Wearables are typically composed of a belt or back pack PC, see-though or see-around head mounted display (HMD), wireless communications hardware and an input device such as touchpad or chording keyboard. A crucial question is how to best use these devices to create an intuitive interface for the user.

The HIT Lab has been experimenting with body-stabilized spatial information displays on a wearable platform and have found that users perform faster with a spatial display and are able to remember more displayed information.
