New software modulates device notifications through reading brain waves

Designed to read minds, a new software can provide the proper notifications to users at the right time and situation based on cognitive state in handling multiple situations. Computer scientists from Tufts University in the United States have developed a system that can modulate intense notifications from wearable devices to allow users focus on a single task.

According to a study, researchers developed the "Phylter" system, which helps the user to receive notifications only when they are in the proper cognitive state to handle additional information. The system uses functional near-infrared spectroscopy, or fNIS, a neuroimaging technology that direct or indirectly monitor brain activity.

The system works with a monitor placed on the forehead of the user which shoots beam of light into the brain. The Phylter system receives streaming data about the cognitive state of the user and works to modulate whether the user should receive the information or it will wait, the authors stated.

An algorithm tailored to the brain waves of specific users is used to analyse the data from the device. The system will process the fNIS activity to identify the current situation if notifications could disrupt the user in work or social interactions.

In the study, Phylter was tested with the Google Glass, which users were encouraged to use to play video games. While playing, the participants received floods of notifications that the system started to work and analyse the activity. The system would deliver notifications to users precisely when they have the time and capacity to perceive it, researchers said.

The Phylter software, the researchers hope, would be useful in the future for people to manage distractions in their everyday activities. “It serves as a framework to prevent information overload by modulating the display of notifications to the user."
