Saisie de données pour interfaces réduites avec Glyph: principes, niveaux de saisie et évaluations théoriques

ABSTRACT

Glyph is a new data entry method designed for different interaction styles. Glyph is based on a reduced set of six shape primitives, plus a seventh «segmentation primitive ». The data input is made by seizing sequences of primitives with a maximum length of three.The segmentation primitive allows to handle three input modes: character input, text edition and system command. The character input is based on a decomposition in basic shapes according to a principle of analogy with Roman characters.This paper presents the different input levels, the character charts, and results of a theoretical evaluation on the character input. Two types of interface are considered. The first one is a dynamic soft keyboard specifically designed for stylus-based entry and the second one is a reduced physical keyboard design for devices as phone portables.
