This qualitative study explored the childhood experiences of growing up with a sibling with Developmental Coordination Disorder (DCD) to offer an 'outsider's' view of this condition. Ten individuals who had grown up with a sibling with DCD were interviewed about their experiences. Data were analysed using Thematic Analysis. Analysis described three main themes: i)'witnessing the challenges for their sibling with DCD' ii) 'experiencing the impact on the family'; iii) 'a vacuum of knowledge'. Not all experiences were negative and transcending these themes was the notion 'resolution and finding benefit' highlighting access to support, being more empathic and resilient, becoming a role model for others and finding success. Participants play witness to their sibling's experiences which can often be negative sometimes impacted by a vacuum of knowledge but they also describe how a diagnosis of DCD comes with some benefits which are discussed in the context of 'posttraumatic growth'., Author(s): Brendan Morris [sup.1] , Jane Ogden [sup.1] , Judith Gentle [sup.1] Author Affiliations: (1) grid.5475.3, 0000 0004 0407 4824, School of Psychology, University of Surrey, , Guildford, GU2 7XH, [...]

This paper presents a survey of trajectory-based activity analysis for visual surveillance. It describes techniques that use trajectory data to define a general set of activities that are applicable to a wide range of scenes and environments. Events of interest are detected by building a generic topographical scene description from underlying motion structure as observed over time. The scene topology is automatically learned and is distinguished by points of interest and motion characterized by activity paths. The methods we review are intended for real-time surveillance through definition of a diverse set of events for further analysis triggering, including virtual fencing, speed profiling, behavior classification, anomaly detection, and object interaction. Index Terms--Event detection, motion analysis, situational awareness, statistical learning.
