Benutzereingaben prufen
Es gibt nur wenige Anwendungen, mit denen Benutzer nicht über Eingaben mit deren Schnittstelle interagieren können. Nutzer müssen auf die eine oder andere Weise Daten in Ihrer Anwendung eingeben können und verwenden dazu beispielsweise Text, Felder zur Datums- oder Uhrzeitauswahl, Optionsschaltflächen oder Kontrollkästchen. Eingabeme-chanismen stellen zwar Eingabemöglichkeiten für Benutzer bereit, können aber leider nicht mit ihnen plaudern oder spontane verbale Hinweise geben. Die Verallgemeinerung der Eingabe erstreckt sich auch auf Schaltflächen, das Streichen uber den Bildschirm, das Drücken oder Antippen von Optionen, Menüs und verschiedene andere Optionen. In diesem Kapitel beschränke ich mich auf freie Texteingaben, Datums-/Uhrzeitauswahl und Alarmmeldungen.
