Keypads are described which are row similar to a standard telephone keypad though they have a different number of columns of base-letter-assigned keys than the standard to which they are related. Smooth sequences of such row-similar keypads are exhibited. Keypads which support both row-similar telephone keypad layouts and reduced layouts corresponding to typewriter standards are disclosed. It is shown how to combine various structural and statistical limitations with row similarity. It is also shown how to embed a row-similar digit layout in row-similar base letter layouts, and how to beneficially provide negative space between keys, construct pseudo standards, and extend or reduce desktop standards or pseudo standards while obeying structural or typability constraints.

An ambiguous keyboard has three to five columns and at least three rows of keycaps, each with three actuators arranged in a triangle. At least nine keycaps have a digit entry portion at either the keycap's top or bottom portion, a number digit, an actuator and a sensor. At least nine keycaps have left and right non-digit symbol entry portions. A plurality of the keycaps have at least one non-digit symbol assigned to them. Pressing the right non-digit symbol entry portion activates the sensor for the right non- digit symbol entry portion and pressing on the left non-digit symbol entry portion activates the sensor for the left non-digit symbol entry portion.
摘要:
An ambiguous keyboard which is sufficiently typable and similar to conventional keyboards to both expert and novice users. The layout of the key involves reduction in the number of keys (5101-4523) and placing several letters on each of the key (5101-4523) to accommodate reduction in size of the keyboard without overly compromising text-entry capacity.

Languages based in whole or in part on ideographic characters such as Chinese, Japanese, and Korean, are often are entered in a computerized text-entry system in a two-phase process. In the first phase, symbols from a first pre-conversion set are entered (200), then in the second phase, these pre-conversion symbols are converted into a second set of post-conversion symbols (202). The method and apparatus is to automatic convert of pre-conversion symbols into post-conversion symbols without requiring an explicit conversion signal to be input by the user. It accomplishes this goal though the design of trigger sequences of keystrokes which are substantially functionally equivalent to an explicit conversion signal input by the user (210). An apparatus constructed according to the trigger sequence method is particularly well adapted for use on reduced keyboards, and in conjunction with predictive text-entry methods.

This invention teaches that a single auxiliary key 1006 can support a multiplicity of ordered groups 1003-1004 and that only a subset of each group 1003-1004 needs to be visually represented on the face of a key, and that either multi-tap or predictive methods, or both, can be used to input members of each groups, and that auxiliary keys 1005-1007 are a convenient and effective method to select ordered groups, and to perform the multi-tap function. This invention teaches: limited multi-tap depth, reduced keystrokes per symbol, discoverability, graduated discoverability, compact presentation, and seamless integration of multi-tap and predictive methods.
