Kevin commented on StairWalker 2.0 [Update: The Designer's Journey]

Hi Robert,
Thanks for fixing the videos. It is enlightening to see various people using the current prototype.
I noticed the handle bend in 3rd dimension. I understand the reason. Will it limit the use in situations where only one hand rail is present or in countries with opposite side traffic conventions?

Hi Robert,
I like the new sketches showing the use and new configuration of the cane handle.

Hi Robert,
I like Version 2.0!
It makes your device portable to more places where the user may need it.
A survey of existing handrails (shapes and materials) and building codes may be useful for refinements of the handle-to-shaft configuration. I think the round wooden handrail in my house would quickly acquire dents along its length very quickly.
