Video demos for the following devices:

1. Ergonomic Touchless Keyboard

A bendy straw can do the key hitting and give arthritis hands the lightest stimuli

You can use a bendy straw to type. You won't feel any hitting force on your arthritis finger or bending pressure of the wrist. You can move the bendy straw as fast as you like without causing unintended key hits.

The head of the bendy straw needs to be opaque. In this demo, a black tape is wrapped around the head of the bendy straw to block the light and also protect the straw so it can last a long time.

Hands with arthritis can type fast without pain too.

The most comfortable posture?

Holding this keyboard in one hand, resting it on a lap, make yourself comfortable. Your arms are dropped naturally and supported by your lap so that your shoulders are minimally loaded. This posture avoids a lot of the body strain, especially for the shoulder and wrists. If you don't want to use fingers, use a pencil instead.

2. Touchless Keyboard-mini

Bendy straw Operation gives hands the most relief.

You can use a bendy straw to type. You won't feel any hitting force on your finger or bending pressure of the wrist. You can move the bendy straw as fast as you like without causing unintended key hits.

The head of the bendy straw needs to be opaque. In this case, a small piece of paper (a shopping receipt) is rolled into a stick and inserted into the bendy straw.

The most comfortable posture?

Holding this keyboard in one hand, resting it on alap, makeyourself comfortable, and use fingers of another hand... This posture avoids a lot of the body strain.

If you don't want to use fingers, use a pencil instead.

This can be faster than a full sized keyboard, if you practise...
