|The Focus of the Study Was to Estimate Energy Expenditure Thanks to Accelerometry Data Collected by a Smartphone.||Device: Energy expenditure estimation||Not Applicable|
There is a growing interest in evaluating physical activity and energy expenditure (EE) to provide feedback to the user. The use of mass-market sensors such as accelerometers offers a promising solution for the general public due to the growing smartphone market over the last decade.
Thus, the proposed EE estimation function has been created using accelerometry data collected from 10 volunteers equipped with a smartphone and two research sensors (Armband and Actiheart) used to estimate EE during several controlled activities. The research sensors' data serves as reference during the creation and evaluation of the proposed function.
It has been evaluated with data of 6 other volunteers in free-living conditions in the previous eMouve project.
eMouve2 consists in acquiring more data from 24 new volunteers in order to validate the function in free-living conditions.
This EE estimation function using the smartphone technology is dedicated to light- and moderate-intensity activities, and we believe it can be a new way to help people controlling their daily physical activity level.

|Study Start Date :||April 2013|
|Actual Primary Completion Date :||June 2013|
|Actual Study Completion Date :||October 2013|
|Experimental: Free-living conditions||
Device: Energy expenditure estimation
Volunteers were asked to wear sensors during about 12 hours, one day. They wore 2 research sensors that estimate energy expenditure: Armband and Actiheart. They also wore a smartphone (in a front pant pocket) that collected accelerometry data.
- Accelerometry [ Time Frame: about 17Hz (duration: about 12 hours) ]Measures acquired by a smartphone (it contains several sensors, including a tri-axial accelerometer)
- Energy expenditure [ Time Frame: one point recorded each minute for about 12 hours ]Sensor: Armband
- Energy expenditure [ Time Frame: one point recorded each minute for about 12 hours ]Sensor: Actiheart
