Be-In/Be-Out (BIBO) is considered a simple paradigm for hands-free interaction in the domain of multimodal public transport systems where travellers automatically obtain their tickets by entering and leaving means of transportation. The infrastructure in the vehicles detects the passengers’ presence and initiates services unnoticed in the background. Whereas first implementations of BIBO systems are based on active Radio Frequency Identification (RFID), where users carry small RFID-tags in their pockets, we focus on Bluetooth Low Energy (BLE) as an alternative but potentially more powerful technology for this domain. We try to carve out differences, accentuate arising opportunities for interaction and evidence the applicability of BLE for BIBO systems by a series of conducted screening tests.
