Placing information at specific locations in the home provides rich and intuitive ways for people to cope with information, as they leverage semantics of the locations within the home. However, there is no deeper investigation yet on how users would embed digital cloud-based information into various locations in their homes, partly because previous systems were not robust enough to be deployed in real settings for an extended period of time. To this end, we have developed PostBits, a system of display blocks that integrate cloud information with contextually rich physical space. PostBits were designed for long battery life, robust communication and simple interactions, to enable a field deployment.
