Kinetica 絵文字＆キーボード アプリ 向け Android 説明
Kinetica is a two-handed keyboard. Both thumbs swipe or tap at the same time, independently, and the two gesture streams merge into one word.
Typing something: the left thumb taps S, then E, while the right thumb swipes O -> M and then T -> H -> I -> N -> G. The streams are merged by timestamp into S + OM + E + THING.
It is a spiritual successor to the discontinued Nintype, written from scratch on Android's public IME APIs - not a fork, and with no third-party gesture or prediction library. The dynamic time warping, the trie search, the path resampling and the dual-stream merge are all in the app, so every constant is understood and tunable.
The manifest declares no INTERNET permission. Nothing you type can leave the device, because there is no code path that could send it. Decoding, prediction and learning are local, the personal dictionary is on-device storage only, and password or private fields switch off suggestions, trails and learning.
Features
- Two independent swipe/tap streams merged by timestamp, including near-simultaneous order swaps and mid-swipe cross-thumb taps for double letters
- Swipe decoding written from scratch: banded dynamic time warping over arc-length-resampled paths, an anchored trie search, frequency and bigram-context scoring
- English, Italian, Spanish, Polish and Czech: 46k to 49k words and 40k to 100k bigrams per language, with real corpus frequencies. Accented words are matched through their base-key path and restored on commit (mesto -> město)
- Tap autocorrect with three aggressiveness levels
- Live completions while you tap, and the letters you actually typed are always a pickable suggestion, so a word the dictionary does not know still commits verbatim
- Personal weighting, kept per language: words you commit rank higher over time, long-press a suggestion to reinforce it, slide up or down while holding to change by how much
- Long-press alternates on every key, customizable edge swipes, chord shortcuts, a two-page symbols layer and a numpad
- Five layout modes (full, right, left, split, one-handed), adjustable height, a dark theme, Material You wallpaper colors, or a whole palette derived from one custom color
- Peck-type mode that switches decoding off entirely, for slang and anything else the engine would otherwise mangle
- Reversible backspace slide: the span to be deleted is previewed struck-through, sliding back retracts it, and only lifting commits it
- Dictionary management on the device: import an AOSP wordlist.combined, export or import your personal dictionary as JSON, reset it per language
