Microsoft develops emotion-reading smart bra with Windows Phone app


We know wearables are going to be the next big thing, but Microsoft Research has taken it to an entirely new direction.

Neowin reports that they have created a new bra laden with sensors which read things such as your heart rhythm,  skin conductance, and even movement via a 3 axis accelerometer and two axis gyroscope.

The data is then used to build up a picture of a users emotional state, after they spend some time calibrating it.

Data is transmitted via Bluetooth to a user’s smartphone, and from there to the cloud.



The EmoTree app will also let users record their meals and stress levels before then, and will ultimately allow users to detect stress-related overeating, and advise users on other psychological methods to manage this such as deep breathing exercise, tapping on the screen for each 10-second breath they took, ten times over.


A bra was chosen as the ECG could be taken from closer to the heart, and the system worked less well in men where sensors were further away.

Overall 87.5% of participants reported that they “became more aware of their emotions” and how they related to their eating habits, but only 37.5% reported that their eating patterns changed as a result of the emotional awareness and logging of food intake. The sensors in the bra, meanwhile, performed well during the research period, with over 72% accuracy.

While such a system is unlikely to hit the mainstream, it is of note that Microsoft was working similar technologies into their Kinect gaming products, where reading a gamer’s emotional state may be used to ramp up or down the action level of a game based on how entertained they are.
