*Full Disclosure: I work for Hillcrest Labs* We've recently released a consumer version of our "Loop" pointer. http://www.amazon.com/dp/B001U1LX3Q/ref=cm_sw_su_dp
It shows up as a standard USB HID Mouse, and therefore it will 'Just work' with basically any OS that supports USB mice. It definitely has the range to pick up across a large lecture hall, and it will let you move your hand pretty naturally to control the pointer on screen. (It also has a 'park' button which will stop mouse movement in case you feel like getting gesture happy.) It will map to standard mouse buttons (not spacebar), but you could remap these in your X configuration if you like. In addition to being a pretty good presentation pointer, this thing is hackable: we have an LGPL driver (http://libfreespace.hillcrestlabs.com/ ) which will get you access to all of the accelerometer and motion data that the device pushes out. (If you just want to use it as a mouse, you don't need this driver). --Christopher Conroy On Fri, Sep 4, 2009 at 9:53 AM, J.
