First, go to the Dasher Online Demo. If your connection is slow, you might want to download the software and install it. even if your connection is fast the online demo can get sluggish a bit. The demo is mainly for the curious.

Step 1: Clicking stops and starts Dasher. The red line is the vector. The speed is controlled by controlling the length, the direction by changing the angle of the vactor.

Step 1

Step 2: “Drive” the vector towards the letter you want next. When you get closer to a letter it increases in size. Like magic, Dasher predicts the next letters you may be looking for and also spaces. Just go with the flow, think about what you are trying to write and let Dasher do the work.

Step 2

Step 3: When you get to a word that isn’t in Dashers dictionary, you might have some trouble. Just Dasher will do its best to help you but will also stay out of your way. I believe after using an unusual word once, Dasher adds it to the list so that prediction improves later on.

Step 3

Step 4: You will notice colors are helpful in Dasher. When you need a comma, period of other puctuation, aim for green. When you need a capital aim for yellow. For everything else colors just make it easier to distinguish what you are aiming for.

Conclusion: The guy who came up with the idea for Dasher is a freak’in genius! His name is David MacKay. The group of people who made Dasher what it is today are also very awesome.

Dasher
A very cool project –Dasher is a free text input program that uses a pointing device interface. I discovered this when my arthritis was at its worst and I began searching for anything that could help me.

It works like this: You control the speed by lengthening the pointer vector. You drive the vector towards the letter you want next. When you hit that letter you will see certain letter enlarge based on what dasher thinks you will need next.

It takes 30 minutes to learn Dasher. When I did learn it, I could enter text faster than typing.

Dasher is mainly for assisting physically disabled people interact with computers; this, in turn, helps them interact with the rest of us. In these applications the text can be fed directly into Text to Speech software (Text2Speech, T2S) giving these people the ability to talk!

There are joystick devices for people to control with their heads or whatever hand control they happen to have. There are also eye movement trackers; using special glasses and your eyeball you can control the pointer in Dasher. Imagine talking with your eyeball!

The people who developed Dasher could be charging for this software — but they don’t. They want people who need it to have it.

People who don’t need it should try it. Solidarity with the physically disabled — Dasher gives them an ability we take for granted. It is a good thing to see how others live.

I don’t need Dasher to input text. Even though I have only used a mouse to write with Dasher and my arthritis doesn’t actually bother my typing ability, I believe I have a better understanding and respect for people who do things despite disabilities. I also appreciate keyboard typing - I don’t take it for granted.

Try it!Dasher Java demo It’s actually pretty fun! Makes writing on a computer a kind of video game experience. :) Peace to all my disabled brothers and sisters — you are awesome!
