Example scenario: Tom and the SmartProjectorLamp™

This scenario describes the vision of the research project VIGITIA from a users point of view. Technical details and interaction techniques will be evolved during the course of the project.

Tom is 34, has a wife and three children. He is a homemaker, hobby musician and active in several social projects and associations.

This morning did not go well. The eggs were forgotten on the stove, child 1 spilled hot chocolate over its exercise book, child 2 missed the school bus and the car keys were nowhere to be found. Tom tried to wrap a birthday present for a friend of child 3. Despite all helpful YouTube tutorials, the result was only a bulky lump.

Late morning, a package arrives. Inside: The long-desired SmartProjectorLamp™. It is simply screwed into a normal lamp socket above the table. The SmartProjectorLamp™ integrates a projector with daylight brightness and multiple cameras to sense what is happening on the table below. A small enclosed box, the battery powered SensingMobileController™ is stuck underneath the table surface. Tom wakes the devices with a short knock onto the table. They sync and calibrate on their own and after a few seconds, the SmartProjectorLamp™ projects an interactive tour through the features of the now interactive table onto the tabletop.

After completing the tour, Tom decides to be productive right away with his new table. He summons a projected ruler which helps him to cut the wrapping paper straight and in the correct size. The birthday present looks way better now.

The table supports him with cooking lunch by projecting timers. After Tom placed sweet potatoes onto the table, cooking directions were provided automatically.

Child 3 returns home. By starting a minigame where dirt monsters need to be wiped away, Tom motivates it to wipe the table clean. Next, another game shows the correct positions of plates and cutlery and measures the speed and accuracy of setting the table. Child 3 sets the table multiple times to beat the high score. Tom needs to intervene so that they can finally eat.

After lunch, it is time for homework. Child 1 has forgotten its physics exercise book at school and it's the day before an exam. The mother of a classmate has sent the scanned pages using WhatsApp. Tom places his smartphone onto the table. It is recognized instantaneously and its newest images are shown as thumbnails next to the smartphone. Tom drags relevant images to the center of the table. There, they group automatically into a stack. Child 1 can now go through the virtual exercise book. A scanned worksheet needs to be printed again. Tom displays the printer icon on the tabletop and drags the image onto it.

Child 2 triggers the projection of a world map, which helps him to do its geography homework. Child 3 is fascinated by it and places Lego figures on all countries where it wants to travel sometime.

Early in the evening, a few neighbors come over to discuss solutions for the ramshackle playground in the neighborhood. To support and moderate the discussion, one brought a “group mirror” app on its tablet. By projecting who spoke how long next to each person, everybody can see that Tom did most of the talking so far. Therefore, he decides to hold back to give everybody a chance to present their arguments. As soon as an agreement has been reached, the plan is set out in writing and a scan of the table is made and sent automatically to all those present.

After the neighbors left, Tom gets a call from Sebastian, a friend from their student days who also owns a SmartProjectorLamp™. They decide to play a board game together with their families: Therefor they both launch the telepresence mode on their tables. This mode mirrors objects of one tabletop to the other respectively. Tom gets “Monopoly” from the cupboard and places the game board onto the table which therefore also appears onto Sebastian's table. In reverse, the playing pieces of Sebastian's family also appear on Tom's game board. A tablet positioned vertically alongside the table is also integrated into the system and provides video calling functionalities. The system enables a relaxed games night for both families without the need to organize a babysitter at short notice.

After all children were put to bed, Tom and his wife let the day come to an end with a glass of wine. The SmartProjectorLamp™ illuminates the table with a warm, dim light. Tom practices a few songs with his guitar. The songbook on the table is more brightly lit than the surroundings and the current chords to be played are highlighted in color.

At 11 pm, Tom goes to bed and thinks back over the day. A lot has happened today, but somehow everything was much more relaxed and fulfilled than usual. He only things briefly about the new SmartProjectorLamp™ because it never pushed its way into the foreground, but was always there when it was needed.
