In the five years since losing both arms in an accident, Christian Kandlbauer had regained much of his cherished independence thanks to a high-tech, mind-controlled robotic limb. He even got a driving licence.
Now Mr Kandlbauer, 22, has died of injuries suffered when the car he was driving veered off the road and hit a tree. The cause of the crash is unknown - including whether the arm had anything to do with it.
"Don't live for others, live for yourself" Kandlbauer had written on his website, which on Friday was filled with condolences after hospital officials in the southern Austrian city of Graz said he did not recover from injuries sustained in Tuesday's accident.
Kandlbauer was the first person outside the United States to wear the innovative, robotic limb that recognised signals from his brain and moved accordingly, said Otto Bock of HealthCare Products GmbH that produced the prothesis.
With a normal prothesis for his right arm and the high-tech prosthesis in place of his left, Kandlbauer's daily life had largely returned to normal. He was able to get a job at a warehouse for a car repair shop and get his driving licence in October 2009.
"Thanks to the mind-controlled prothesis, I'm almost as independent and self-reliant as I was before my accident," he said in comments on the Otto Bock HealthCare Products GmbH website. "I can pretty much live the life before the accident."
For the prothesis to work, four of Kandlbauer's nerves were redirected to his left chest muscles, expert Hubert Egger was quoted as saying on the website.
To enable Kandlbauer to drive himself to work every morning, his Subaru Impreza was adapted with special equipment, including a modified emergency brake and a button to operate the horn, indicator lights and windshield wipers. It was approved by local transportation authorities.
Interviewed earlier this year by the BBC, he said he felt very happy with the high-tech arm. "It is like my earlier arm," Kandlbauer had said. "I feel that my arm is a part of my body."
He said he lost both arms when he was 17 after climbing up a utility pole and getting shocked by touching a power line in September 2005.
