Activity tracker
First Claim
1. An activity tracker for a user comprising:
- one or more sensors;
a voice user interface; and
a processing unit adapted to;
calculate total calories burned per day (TCB) and total calories intake per day (TCI) of the user;
calculate a daily calorie deficit (DCD) if TCB is greater than TCI or a daily calorie surplus (DCS) if TCI is greater than TCB, wherein DCD or DCS is a difference between TCB and TCI;
receive two weight measurements from the user;
calculate a measured weight change (mWT) between the two weight measurements;
calculate an equivalent weight change (eWT) based on an algebraic sum of the DCD and DCS for each day between the two weight measurements; and
automatically adjust a set of TCB scaling factors or a TCI scaling factor based on a comparison between the mWT and eWT;
wherein TCB is a weighted sum of basal calories burned during a day and calories burned corresponding to a plurality of physical activities of the user during the day, wherein weights of the weighted sum comprise the set of TCB scaling factors, and TCI is a sum of calories intake during the day multiplied by the TCI scaling factor;
wherein the calories burned corresponding to the plurality of physical activities are derived from measurement by the one or more sensors or a voice input to the voice user interface, and wherein the calories intake is derived from the voice input to the voice user interface.

Abstract
An electronic device tracks both calorie loss and intake for a user. The device comprises a plurality of sensors to measure user'"'"'s physical activities, and provides a user interface to allow user input of activities. The device tracks these activities and estimates the calorie burned based on predefined formulas. Also through the user interface, the device allows user to input information about food or drink consumption, and then estimates the corresponding calorie intake. User input of activities and food/drink consumption can be achieved by means of voice. The electronic device also runs a software app which can provide instructions for the user with regards to activities and/or food/drink consumption. In addition, the app allows user to enter weight, together with the tracked calorie intake and loss history data, to adaptively adjust the calorie calculation formulas and the associated parameters.
