Optimizing Apps for Wearables With Enlightenment Foundation Libraries
Developers looking to add GUIs to their embedded devices have a variety of open source and commercial options, with Qt generally leading the list. If you’re operating in severely constrained environments, however, especially for battery powered devices like wearables, the open source Enlightenment Foundation Libraries (EFL) should be given close consideration.
At the recent Embedded Linux Conference, Cedric Bail, a long-time contributor to the Enlightenment project who works on EFL integration with Tizen at Samsung Open Source Group, discussed some of the lessons learned in optimizing wearable apps for low battery, memory, and CPU usage. Bail summarized EFL and revealed an ongoing project to improve EFL’s scene graph. However, most of the lessons are relevant to anyone optimizing for wearables on any platform (see the ELC video below).
