AttentivU Glasses V2

ATTENTIVU GLASSES VERSION 2

2020 - ongoing

AttentivU Glasses V2 is an updated version of our previous pair of glasses, AttentivU. It senses brain activity using electroencephalography (EEG) and eye movements using electrooculography (EOG) in order to measure different cognitive processes in real time, including cognitive load, fatigue, engagement, and focus (please check our FAQ on this page for the definitions). The device can be used for passive or active interventions: to monitor the state of the user, provide gentle audio or haptic feedback when the user is less attentive, or adapt the environment when cognitive overload is detected by blocking notifications. The system can operate in a standalone, non-networked fashion to ensure privacy of the collected data. The use of the AttentivU glasses can be limited to just those moments when the user decides they want to learn to sustain their attention.

We have tested the first generation prototype of the device in the workplace and in learning settings with over 100 subjects. We performed experiments with people studying or working by themselves, viewing online lectures as well as listening to a professor at the university. We have now completed the first test of the glasses prototype with more than 30 subjects who were performing a driving task in a simulator overnight when their attention waned, and the system reminded them with a sound or with a vibration to pay attention to the road . This research paper was rewarded with the honorable mention award at the 2019 AutoUI conference. Please check the dedicated page about the car use case scenarios on the MIT website.

The new version of the glasses is lighter than the previous version, has a new PCB, a longer battery life, and WiFi in addition to Bluetooth.
