
  • Text entry means should also more importantly provide an efficient means by which text may be input, so as to combine a high speed of input with a low error rate associated with the text entry.
  • text entry means In order for text entry means to be more efficient, they generally should place less reliance on visual monitoring, meaning that the required actions for entering characters must be such that the user may commit such actions to memory and place less reliance on visually monitoring the actual inputting of a character.

  • the text entry mechanisms that are associated with SMS services are in general inefficient, as due to the size of devices associated with SMS services, the keys that are associated with such devices do not allow for ease of manipulation. Further, the user is frequently required to strike a key associated with the device more than two times to produce a desired character. As a result, the speed by which text may be input is hindered due to the inherent limitations that are associated with the text entry functionality that is provided with SMS capable devices.
  • Embodiments of the invention are generally directed to a method and system for text entry, wherein no reliance is placed on visually monitoring the method of text being entered, and wherein the method and system allow for universal application so as to be able to allow for the input of characters that are associated with various languages.

Each gesture type category includes various specific gestures. The activations associated with the gesture type, defines the total number of specific gestures possible from the gesture type. In the preferred embodiment, four different gesture types provide seventy-five unique outputs. The four gesture types are defined by the order and duration of input detector activation.

Time durations for activations are mentioned for purposes of illustration, and they may be altered to suit user demands.
  • the timing measurements may be replaced with pressure, speed or other tactile requirements depending on the gesture type implemented.
  • the first gesture type is a single long activation of any input detector held for at least a predefined duration. Tapping a single input detector for less than a predefined duration results in a null output.

  • mapping of the characters to the gestures takes advantage of structural symmetry present between either or both, of the phonemic system of the language and the script system, with that of the system of gestures used in this invention.
  • Prior art keyboard design has long recognized that relating the mapping of keys to the phonemic system of the language is advantageous. Dvorak placed the five vowels of the English language under one hand.

This becomes evident when one considers that an embodiment of the method exists through placing activators of some kind on the fingertips themselves. These activators can be used on any surface and without any targeting requirement. Reliable and accurate text output could be achieved even while the user simultaneously sweeps their hand from side to side across the contact surface of a table, wall or their own body.
  • gestures are mapped to the phonemic dimensions of the language.
  • Some languages such as Tamil and English are termed "diglossic" because the script and pronunciation do not reflect each other.
  • some of the gestures would not relate to phonemics but instead, the gestures would relate to other aspects of the spoken language such as the frequency of use for a character in a particular language. Both the frequency aspect of the written language and the phonemic aspect are then used for these languages. This concept may be extended to any language.
  • Figure 5B depicts a diagram mapping phonemic relations of Hindi characters to specific gestures used to output the specific Hindi characters. It is assumed that the reader holds a sufficient knowledge and understanding of the Hindi language to understand the following example.
  • the use of specific finger names is in relation to the use of a five input detector text input device 100 with the right hand.
  • Voiceless sounds are symmetrically placed on the gestures proceeding towards the thumb 110', or in other words, the cells in the lower right portion of the diagram from the shaded diagonal.
  • Voiced sounds are placed on the gestures proceeding towards the little finger 150', or in other words, the cells in the upper left portion of the diagram from the shaded diagonal.
  • the voiceless stop sounds lie horizontally along the lower row.
  • the voiced stop sounds lie vertically along the far left column. Voiceless consonants are thus mapped to the second gesture type using a short- short activation sequence.
  • the corresponding aspirated sounds follow the same logic.
  • the third gesture requires that the second, long activation be held beyond a predetermined period. This held gesture corresponds to the aspirated sounds within this group of sounds.
  • the voiceless labial sounds are placed on the thumb but the voiced labial sounds would theoretically be placed on the little finger 15O 1 if a perfectly ordered relationship is desired. However, other factors need to be addressed when deciding on the mapping of characters to gestures.
  • the little finger 150' does not have an independent neurological manipulation. It shares neuronal pathways with the ring finger 140'. Thus, it is more difficult to control the little finger 150'.
  • the voiced labial sounds are therefore shifted to the more agile and stronger ring finger 140'.
  • the five nasal consonants are used quite frequently and are mapped to the gestures that are easily performed.
  • Characters representing "ma” and "na”, the two most used nasal consonants, are associated with the second gesture with alternating sequences of the index finger 120' and middle finger 130'.
  • Another frequent nasal consonant, Nukta is placed on the third gesture using the middle finger 130' to index finger 120' sequence.
  • the Anuswara is placed as the third gesture type using the middle finger 130' to index finger 120' sequence.
  • the vowels are mapped to the single long first gesture type and to the second gesture and third gesture types that use a repetition of a single finger.
  • the three vowels "A”, “I”, “U” are input using the third gesture type of each of the three inner fingers of the hand - index 120', middle 130' and ring 140' fingers.
  • the short and long vowels for "I” and "U” are created by two identical consecutive gestures. The first input generates a short vowel and the subsequent immediate repetition of the gesture transforms the previous short vowel input into a long vowel. This requires an additional keystroke. However, the frequency of the long vowels are minimal compared to the short vowels. It is more efficient to map the long vowels to additional keystrokes involving repeating the same gestures of the same fingers, than to assign a low frequency character permanently to one of the gestures available. That would eliminate the individually mapped gesture from common use.
  • Halant character representing a joining action of two distinct characters into one combined character. It is frequently used and thus, is mapped to an easily performed second gesture, the ring finger 140' followed by the index finger 120'.
  • a specific example of special scripting rules in Hindi is when the initial character of a word is "ra”. If followed by “u” or “uu” it takes two different specific glyphs that are conjuncts of the "reph” and "u” glyph. These two symbols are automatically selected based on processing logic.
  • the vowel "R” has two matras depending on the shape of the preceding consonant.
  • the oblique stroke or the inverted “v” matra is automatically placed as necessary by processing logic.
  • the use of only one specific gesture by the user will allow the input of both of these characters in their correct context based on the processing logic. As such, the user does not have to select an entirely new character for the associated sound.
