My principal interest in mobile applications is to push the boundaries of innovation to create uniquely mobile experiences. I hope my blogs excite and challenge developers to think 'outside the box'.

Heart Controlled Mobile Interaction

I have been working on a project recently called Heart Angel with Carlos Garcie Wylie exploring the use of an Alive Technologies ECG Heart Rate monitor with an N95. This type of idea has been discussed before by fellow Champion Arto Holpainen but my interests have been primarily in the visualisation of the information gathered through exertion mapping. Heart Angel The application incorporates two cardio respiratory tests, an independent monitoring application "Jog-Free", as well as a simple mini-game (I couldn’t not try to make a game out of this Wink). The follow video shows the cardio vascular test which are the ‘Tecumseh Step-Test’ and the ‘Rockport Test’ both widely used methods for ascertain fitness levels by the medical profession.

   

The mini game  has a simple  "Space Invaders" theme which makes use of the players Heart Rate. At random intervals the player is prompted with a 'Bonus-Screen' at which time they should aim to raise their Heart Rate by 10beats/min. If successful the player is awarded a bonus, otherwise the game simply resumes. He following video illustrates the idea.

 

Finally and the main point of our interest is the so-called jog-free mode which allows us to collect heart rate along with GPS position to produce exertion maps such as the one shown.

The user here is going anti-clockwise around the course and many of the high exertion points represent hills.

I want to extend this to use terrain gradient within the maps to get a better visualisation and possibly test the application with climbers using 3-D spatial mapping. Anyway I will bring this along to the Innovation workshop before the S60 Summit in Barcelona if anyone wants to playLaughing .
