NUBSL A Freely Placeable, Low-cost Notification Utility

Abstract

We propose a tangible notification utility for remote maintenance of flats or houses in the context of Internet of Things , focusing on two core aspects: First, an alert feature in case of urgent problems which immediately informs the user about threats, damages or events with high priority, utilizing sound and light to ensure immediate response. Additionally, passive reminder functionality was implemented, which is related to tasks or events with low priority, in order to inform the user without distracting him from his current objectives. The novelty of the approach is the versatility of the devices, their mobility and the ability to place them anywhere in proximity to the user.
