WordWise. Shift-WordWise required use of a modified CHELNSTY keypad with those letters being selected by a shift key that could be allocated to the 1 button. From his lawsuit Kosover alleges he has some input into the development of the WordWise system during his time at Eatoni to August 1999. It was designed to complement LetterWise and targeted for keyboards on mobile devices. Eatoni's website indicates that it is possible for standard WordWise to add additional words to the dictionary on the device however this capability is no mentioned in Iridium satellite phone manuals so the capability might not be present on all versions of WordWise. If WordWise is unable to suggest the required word either through it not being in the dictionary or due to a keying error the required word will need to be entered in another mode such as LetterWise which can be switched to relatively easily. It has been suggested that WordWise is less sensitive to keystroke errors than competing T9 text prediction technology. A multilingual WordWise implementation is included in Iridium satellite phones. Eatoni's website also indicated it was included as their SMS, Twitter and e-mail downloadable client applications for certain Symbian and Apple IOS based products. Adoption Despite intensive marketing attempts in the early 2000s LetterWise and WordWise were not widely adopted by cell phone manufacturers with the Multi-tap and T9 system holding the market. LetterWise did find some adoption for DECT cordless phones, which were typically constrained by more limited resources, with Eatoni claiming over 20 million devices capable of LetterWise being shipped. From 2009 certain Iridium satellite phone models were shipped with both LetterWise and WordWise though not necessarily enabled by default; as of May 2019 some of these models seem current.
