Computer today become the multi function tools that used by
human life. The engineer at MIT try to make the supercomputer that can
detect overworked human brain. It detects the cells of brain if they are
working too hard or overworked. Brainput Multitasking Assistant A volunteer
tries out the Brainput workload-sensor and multitasking-helper. Your office
mates, whether they’re people or pets, can probably tell when you’re feeling
stretched too thin — heavy sighs, hand-wringing and general signs of stress are
fairly easy to spot.
It will be very useful and great invention in computer and science section.
Otherwise, now a new brain supercomputer interface could turn your computer
into a more sympathetic partner, taking over some of
your task when it senses you’re overworked. The system, called Brainput, is designed to detect when
a person’s workload becomes excessive and to modify said workload to make it
easier. Erin Treacy, a postdoc at MIT, uses functional near-infrared
spectroscopy to monitor brain activity and aid this brain and computer
interaction.
Erin Treacy and her colleagues used the fNIRS to determine when a person
was multitasking, analyzing brain signals in earlier experiments to isolate
patterns of activity. They could distinguish three specific states of
multitasking, and developed classification algorithms for these patterns. The
system works by strapping a fNIRS sensor on a user’s forehead — because hair
interferes with the signal, for one thing, and also because the area tracks the
anterior prefrontal cortex, which is involved in high-level processing. Solovey
and colleagues used Brainput with virtual advanced robot, which were designed
to adapt to the mental states of a dozen human volunteers.
The
volunteers had to send a pair of advanced robot
through a maze to find a WiFi signal, continually switching between
both advanced robot to keep them on the right paths and prevent them from
crashing. As the volunteers’ brains began in a specific type of multitasking —
a detectable state of activity known as branching — the technology of
robot took on more of the work, such a system could guard against distracted
drivers by helping out when a person’s attention is just too divided. Or it
could help workers who must juggle several tasks at once, perhaps air traffic
controllers. In any activity involving multitasking or information overload, we
could expect to see improvements in the user’s performance and experience.
