Children with cancer feel often lonely when they are in hospital. In order to cheer them up, nine students in
the Interactive Environments minor designed the interactive light installation Seina, which can be used to make light tracks on the floor. The lamps in Seina use sensors to react to movement. Young patients can make their own light tracks, but they can also see where nurses, friends and family members have walked. This makes them feel less alone, both literally and figuratively, because the light tracks remain visible everywhere. Seina is being installed in the Princess Máxima Institute for Paediatric Oncology, which is scheduled to open in 2016.
