This aide is applicable to Quadriplegic users that have no finger mobility, but that still retain arm/wrist mobility.

This pin that can slip into a normal OT sleeve. An OT sleeve is a material strap that attaches around the palm, and has a sleeve inside for slipping a spoon/knife (or stylus) into.

An apple pencil or regular stylus can then be attached. Please note that due to the conductive requirement of most stylus and phone, it is important that the stylus still touches the person fingers in order to conduct.

So you will need:
1) This model printed out.
2) OT sleeve
3) A stylus compatible with your device, and that can fit into the clip.
(You may need to scale the model up or down a bit if your stencil is wider/narrower)

I have uploaded a Lefthand and Righthand version.

I have two quadriplegic friends who use this gadget daily for accessing their phone.

I also add a pin-stick with a platform. You can either velcro or superglue this part to your phone's cover to hold in the other hand.

I also add a microphone platform. Again you can simply stick a phone-cover to this flat surface (or use Velcro). For this one you will need to go buy a microphone screw-top that fits your particular microphone stand, and then replace the top half with the platform.
