We have been estimating our mental energy and have found a few insights based on understanding the problems of:

  • Overworking our brain while working from home
  • Thinking too much when in a conversation
  • Being unable to properly understand our mental “fuel”

We have built a quiet interface (pay attention to it when you want to) to help understand in real-time your change in brain activity. We provide this through a head-up feedback LED with a continuously adjusting colour as shown below!

Estimating Mental Energy

Building upon the head-up feedback we have been attempting to understand how our mental energy state changes throughout the day and how that could relate to our circadian rhythm.

For a background around circadian rhythms from the NIH click here. On average we have two energy cycles within a day. Depending if we are a night or day person we may have our 1st peak occur during the morning or early afternoon.

To show how we are currently estimating mental energy we have taken single subject data over the course of multiple days, predicted the energy scoring throughout the day, and computed an individual’s “average energy across the day”, which is a plot of how, on average, that individual’s estimated mental energy levels change throughout the day.

Below are two of these plots, each for a different subject:

On average we have found across some of our early testers one of the best times to start a work session is 10am.

Here is an example of the web dashboard in it’s current form for more real-time throughout the day insight:
