Denoting b as b=[b 1,b 2,...,b P ] T and the estimated metric-vector as b| T, we have {mathbf{b}}left| _{mathrm{T}}} right.
Visual outputs are then fused with the inertial measurements using an Extended Kalman Filter (EKF) to estimate metric speed, distance to the scene and also acceleration biases.
Only in the latter case should we expect a substantial relationship between the accuracy with which participants estimate metric spatial properties and their SOD.
Math activities focus on developing basic skills using science information related to a specific unit for example, estimating metric measures, solving number puzzles, and creating and using graphs.
