ActivityMonitoring-CoverAs one of the assignments of the Data Analysis Coursera class, participants were asked to detect movement type from the sensor data of a smartphone. When I did the assignment, I created the report in Markdown, and converted it using Pandoc. This process was much like I described in an earlier post.

Recently, Anneleen Maelfeyt has created a document style and logo for texts by Data Intuitive which I converted to a LaTeX template. As a proof of concept, I compiled the Markdown file with the new template. If you’re reading on a screen (including tablets), use this version: ActivityMonitoring-Screen. For printing, there’s a version with a modified cover and A4 paper size: ActivityMonitoring-Print.

An excerpt from the introduction in Markdown format:

Smartphones are ubiquitous, partly because they enhance our 
lives in many ways. Most recent smartphones have a so-called 
accelerometer[^1]. This device measure acceleration in 
3 directions and in some cases also rotation by means of a 
gyroscope[^1a].

A relatively recent phenomenon is that smartphones 
(or the applications that run on them) attempt to be 
aware of the user *context* in the broad sense: location, 
movement, mood, schedule for the day, etc[^2].

One aspect of detecting the context of the user is movement 
and activity. Detecting whether someone is walking or sitting 
down makes a big difference for all sort of things: interests, 
way of interacting with the device (only thumb or more fingers?),
etc.[^3]

By the way, the Data Analysis course runs again starting the end of October. I highly recommend it.
