Text input is corrected on a touch-sensitive display by presenting a list of candidate words in the interface which can be selected by touch input. The candidate list can include candidate words having two or more character types (e.g., Roman, kana, kanji). In one aspect, the candidate list can be scrolled using a finger gesture. When a user's finger traverses a candidate word and the touch is released, the candidate word is inserted into a document being edited. In another aspect, characters can be erased by touching a key (e.g., a backspace or delete key) and making a sliding, swiping, or other finger gesture. A number of characters proportional to a distance (e.g., a linear distance) of the finger gesture across the display are erased. If there are characters in a text input area, those characters are erased first, followed by characters in the document being edited.

There is disclosed an internal sizing apparatus comprising a pneumatically activated probe that moves axially within a shoe and non-destructively measures the interior dimensions of the shoe. A linear pneumatic actuator is mounted between a heel piece and a probe. A linear potentiometer is mounted above the actuator and also connects to the probe. The apparatus is inserted into a shoe with the heel piece seated against the interior heel portion of the shoe.

The potentiometer then measures the linear distance traveled by the probe and thus determines the internal linear dimension of the shoe. Depending on the type of probe, three-dimensional internal measurements of the shoe can also be quantified.

In an LCD apparatus having a backlight assembly, a light guide plate includes an incident surface for receiving light, a reflecting surface for reflecting the light and an emitting surface for emitting the light. A linear distance between the reflecting and emitting surfaces is smaller than a height of the incident surface. An optical sheet is positioned at the emitting surface having a height lower than the height of the incident surface.
