abstract = {Two aspects of the design and characterization of activity recognition systems are rarely elaborated in the literature. First, the influence of system performance with variability in sensor placement and orientation is often overlooked. This is important for the deployment of robust activity recognition systems. Second, the influence of labeling variability is also overlooked, especially w.r.t. label boundary jitter and labeling errors. This is important during the development of an activity recognition system as acquiring labels is costly. We argue that there is a need to explicitly address the consequences of such variability in publications, together with the mitigation strategies that are used. Elaborating on this is required to move the state of the art towards real-world applications, such as in industrial wearable assistance applications or pervasive healthcare.},

abstract = {Current hearing instruments (HI) only rely on auditory scene analysis to adapt to the situation of the user. It is for this reason that these systems are limited in the number and type of situations they can detect. We investigate how context information derived from eye and head movements can be used to resolve such situations. We focus on two example problems that are challenging for current HIs: To distinguish concentrated from interaction, and to detect whether a person is walking alone or walking while having a conversation. We collect an eleven participant (6 male, 5 female, age 24-59) dataset that covers different typical office activities. Using person-independent training and isolated recognition we achieve an average precision of 71.7% (recall: 70.1%) for recognising concentrated work and 57.2% precision (recall: 81.3%) for detecting walking while conversing.},
