According to designboom ”based around a tablet holder with a central aluminum ring, the modular ‘ringO‘ system by vogel’s
combines device protection with an array of exchangeable stands and mounts, permitting easy viewing of the tablet.
Designed to permit use of usb ports, cameras, and other buttons when attached, ‘ringO’ device holders are available
for iPad, iPad 2 (while permitting use of apple’s magnetic screen cover), and samsung’s galaxy tab. the cases can be used on the back of the device to interface with other elements of the ‘ringO’ system, or placed over its front for safe transport.
The accessory mounts and stands that connect to the ‘ringO’ holders include the ‘wall mount’, which screws into the wall to hang a tablet for easy viewing; ‘flex mount’, which attaches to a wall but offers full tilt and swivel to offer a range
of viewing positions for the devices; ‘car mount’, which docks the tablet to the headrest of a carseat,
permitting second-row passengers to use it as a screen; and ‘adhesive mount’, which functions like the wall mount
but uses a strong adhesive rather than screws to stick to any unpainted, oil-free surface.
