40bits/s from 100cm away, cool hack.

• dralley 9y ago
  Why would they say 100cm instead of just... 1 meter...
  • grzm 9y ago
    One reason is to convey precision.
  • funcSoulBrother 9y ago
    The unit indicates the precision at which the scale is represented. So for this, the distribution is probably not very useful at a resolution of 0m, 1m, and 2m and is normalized between the 0 and 1XXcm range.

    Because the other distances are less than 1m and measured in cm, like 20cm, 50cm, etc. See their paper.
