"Celtic 'is a magic bag, into which anything may be put, and out of which almost anything may come."  

J.R.R. Tolkien

The Feather USB joystick/mouse uses magnetic levitation to offer an unparalleled force of less than five grams that we believe makes it the most sensitive moving joystick in the world.

The Feather can be supplied as an advanced PC / Mac / IPad* / Android compatible mouse or as a joystick, including gaming options.

* Latest IPads with USB  C  

Hypersensitive Joystick or Mouse

The Feather is designed to be the very lightest possible. 


The force to operate it can be set between twenty grams down to an incredibly light five grams.

Coupled with the ability to configure the Feather using the free app to suit the user, the Feather offers an opportunity for users familiar with controlling computers using a mouse or trackball, to continue to do so without resorting to eye gaze systems.


"Wow, this is THE lightest thing I've ever used, its wonderful, so smooth and accurate"  BJ  



Need an advanced Sip and Puff

Computer Controller? HAPP 100 gives fast & super precise control for​...

  • Scrolling

Control your computer by breath only

We believe that the HAPP 100 is the most advanced Sip and Puff (breath) controller available in the market today. With options to operate other assistive systems such as environmental control.~



"The HAPP is really good, I use it everyday.  This has improved my life in communicating (including writing this credit!) and doing things myself rather than ask my carers to do it. I can now search the web, chat to my friends and play games.  It allows me to have some privacy and independence that I didn't have before."  BF

about us

We are a small UK company based in the East Midlands of England that design and build equipment to better connect the disabled user to their computer, gaming system or environment.

In early 2013 we started with the most advanced sip & puff computer controller available to this day the HAPP100.

Our Games control Mixer (GCM100) is aimed at very advanced gaming as well as basic computer control and has a range of unique input options to tune it to the user's precise needs, and our Feather joysticks push the bounds of what is possible in terms of light force operation.

We continue to enjoy developing our unique products and offer support to individuals locally and worldwide.

Thank you for your interest.

G-Click is a new type of self-adjusting tilt switch, by using a solid-state gyroscopic it also offers zero force operation.

This improves on traditional mechanical switches by automatically adjusting, thus being in a perfect position at all times.

With a G-Click the sensor is mounted normally on you, and self adjusts to compensate for your current position, and continues to 'just work' all day long with no further adjustments.
