Trying to shore up what many consider a significant weakness of most mobile Net devices — input — Compaq said Thursday that it will bundle predictive text input software with its new Pocket PC handhelds. The company said it would bundle the WordLogic Predictive Keyboard with the handhelds. It uses an on-screen, or “soft,” keyboard that predicts words as the user taps on keys. If the prediction is correct, the user taps on the word to enter it in a document or record. Like other handhelds, the iPAQs already ship with handwriting recognition and an on-screen keyboard for inputting text. However, some users complain that both methods are slow and frustrating. Predictive text is one way to speed up the input process.
