Very!
I have to wonder how much more difficult it would be for a person who may not have full use of his legs, as the guy in the demo obviously does.
Seems ironic that Dean Kamen, inventor of the Segway, chose to go after the mass market rather than specializing in this application where so many of his other inventions have been successful.
Socialism/Communism will end the development of all advances like this for ev everyone who needs it.
Interesting but the market I see would be rather small. Most young amputees can be fit with prosthetics eminently more functional than this. Older amputees such as those who lost limbs due to diabetes would find it problematic to use the hip control devices. Same thing for paraplegics. I’ve seen similar device prototypes that double as an electric wheelchair but will elevate to a standing position that seem more practical.
Neat idea for the few that could use it though.
Stairs?
What if he drops his briefcase? How does he bend over to pick it up?
What if the thing falls over? That’s a long way to fall. Serious injuries will result.
I think a wheelchair still beats it.
