Probing Experience: From Assessment of User Emotions and Behaviour to Development of Products (Philips Research Book Series)

Abstract: This book adheres to the vision that in the future compelling user experiences will be key differentiating benefits of products and services. Evaluating the user experience plays a central role, not only during the design process, but also during regular usage: for instance a video recorder that recommends TV programs that fit your current mood, a product that measures your current level of relaxation and produces advice on how to balance your life, or a module that alerts a factory operator when he is getting drowsy. Such systems are required to assess and interpret user experiences (almost) in real-time, and that is exactly what this book is about. How to achieve this? What are potential applications of psychophysiological measurements? Are real-time assessments based on monitoring of user behavior possible? If so, which elements are critical? Are behavioral aspects important? Which technology can be used? How important are intra-individual differences? What can we learn from products already on the market? The book gathers a group of invited authors from different backgrounds, such as technology, academy and business. This is a mosaic of their work, and that of Philips Research, in the assessment of user experience, covering the full range from academic research to commercial propositions.

Unobtrusive Sensing of Psychophysiological Parameters

Abstract: The quantification of the human perception of experiences can be achieved by the sensing of specific psychophysiological parameters. A growing interest develops for the daily life use of these quantification techniques by unobtrusive and unnoticeable data collection. Remote and non invasive sensing technologies are discussed for the sensing of the following psychophysiological parameters: heart rate variability, and muscle stress. A generic miniature platform for miniature wireless sensing applications is described as an important enabler for unobtrusive and unnoticeable sensing. The technology no longer seems to be a limiting factor for unobtrusive and unnoticeable sensing. Initially the sensors will be worn on the body, but ultimately implantable sensors will become widely accepted, allowing access to new parameters, such as hormone levels and body core temperature.

Computer program product, method and device for guiding the breathing

Abstract: Breathing guide for guiding the breathing of a user, provided with a heart beat sensor configured to convert a human or animal heart beat into heart beat signals, a storage arrangement configured to store an algorithm, a processing circuit configured to process heart beat signals and breathing guidance signals, a user interface configured to indicate a breathing guidance signal, and an algorithm configured to convert the heart beat signals into breathing guidance signals and to synchronize the breathing guidance signals with the processed heart rate signals for the purpose of guiding the user towards an improved heart coherence.

Method and system for enabling generation of a summary of a data stream

Abstract: A summary of a data stream, comprising a plurality of segments, is generated. A data stream, comprising a plurality of segments, is transmitted to a plurality of users (step 300). Ratings in respect of at least one of the plurality of segments of the data stream are collected from a plurality of users (step 306). This enables a summary of the data stream to be generated on the basis of the collected ratings (step 308).
