In the joint project VIGITIA, the project partners are investigating how projected augmented reality (PAR) can support and enrich everyday interactions around tables.

In PAR, one or more cameras record the table surface and objects on it in real time. A projector mounted on the ceiling or on a swivel arm can thus project onto the tabletop or objects with millimeter precision and without distortion. This makes it possible to fade in additional information and interaction possibilities for the objects and to support analog work processes. Parallel to this, it is nevertheless possible to seamlessly integrate existing, intelligent objects such as smartphones, tablets or laptops into the system, for example, in order to exchange data between the devices via the projection as an intermediary or to offer a larger interaction surface for several people than the small smartphone screen allows. Here, the technology takes a back seat and instead the focus is on the shared experience, which is only supported by the technology if desired.

Tom is 34, and has a wife and three children. He is a househusband, an amateur musician and is involved in several social projects and associations.

The morning did not go well at all. In the morning, he forgot the eggs on the stove, child 1 spilled cocoa all over his exercise book. Child 2 missed the school bus, but the car key is nowhere to be found. Then Tom tries to wrap child 3's birthday present for a friend nicely. Despite all the helpful YouTube videos, all that has emerged is a shapeless lump.

A package arrives late in the morning. Inside: the long-awaited SmartProjectorLamp™. This is screwed into a normal lamp socket above the table. It integrates a daylight projector with multiple cameras that detect what's happening on the table below them. A small enclosed box - the battery-powered SensingMobileController™ - is taped under the tabletop. With a quick tap on the tabletop, Tom wakes up the devices. They automatically synchronize and calibrate, and after a few seconds the SmartProjectorLamp™ projects an interactive tour of the features of the now interactive table onto the tabletop.

After Tom finishes the tour, he decides to put his new old table to productive use right away. He superimposes a projected ruler on the table to help him cut the wrapping paper straight and to the right length. Now the birthday present looks much better.

When cooking lunch, the table supports him with superimposed timers. When Tom puts the sweet potatoes on the table, it automatically shows him preparation instructions.

Child 3 comes home. Tom moves it to wipe the table by starting a little game on it where you have to wipe away dirt monsters projected on the table. Next, another game on the table shows the positions of plates and cutlery and measures how quickly and accurately you set the table. Child 3 sets the table again several times in order to beat his own high score. Tom has to intervene so that everyone can finally eat.

After dinner, homework is done. Child 1 has forgotten the physics booklet at school - and the school assignment is due tomorrow. The mother of a schoolmate has sent the scanned pages via WhatsApp. Tom puts his smartphone on the table, which immediately recognizes it and displays the latest images on it as thumbnails next to it. Tom drags the relevant pictures to the center of the table, where they automatically arrange themselves into a stack. Child 1 can now flip through the virtual notebook on the table. A scanned worksheet must be printed out again. Tom displays the printer icon on the table and drags the image onto it.

Child 2 has a world map projected on the table to help him with his geography homework. Child 3 is fascinated by it and places Lego men in all the countries he would like to visit.

In the early evening, some neighbors still come by to discuss solutions for the ailing playground in the settlement. One of them has brought along a “Group Mirror” application on his tablet to support and guide discussions. Among other things, this shows next to each person at the table how long they have been talking. As a result, everyone can see that Tom is very much dominating the conversation at the moment. He decides to back off a bit and give the other participants more space to make their points. When everyone agrees, the plan is put in writing and a scan is made of the table, which is automatically sent to everyone present.

After the neighbors leave, Tom receives a call from Sebastian, a college friend who also owns a SmartProjectorLamp™. The two decide to play a board game together with their families: To do this, they both start telepresence mode on their tables, which virtually mirrors the objects on one tabletop to the other. Tom takes “Monopoly” out of the cupboard and places the game board on the table, which thereby appears simultaneously on Sebastian's table. Conversely, the game pieces of Sebastian's family now also appear as a projection on Tom's game board. A tablet placed on the side hooks into the system and also offers the possibility of talking directly via video stream. This allows the two families to enjoy a relaxed game evening without having to organize a babysitter at short notice.

After all the children have gone to bed, Tom and his wife sit together over a glass of wine. The SmartProjectorLamp™ bathes the table in a warm, dim light. Tom practices a few songs on his guitar. The songbook lying on the table is selectively lit brighter, and the chords to be played are highlighted in color.

At 11 p.m., Tom falls wearily into bed, reviewing the day. There was a lot going on today, but somehow everything was much more relaxed and fulfilling than usual. He thinks only briefly about the new SmartProjectorLamp™, because it never pushed itself to the fore, but was always there when he needed it.

Project: Prototype deployment in the gastronomy room of the Degginger

Imagine you go out to eat and an “intelligent” table shows you the menu and informs you about the origin of the products. Or lets you bridge the waiting time for your meal with a little game. Soon, a VIGITIA prototype will turn these and other ideas into reality in the event and gastronomy room.
