特殊用途
Dasher适用于无法使用双手键盘的计算机使用者 . 单手或没有手的用户可以使用 Dasher.
视觉是唯一必需的.
Dasher可以使用 鼠标, 触摸板(trackpad), 触摸屏(touchscreen), 轨迹球 (rollerball),或操纵杆 (joystick)
来操作- 任何可以取代鼠标的作用的两维的定点设备
. 足部或头部鼠标也可供选择.
它还可以用一个 眼球追踪系统操作, 构成一个完全不用手的输入系统
. 在一个小时的练习之后, 一些使用者就能用结合眼球追踪系统的Dasher以每分钟20个单词的速度进行输入.
想观看一个眼球追踪系统Dasher的视频示例,请参考
David Ward's
movie page. [在视频中, David 敲击空格键运行程序, 随后他只用眼睛来操作.]
与 眼球追踪系统 + 可视键盘 相比, Dasher 有以下优点
- 我从肩部以下瘫痪. 我需要什么来使用Dasher?
- 你有电脑么? (Linux 或 Windows) 能用头部鼠标(head-mouse)么? 或其他种类的鼠标?
也许一个能控制鼠标坐标的嘴部操控系统(mouth-stick)?
如果有, 只需 下载Dasher的最新版本, 就可以用Dasher输入了.
如果标准鼠标或头部鼠标不可用, 那你需要一个眼球追踪系统来操控鼠标.
我们使用的系统来自 Eyetech
叫做 Quickglance.
这里是一些给出有关非标准鼠标设备的信息的链接.
- 头部鼠标(Head-mouse) From MouseVision Inc: VisualMouse
(VM) software
- widely used by disabled people,
can be downloaded from www.mousevision.com
free of charge.
VM is a pointing device using a webcam that
recognizes head motion (with no gear on the head).
It works with
Windows 98/ME/2000. [23/8/02.]
- Smart-Nav Head mouse (was called TrackIR)
- GyroMouse - Free space mouse - good for people with limited reach - and could probably be used as a head mouse or foot mouse.
- Carpal tunnel-friendly mouse:
One Dasher-user recommends the hand-held IBM GlidePoint mouse.

I thought you might like to know that I have been running
the Linux version of Dasher on the Sony Playstation 2.
I used the Sony "Dance Mat" controller to control Dasher with my feet.
This is a relatively low-cost platform with a variety of controllers
available, some of which may suit certain disabilites.
