Abstract

In some embodiments, input devices and related systems and methods for electronically inputting characters of a pictographic language are disclosed. In one embodiment, an input device for a pictographic language includes a touchscreen display, and a display controller programmed to display a first arrangement including a first set of characters of a pictographic language on the touchscreen display. The first arrangement includes a plurality of regions, each of which contains a plurality of characters of the first set of characters of the pictographic language. The touchscreen display may be programmed to receive selection of one of the regions, and to receive selection of one of the characters in the selected region after receiving the selection of the region. Advantageously, the input device can be effectively used by both non-speakers and language learners as well as native speakers.
