We laten steeds meer sporen na: door op internet te surfen, door onze mobiele telefoon te gebruiken, door RFID-labels bij ons te dragen of door ons binnen het blikveld van camera’s te bewegen. Door de contextuele informatie die dit genereert te gebruiken als aanvulling op de ‘klassieke’ methode van gezichtsherkenning kunnen we de identificatie van personen sterk verbeteren. Bob Hulsebosch en Wouter Teeuw van het Telematica-instituut leggen uit hoe. Identificatie is het herkennen van een specifiek persoon – van wie de identiteit bekend is – in de menigte. Gezichtsherkenning speelt hierbij een grote rol. Uit camerabeelden leiden we een aantal gelaatskenmerken af, die we vergelijken met profielen in een database. Een match is mede afhankelijk van de tolerantie die we instellen. Bij een strenge instelling, met weinig ruimte voor onnauwkeurigheid, is de kans klein dat iemand ten onrechte wordt herkend (een lage false acceptance rate, of FAR), maar wordt de kans groter dat iemand uit de database ten onrechte niet wordt herkend (hogere false rejection rate, of FRR).

The capacity on the Northern ring road in Breda is approaching its limits. Due to planned spatial developments the ring road might even be under further pressure. Therefore the municipality of Breda is working on an action plan to deal with this task. This requires insight into the functioning of the Northern ring road, which has been achieved by combining the following data sources: • Meetweken Breda 1st edition (GPS)• Meetweken Breda 2nd edition (GPS)• OViN• License plate cameras (NRW)• Counting data (NRW)• Bluetooth data (NRW)• Weather data (KNMI)The results show that in comparison with other strongly urbanized cities, Breda is more oriented towards the car and less use is made of public transport and the bicycle. Particularly on short distances there is still potential to further increase bicycle usage. In depth results can be found in the presentation, including information about: peak hours, the number of trips per person per day, the percentage of multimodal trips and the effect of rain on route choice. By combining the insights from the different forms of data, additional insights and an overarching mobility picture emerge. In other words, the overall picture is more than the sum of the parts.
In the small village of Nuenen in the Netherlands, Vincent van Gogh, the legendary artist, resided with his parents for two years in the late 19th century. Today, visitors can literally walk in Vincent’s footsteps and hear stories about that period of his life. There is also a renovated indoor museum in the village showcasing many beautiful and inspiring objects.We carefully studied the visitor experience over two rounds of data collection: one in 2018 and another in 2023 after the museum's renovation. In the second round, 40 students from Breda University of Applied Sciences were invited to spend a day in Nuenen. The participants, aged mostly between 20 and 30 years, came from the Netherlands and 16 other countries. None of them had visited the previous museum setup in Nuenen, although two-thirds had visited at least one other Vincent-centered attraction or had researched Vincent and his life prior to the visit.During their visit, research participants were tracked using Bluetooth beacons (indoors) and GPS tracking (outdoors), while wearing wristbands that measured their level of emotional engagement in real time. They toured the museum and the village and provided feedback on their experience through questionnaires administered before and after the visit.The results of the research showed that visitors were emotionally touched at certain stops of the tour more than others, enjoyed interacting with specific elements in the museum, and spent more time in particular areas of the museum. Most participants could vividly imagine themselves back in the days (narrative transportation), felt closer to Nuenen residents as a result of the visit, and generally found the visit to be quite meaningful. Learning and self-expansion were high, with some visitors even finding the visit transformative, leading to changes in attitude, behavior, and identities. We also found a strong correlation between these measures and the Net Promoter Score (NPS). Recommendations and emotion maps were presented to the museum as they continue to refine their visitor experiences.Research carried out for Van Gogh Village Museum Nunen.
