Can you make one or two continuous gestures? If you can operate a joystick, mouse, trackpad, or rollerball, then you have a two-dimensional control. If you can point on a touch-screen then that's perfect too. Can you move your nose around? If you can shake your head, that's a one-dimensional control; if you can nod, that's two. A head-mouse can be quite cheap, and it is a convenient way to drive Dasher. (We recommend the SmartNav3 from NaturalPoint, which costs about $200, and works under microsoft windows only; this device used to be called the NavPoint TrackIR until 2002, when that brand name was transferred to a different device. We also recommend the Origin instruments Headmouse Extreme, which costs about $1000; it works as a USB mouse on any computer.) Can you waggle one finger or one foot? These head-mice can be used to track fingers and feet as well as heads.

Mugimendu jarraitu bat edo bi egin ditzakezu? Kontrol-palanka, sagua, trackpad edo rollerball bat erabil badezakezu, bi dimentsioko kontrola duzu. Ukipen-pantaila batean seinala badezakezu, oso ondo dago. Sudurra mugi dezakezu? Burua astindu badezakezu, dimentsio bakarreko kontrola da; baiezko keinua egin badezakezu, bi dimentsiokoa. Buru-sagu bat nahiko merkea izan daiteke, eta Dasher gidatzeko modu oso egokia. (NaturalPoint-en SmartNav3 gomendatzen dugu, 170 € inguru balio du, eta Microsoft Windows-en bakarrik egiten du lan; 2002 arte NavPoint TrackIR izenez ezagutzen zen, baina gero beste gailu bati jarri zioten izen hori. Era berean, Origin instruments-en Headmouse Extreme ere gomendatzen dugu; 850 € inguru balio du, eta USB sagu gisa jarduten du edozein ordenagailutan.) Behatz edo oin bat mugi dezakezu? Buru-sagu hau behatzak, oinak nahiz buruak jarraitzeko erabil daitezke. SmartNav3 eta Headmouse Extreme alderatzeko, ikus http://www.inference.phy.cam.ac.uk/dasher/Headmouse.html.
