Half-Life

How fast does your own attention fall off inside this world?

This experiment has no synthetic data. It reads the dwell times this session has actually recorded — how long you stayed near each artifact, in order — and fits an exponential decay to them by least squares on the log of dwell time.

Explore more of the world and come back. The fit changes because your data changed. If you have not looked at enough things yet, it says so instead of showing a curve.

Reports the fitted half-life in seconds and the number of samples it was fitted from. With fewer than four dwell samples it reports insufficient data rather than a number.

The figure shown under the canvas is computed by the run above, in this tab, from the settings currently selected. Change a control and it is recomputed. Nothing on this page is a stored or illustrative value.
