Scientists have invented a specially-equipped robot vacuum cleaner that can sense human emotions. The scientists say that the Roomba robot vacuum cleaner uses a special headband to capture bio electric signals from the forehead of a human user, and then infers stress from muscle tension readings.
The system involves a control software programme that reinterprets natural muscle tension as estimating the user's stress level, they add.
"Two distinct robotic behaviours corresponding to two extreme emotional states, either relaxed or stressed, are triggered when the stress reading reach a threshold. Robot actions are then influenced by these stress readings. When a person shows high stress (~levels 3 and 4), the robot enters its cleaning mode but moves away from the user so as not annoy them. When a person is relaxed (~level 1), the robot (if cleaning) approaches the person and then stops, simulating a pet sitting next to its owner. If the reading is in between these two levels, the robot continues operating in its current mode until the stress reading reaches a threshold," New Scientist magazine quoted the researchers as saying.
Telling about the unique feature of this system, the researchers said that the robot's behaviour is controlled by human emotion instead of any explicit commands.
Thus this vacuum cleaner is a real well equipped robot.

Offer from Sears...
Today, we all know that the world is suffering from a great economic crisis. This is due to the recession that takes place all over the world. If the economy of a country goes down, it is sure that there is more chance for the cost of many products to hike up. With this kind of trend, people get depressed, knowing that they could no longer afford certain purchases that they were able to afford before. But then, good news for everyone! I bumped into Sears and found out the great discount offers on fall and winter apparels, ranging from 75-80% off. What are you waiting for?
