MultiTouchChecker(C#) – 水玉製作所

マルチタッチデバイスで何点取れているか、IDの振り方を確認するC#アプリ。
Flashでも似たものを以前作っていて、役に立ってはいるのだが、それはFlashでちゃんと動くことを確認するツールであった。しかし挙動が予想どおりで無い場合、それがFlashの問題なのか否かを切り分ける必要があるので、MS推奨C#でも同様のツールを作ってみた。
特にチェックツールとしての工夫は無いし、細かい動作仕様は異なっているのだが、C#、AS双方で確認するということ自体が意味があるはずだと考えて作った。

確認したタッチパネルはEIZOのT2351W（二点までの光学式）

Note: TouchDown イベントが発生する正確なタイミングは、指がタッチした際ではなく、タッチして移動を開始したときです。
