Palm OS Interface

Palm OSインターフェース / 1996–2009 / Style / Platform Screen Languages

Palm OS turned a tiny monochrome screen, stylus and strict memory limits into a consistent pocket work tool through the Title, Category menu, Command Bar, hardware buttons and Graffiti writing area.

A roughly 160 by 160 low-resolution monochrome screen / Title at upper left and Category pop-up at upper right / A Command Bar rising from the lower edge and four application buttons / Thin one-bit icons, rules and the Graffiti input area

Dictionary entry

Best used for
Handling calendar, contacts and notes quickly with an extremely small display and few inputs · Reconstructing an early PDA from its stylus-centered sequence, not only its pixel surface
Type
Use a sturdy bitmap face that separates letters at small sizes and reduce labels to one word.
Composition
Fix Title and Category above, the list in the middle, and commands and input below to reduce screen changes.
Material
Work in one-bit black and white, using thin rules, reversed selection and roughly 16-pixel icons for state.
Caution
Monochrome pixel UI alone is not Palm OS. Preserve the division of work among stylus, hardware keys, Graffiti and on-screen commands.
