Abstract To design a more robust artifact, an artifact based on rationale analysis is pivotal. Errors in previous rationales that led to the degradation of robustness past provide valuable knowledge towards improving design. However, methods for exposing and analysing errors remain unclear. This paper proposes structured method logical structuring. provides well-constructed means identifying fr...

Artifact rejection is a central issue when dealing with electroencephalogram recordings. Although independent component analysis (ICA) separates data in linearly independent components (IC), the classification of these components as artifact or EEG signal still requires visual inspection by experts. In this paper, we achieve automated artifact elimination using linear discriminant analysis (LDA...

Computing today happens across multiple devices, applications, users, organizational units, and in the rest of world outside. Groups communities come together for different reasons operate within contexts that may differ from dominant modes production consumption. With a foundation activity theoretical HCI, we develop concept collective artifact ecologies. This enables us to identify struggles ...
