The goal of this project is to create intelligent, collaborative and interactive outdoor information displays.
Recently, digital information pillars have become increasingly popular. They offer the possibility of presenting a wide variety of content on a single information medium. This results in many new business models - for example in the field of advertising, the presentation of knowledge in museums or also for the presentation of current information in the public sector.
Up to now, however, these information pillars have mainly been used indoors and are equipped with few to no interaction options. This project aims to develop a pillar that (a) can be used both indoors and outdoors, that (b) allows user interaction - in particular those that go beyond pure touch gestures - and that (c) can display context- and history-dependent information through networking and collaboration with other pillars.
In the outdoor area, the pillars are exposed to strong fluctuations in temperature, humidity and air pressure (up to 50°C difference on one day). This requires particularly hardened IT and sensor technology. Due to the most varied light conditions to be expected, weather/context-dependent displays of information and interaction metaphors may be necessary.
Conceptually, a variety of metaphors exist for user interaction - from speech to gestures to biometric signals. For the stelae, this poses particular challenges due to weather conditions, the potentially large numbers of rapidly changing viewers and, of course, data protection.
For collaboration, it is necessary that the stelae can exchange information with each other and correlate it. For example, a common picture of the environments (e.g. where is which stele, who is where) must be created. Especially for the history-dependent display, data protection plays an essential role, as this often involves user-related data and at the same time it is not easy to decide who is currently interacting with the stele.
