It would be nice to make use of them in openembedded !


###digital magnetic compass###
wince use: a program to show north or a destination selected in google maps
while using GPS

OE: It could e.g. be used in qlandkarte or similar program



###g-sensor###
wince use: *rotate the display automatically according to device orientation.
*e.g. opera browser can even be rotate 180° to provide the total *Pad
experience. You have to shake the device a little bit in order for rotation to
become active. Threshold to avoid accidental rotation.

OE: monitor g-sensor data and filter for rotation pattern to use xrandr to
*rotate display once Xorg is started.
*use it also to write fbcon_rotate state to procfs accoringly 
*include similar 'shaky threshold' like in wince
*make use of continuous rotation if possible for the ultimate Pad experience!


###ambient light sensor###
wince use: *set high display backlight level in bright areas, low in dark
areas.

OE: *Add (support in present) applets for various desktop environments like
gnome to switch between modes. Automatic sensor-data based backlight mode or
manual backlight mode user set with regulator.
*Alternatively add simple script with shortcut. E.g. tap an icon and then use
device's volume keys to set brightness during a given amount of time. awesome!


###proximity sensor###
wince use: *can detect when device is with display down on a surface or held on
ear for call. in wince this will send command to radio to switch between
speaker phone and handset mode.

OE: *do same thing in freesmartphone
