The values are small throughout, and this is because the figure is an average over all characters entered. Asked 6 years, 11 months ago. It used to be hard to get Swype unless you jumped through hoops or carefully selected the right phone model. Finding a Key The time to find a key, t F , was defined operationally as the time from the last keystroke of one character to the first correct keystroke of the next character. At wpm, the predicted entry rates for LetterWise rates are lower than those for T9 , however, they do not carry similar assumptions with respect to ambiguous words or non-dictionary words. To enter on the user presses 6 three times, waits for the system to timeout, and then presses 6 twice more to enter n.

It is possible to compute the KSPC characteristic for a given entry technique using a language corpus see [8] for details. Another approach is to press a special key to skip the timeout "timeout kill"thus allowing direct entry of the next character on the same key.
As another example, a collection of text from the Wall Street Journal containing 20, words was found to contain not only 8, ambiguous words, but also 4, words which were not in Webster's seventh dictionary [2].
In many cases t A was zero as no adjustment was necessary. This T9 implementation attempts to notify the user when a typing or spelling error occurs by beeping when the input does not match any prefix in the dictionary.
In practice, the memory requirements vary from about bytes to bytes. Press the key repeatedly until the letter appears. Adjust - if the desired letter does not appear, press the key again until it does.
LetterWise: Prefix-based Disambiguation for Mobile Text Input
Furthermore, the technique is not limited to the entry of words in a stored database, as with dictionary-based entry methods. As noted by Silfverberg et al.
Post a Comment Comment. We extracted the entry time for each word considering only the time to find each letter in mobilerextinput word, t F. To examine the performance cost of interaction in the presence of non-dictionary words, we undertook a parametric analysis based on our data.

Once the user successfully enters the first letter in a word, the need for presses of NEXT is greatly reduced see Figure 2. Subscribing to a newsletter indicates your consent to our Terms of Use and Privacy Policy.
In comparison with the Fitts' law predictions in Table 1 for Multitap index finger, timeout kill and LetterWiseour participants are well short of reaching their expected asymptotic rates. Only slight improvement appears thereafter. Since the acquisition Nuance has integrated its Dragon speech recognition technology into Swype, starting with recent beta versions and now in the version it is releasing to OEMs.
A sample of the code that is causing a problem is this: It is seen that t A for LetterWise bottom line decreases with practice, starting initially at about ms and dropping steadily to ms by session Although such behaviour is unlikely to ever take hold fully, the approximations afforded from Fitts' law analyses represent a useful point in the interaction space — an asymptote toward which experts progress.
Motor reflex acquisition phase. Netgear Nighthawk Next-Gen If it does not, press the NEXT key repeatedly until the right letter appears. Swype has done more to help improve input, at least on Android, than any other company.
To operate Multitap successfully, the user must discover the following processes for entering letters: For this reason, keystroke overhead occurs primarily at the beginning of words. It is well known that text messaging users employ a rich dialect of abbreviations, slang, etc. Normalizing mobiletdxtinput word frequency, One such technique is known as dictionary-based disambiguation.

We will describe the behaviour of LetterWise and T9 on non-dictionary words later. ExtremeTech has covered Swype and some of the alternative solutions before, but there have been some big changes since then.
The moniletextinput are small throughout, and this is because the figure is an average over all characters entered.
The improvement with practice is further illustrated in the trend lines and prediction equations in Figure 6.
