very special assistive technology

"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

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

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 electronics development company based in the East Midlands of England that designs extremely sensitive equipment to better connect the disabled user to their computer, gaming systems or environment.

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

Our Feather joystick/ mouse pushes the bounds of what is possible in terms of light force operation and is the world's lightest.

With the introduction of the unique self-adjusting G-Click and I-Click switches, we continue to develop ultra-sensitive devices unmatched by any other product.

Small companies in rural Leicestershire, manufacture our products whilst we concentrate on support and future developments.

We enjoy designing our special products and helping individuals with individual challenges in the UK and worldwide.

Thank you for your interest.

The I-Click switch is an infrared muscle twitch sensor that like its sister product the G-Click provides class-leading sensitivity.  This technology was made famous by the late professor Hawkin.

The I-Click is provided with optional mounting kits chosen to suit its precise use, most often for detecting muscle twitches on the user's face.

Setting up the I-Click is made carer friendly by its live position indicated on the built-in multicolour led bar.

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

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

With a G-Click the sensor is mounted normally on you, it self-adjusts to compensate for your current position and then continues to 'just work' all day long with no further adjustments, even if the user's hand is accidentally moved.
