Group play appears to have a positive effect on the physical and mental development of children. However, it is unclear what the effective elements of a group play intervention are. With colleagues from the Wilhelmina Children’s Hospital in Utrecht, we set out to thoroughly evaluate their “This is Me” sports- and play-based cognitive behavior therapy program. Major challenge was to systematically measure those aspects that measure play and wellbeing. The preprint of our article in Clinical Child Psychology and Psychiatry is now online. We are looking forward to hear from other groups that focus on measuring the process of group-based play therapy.
I’ve been accepted to the editorial board of IEEE Transactions on Affective Computing (TAC). Looking forward to receiving all your manuscripts!
The number of car incidents is rising again, after years of steady decline. One explanation is car drivers’ use of phones. The Dutch police is now introducing automated ticketing for drivers holding a phone, based on camera footage. The pilot for this technique has been developed in 2018 by my MSc student Jannes Elings. The Dutch police has continued to develop the technique, which is now ready for deployment on the public roads.
Georgios Kapidis will present his recent work on Multi-Task Learning for the recognition of actions in ego-centric videos at the EPIC workshop of ICCV. By predicting multiple outputs such as gaze targets and hand locations, we can improve the network structure which benefits other tasks such as action recognition. We demonstrate state-of-the-art results on the EGTEA Gaze+ dataset, and show nice improvements over only action recognition on EPIC Kitchens.
Alex Stergiou had a good run: three papers were accepted recently at ICIP (paper), ICMLA (paper) and the ICCV workshop on Interpreting and Explaining Visual Artificial Intelligence Models (paper). The papers deal with the visualization of what 3D CNNs learn for video recognition. Congrats on the acceptance!
From 1,997 entries, our documentary “A week without lying: The honesty experiment” has been selected as one of the 17 films at the APA Film Festival. It will be screened on Friday August 9. Should you be at the annual APA conference, make sure to watch it! Congratulations to Vicky Cooper and the team from Thoroughly Modern Media!
The Washington Post featured an article about USA President Trump’s 10,000st false or misleading claim. In the article, our paper “A personal model of trumpery: Deception detection in a real-world high-stakes setting” (by Sophie van der Zee, me, Alice Havrileck and Aurelien Baillon) has been mentioned. It describes our research on deception detection from President Trump’s tweets. Our research has greatly benefited from the Washington Post’s fact-checking endeavors.
From Saterday April 20 to Sunday May 5, a team of researchers from the University of Utrecht (led by Albert Ali Salah and me), Erasmus University Rotterdam (led by Sophie van der Zee) and University of Amsterdam (led by Theo Gevers) have conducted a citizen’s science project at the NEMO science museum in Amsterdam. In total 309 people from 6 years old have kindly lied to us in front the camera. Another 163 have provided their services as lie detectors. A huge success, stay tuned for the first results! Thanks to all participants, NEMO and the team.
Our (Sophie van der Zee, Ronald Poppe, Paul J. Taylor and Ross J. Anderson) paper “To freeze or not to freeze: A culture-sensitive motion capture approach to detecting deceit” was accepted for PlosOne. It describes our ground-breaking research on using motion capture technology to accurately, objectively and automatically detect whether people are lying. Our approach can distinguish between lies and truthful statements approximately 82% of the cases.
Our paper on tracking players to estimate their exertion has been published in IJHCS. This is work by Alejandro Moreno, together with Dirk Heylen and Jenny L. Gibson. We demonstrate that unobtrusive tracking, in the context of interactive play, can be readily used as a group measure for exertion. This shows promise for real-time adaptation of game mechanics, to keep exertion within a desirable range.
