I spent part of my week-end finishing the voice recognition sub-system, tweaking E.V.E’s UX and cleaning up E.V.E \/ A.D.A.M code.<\/p>\n

Let’s see how it went !<\/p>\n

E.V.E loves snakes<\/strong><\/p>\n

E.V.E’s interface is based on HTML5\/Javascript and runs inside a browser. I wasn’t too happy<\/a> with my RPi’s browsers until I settled for Epiphany<\/a>. Even then, I had to write a little script to simulate a F11<\/code> key press to run the browser in fullscreen mode.<\/p>\n

And actually I didn’t really need a full browser. Since I was happy with Epiphany’s webkit<\/a>, I decided to strip E.V.E to a bare minimum (so to speak …).<\/p>\n

I wrote down a few lines of python and used the WebKit python binding to create a simple web view, the size of my RPi touchscreen (800 x 480):<\/p>\n

\"eve-python\"<\/p>\n

Simple and effective. It runs E.V.E perfectly well and is much faster to launch.<\/p>\n

The only drawback was the annoying presence of the Window Manager (OpenBox<\/a>) decorations around the window. So, I edited ~\/.config\/openbox\/lxde-pi-rc.xml<\/code> and added these lines to remove all window decorations for “eve.py”:<\/p>\n

<application name=\"eve.py\">
\n  <decor>no<\/decor>
\n<\/application>
\n<\/code><\/p>\n

E.V.E now boots up much faster, and the unnecessary clutter of a full browser is now removed.<\/p>\n

Tweaking E.V.E’s interface<\/b><\/p>\n

After a couple of weeks playing with E.V.E’s touch interface, I felt I had to tweak its UX a bit:<\/p>\n
