1. A method comprising:
with a portable vital signs scanner having a plurality of different vital signs sensors,
receiving first motion data corresponding to a first motion of a user;
receiving second motion data corresponding to a second motion of the user, the second motion data indicating that the second motion is smaller than the first motion;
determining that a difference between the first motion data and the second motion data is greater than a predetermined threshold;
concurrently sensing data from a user with the plurality of different vital signs sensors over a period of time;
over the period of time, determining a plurality of different vital sign values for a respective plurality of different vital signs associated with the user in response to the sensed data from one or more of the plurality of different vital sign sensors; and
based on the difference determination between the first motion data and the second motion data, designating at least two vital sign values as valid;
fusing together at least two different vital sign values that were designated as valid to improve the quality of at least one vital sign value of a vital sign.
