I mocked up some toolbar icons in photoshop for the smart watch GUI today and tested them out on the display when I got home from school. I played around with colors until I found the perfect grey for the toolbar, and after setting some alignment and measurement standards form myself, created a concept GUI that I really like and will stick with in the final software. The icons from right to left are the charging icon, bluetooth connected icon, and bluetooth disconnected icon. Obviously both bluetooth icons won't be on at the same time, but rather with boolean connection values coming from the Nordic nRF8001 will reflect the current bluetooth state of the watch. The time from the DS1307 and temperature from the IMUduinoBTLE's barometer will appear on all non-watch face screens, and will disappear when switched to a time face. When showing a time face after waking with a tap, pressing the side button will show the toolbar and show the number of notifications and the information mentioned above.
