MeditAid:a wearable adaptive neurofeedback-based system for training mindfulness state

A recent interest in interaction design is towards the development of novel technologies emphasizing the value of mindfulness, monitoring, awareness, and self-regulation for both health and wellbeing. Whereas existing systems have focused mostly on relaxation and awareness of feelings, there has been little exploration on tools supporting the self-regulation of attention during mindfulness sitting meditation. This paper describes the design and initial evaluation of MeditAid, a wearable system integrating electroencephalography (EEG) technology with an adaptive aural entrainment for real time training of mindfulness state. The system identifies different meditative states and provides feedback to support users in deepening their meditation. We report on a study with 16 meditators about the perceived strengths and limitations of the MeditAid system. We demonstrate the benefits of binaural feedback in deepening meditative states, particularly for novice meditators

Audio-tactile stimuli to improve health and well-being : a preliminary position paper

From literature and through common experience it is known that stimulation of the tactile (touch) sense or auditory (hearing) sense can be used to improve people's health and well-being. For example, to make people relax, feel better, sleep better or feel comforted. In this position paper we propose the concept of combined auditory-tactile stimulation and argue that it potentially has positive effects on human health and well-being through influencing a user's body and mental state. Such effects have, to date, not yet been fully explored in scientific research. The current relevant state of the art is briefly addressed and its limitations are indicated. Based on this, a vision is presented of how auditory-tactile stimulation could be used in healthcare and various other application domains. Three interesting research challenges in this field are identified: 1) identifying relevant mechanisms of human perception of combined auditory-tactile stimuli; 2) finding methods for automatic conversions between audio and tactile content; 3) using measurement and analysis of human bio-signals and behavior to adapt the stimulation in an optimal way to the user. Ideas and possible routes to address these challenges are presented

Multi-point STM: Effects of Drawing Speed and Number of Focal Points on Users’ Responses using Ultrasonic Mid-Air Haptics

Spatiotemporal modulation (STM) is used to render tactile patterns with ultrasound arrays. Previous research only explored the effects of single-point STM parameters, such as drawing speed (Vd). Here we explore the effects of multi-point STM on both perceptual (intensity) and emotional (valence/arousal) responses. This introduces a new control parameter for STM - the number of focal points (Nfp) – on top of conventional STM parameter (Vd). Our results from a study with 30 participants showed a negative effect of Nfp on perceived intensity and arousal, but no significant effects on valence. We also found the effects of Vd still aligned with prior results for single-point, even when different Nfp were used, suggesting that effects observed from single-point also apply to multi-point STM. We finally derive recommendations, such as using single-point STM to produce stimuli with higher intensity and/or arousal, or using multi-point STM for milder and more relaxing (less arousing) experience

Healing through sound: An exploration of a vocal sound healing method in Great Britain

This thesis reports the results of ethnographic research conducted on a vocal sound healing method practiced in Great Britain at the College of Sound Healing, founded by acupuncturist and sound healer Simon Heather. This phenomenological, narrative inquiry embraces a perspective recognizing the dialogic nature of ethnographic research, and includes the perspective of sensory anthropology by exploring the role of the senses in sound healing. The research also positions sound healing in relation to the field of music therapy, the career practiced by the researcher. The study involved a sample of 13 individuals who had undergone sound healing. Data collection consisted of interviews and participant observation/sensation. Findings of the study reflect a wide range of experiences which embrace a holistic conception of health encompassing both mind and body. Categories evolving out of participants’ own language used to describe their experiences include the following: physical, mental, insight, emotional and spiritual. Effects such as the release of emotions and trauma, a change from negative to more positive thought patterns, the elimination of physical pain, relaxing, calming effects and receiving deeper perceptions of life situations, are among the experiences described by participants. Contributions to an evolving theory of sound healing include the recognition that altered states of consciousness appear to play an important role in facilitating certain kinds of healing; the phenomenon of after-effects of sound healing which extend and evolve for sometimes days, weeks and even months after a sound healing session; the role of the senses in terms of healing efficacy, with colors experienced as healing in and of themselves; and an analysis of the relationship between intuition, intention and the sounds utilized in this method of sound healing
