Back to the Future - Morse Code and Cellular Phones
Back to the Future - Morse Code and Cellular Phones: "I've spent most of the past five or so years thinking about handheld devices, their limitations and how to work around them. Having worked with telephones since I was in high school, this has been something of an obsession.
The hot trend today is to cram every feature imaginable into mobile telephone handsets. This has led to some cool things like camera phones, mobile gaming, and such. The problem is that a lot of designers overlook some basic limitations in these devices, and more importantly, the situations in which people use them.
Cellular phones are all about mobility. Good mobility applications recognize that the user is often in motion (walking, driving, etc). Safety and convenience require that the application should demand as little visual attention as possible. Badly designed applications force the user to stare at the telephone's display instead of paying attention to surrounding environs. This is why speech user interfaces work so well for mobile users. They allow the user to interact with a service in a 'heads up' stance, without looking at the phone. Unfortunately, most mobile applications are of the badly designed 'let's take a PC interface and shrink it down' category.
Text messaging is an enormously popular service, but it too suffers from this basic user interface conflict. Sending and receiving text messages requires the user to look at the display. Receiving messages can be done at a glance, so this is not such a burden. Sending them is another story. Some people are adept at tapping messages on numeric keypads, but doing so requires the user to pay attention to the display. Try writing a text message without looking at the phone. Not easy.
'Tapping'
Morse Code, or a derivative of it, could be one way to solve this problem. With Morse Code, one could tap text messages out without looking at the telephone, and without having to fumble with ever smaller keypads. I'll admit that the idea of resurrectin"
