Wheelchairs have innovated throughout the years. From hand operated, to electric, and now a voice activated and controlled wheelchair is also possible.
Although the short video below is in Hebrew, it presents an individual controlling the wheelchair used by voice commands alone. He speaks to a microphone stating ‘right’, ‘left’ to navigate respectively, ‘forward’ to go straight, and ‘enough’ when it desires the wheelchair to stop turning.
The HM 2007 speech recognition system was connected to the wheelchair, and it seems to be taking orders pretty efficiently.
I am not certain if this is yet effective enough to be mass produced, but I am sure that those with increased disabilities may see a great need of a wheelchair such as this.
