Hi Christos,
[Sorry if you've already aware of or considered some if these!]
If you haven't already, you could consider the Bluetooth integration options (subject to agreement from powerchair provider):
R-Net: Install powerchair Bluetooth module
DX: DX ECU Unit + Tecla
https://dynamiccontrols.com/en/downloads/dx/dx-auxilliary-modules/36-ecu-installation-manual/file
https://gettecla.com/products/tecla-shield
Powerchair second joystick options:
*Mini* PointIt (the small black one)

Mounting plate fixing on the base, possibly use removable mount on powerchair. If you did look at a switch for left click etc rather than dwell, note that the switch ports are on the outside faces which can be a problem if it is mounted on the outside of the powerchair - they are susceptible to damage
Modified BJOY Chin Switch
We have used a couple of these recently as the switch ports can be orientated so the cables connect from the front and rear of the joystick. Currently a special available from SmartBox. Chin switches are not mounted as shown, external switches can be plugged into the side of the unit

We are also evaluating these:

We've actually moved away from using the BJOY ring (both versions). It is a great idea but:
- It raises the height of the joystick
- Even replacing the grub screws with a good quality pointed tip grub screw and using Loctite, they can still come loose
- Orientation change of the chair (using tilt or being used on an incline) can cause the cursor to drift up or down the screen depending on orientation.
Hope that helps,
Paul

Subject: Joystick mouse mounting challenge
Hello everybody,
I have spent a lot of time looking for a solution to my challenge and I thought of asking the group the question before either spendind a lot of money, or trying to build something myself...
We have seen a gentleman with CP who is a powered wheelchair user (right hand joystick). We have seen him for a computer access assessment. After trying a few things, it seems that an Optima Joystick from Inclusive and some kind of OSK with dwell function would be ideal for him. During the assessment, I held the joystick in an area roughly to the right of his wheelchair joystick (so on the inside of his wheelchair) and his control and selections were very good. He was pleased with selecting speed.
My initial thought was to mount this joystick somehow on his desk, in a way safe for him to drive his wheelchair close to the desk and then use it. I have looked for hinged and telescopic shelves but can find something that would work for him.
Although he is very accurate with his driving, ideally, the mouse joystick should be out of his way during his approach to the desk and then (somehow) put it in place for PC use. (but this is not that necessary)
I have seen this from inclusive: "http://www.inclusive.co.uk/bjoy-ring-wireless" which may be an option but just wondering if anybody had any other (more cost effective and practical) ideas.
Many thanks!
