The Smart Light represents a completely new human-machine interface, making existing online and mobile services graspable and omnipresent everywhere, and creating the basis for completely new applications and services. This large-scale public display can present any kind of digital media and is enhanced with numerous sensors and communication interfaces, making it capable of serving as an interactive communication centre for all kinds of services and applications.
Being equipped with wireless network communication, users can connect to the Smart Light and share or download all kinds of data. This includes take-away of commercial data, or sharing of private data in a closed or open social network. Even spontaneous local networks can be created which e.g. allow sharing of taken pictures or video clips at events like concerts, festivals, etc. The Smart Light supports the use of any mobile device like cell phones, smartphones or tablets.
Being aware of its environment, the Smart Light can estimate the attention level it is given by analysing behavior and body posture of bypassers. This estimation allows to analyze the interest of individuals regarding the displayed content and to change the content according to personal preferences. This evaluation can further be used for evaluation of the displayed data, e.g. measure how much attention is given to different commercials, thus enabling new pay-per-view billing standards for advertisers. As well, the attention level can be used as an important input regarding the control of interactive systems like automatic kiosks. The estimated attention level can be used to deduce how comfortable users are in the usage of the system and offer help dialogues for novices or provide short-cuts through the menues for experienced users.
The numerous sensors in the Smart Light enable an interaction with people and their mobile devices in the range of the display. This can happen explicitly, if people actively communicate with the Smart Light e.g. via hand-gestures or smartphones, or implicitly, initiated by the Smart Light if people are detected in its environment (e.g. pushing news of subscribed services like sport results or stock rates, automatic content adaption). The combination of these principles allow a completely new form of mobile services like content sharing and creation of spontaneous social networks which only depend on the current location and time.
The Smart Light gives the audience the opportunity to dispose unwanted and unrelevant advertisements and instead offers displayed content which is adapted to personal preferences. The user can set up a profile which can be stored on mobile devices and which automatically signals the Smart Light to accommodate to the specific user, and to display information which may be interesting and relevant.
Single Smart Lights can be combined into a network of displays which communicate and share data as well as services. This allows the collaborative Smart Light System to reidentify individuals in a distributed environment. This enables special applications like guiding systems which know where each individual is headed, or content which follows people on their path along various Smart Lights.
