Multi-Modal Activity Parameter Estimation

原文（中国語）

In one embodiment, a method includes determining a set of one or more step-based activity parameters to estimate for a current activity of a user; and determining current parameter-estimation inputs including (1) a current activity context and (2) a current status of each of a number of sensor modalities. The method further includes selecting, for each of the one or more step-based activity parameters and based on the current parameter-estimation inputs, a respective set of one or more sensor modalities from the number of sensor modalities to use to estimate that step-based activity parameter of the current activity of the user; and for each of the one or more step-based activity parameters, estimating that activity parameter using current data from the respective selected set of one or more sensor modalities.
