“…For our study, we decided to use HRV as a quantitative stress indicator, based on previous research documenting the relaxing effects of slow paced respiration exercises [4,22] and biofeedback applications [8,20,29] relying on HRV as a stress indicator as well.…”

Breathing exercises can help children with ADHD control their stress level, but it can be hard for a child to sustain attention throughout such an exercise. In this paper, we present ChillFish, a breath-controlled biofeedback game designed in collaboration with ADHD professionals to investigate the possibilities of combining breathing exercises and game design. Based on a pilot study with 16 adults, we found that playing ChillFish had a positive effect, helping the participants to reach a relaxed state similar to the one offered by traditional breathing exercises. Further, we analyze the opportunities and challenges of creating a tangible respiration-based controller and use it as a core game mechanic. Finally, we discuss the challenge of balancing engagement and relaxation in physically controlled games for children with ADHD in order to make a game that can be calming and still sustain their attention.

“…Consistent with the literature, the comparison between music and non-music conditions also shows the beneficial effect of sedative music in lowering arousal activities (SCRs and HR). On the other hand, UnWind suggests a new approach to design musical biofeedback, which does not deal with complex musical structures (Yokoyama et al 2002;Bergstrom, Seinfeld, and Arroyo-Palacios 2014) or modify the sound effects (Harris et al 2014;Bhandari et al 2015), but can also harness the benefits of sedative music. To the best of our knowledge, this is the first musical biofeedback interface that combines nature sounds with sedative music for both presenting biofeedback data and also promoting relaxation.…”

“…Different from other musical biofeedback displays (e.g. Yokoyama et al 2002;Bergstrom, Seinfeld, and Arroyo-Palacios 2014;Harris et al 2014;Bhandari et al 2015), this combination enables UnWind to be informative for biofeedback, but also sound like a piece of well-composed music. In the experiment, we examined the possible effects arising from this combination, and investigated the effectiveness of UnWind for relaxation assistance, regarding optimising the breathing pattern, enhancing HRV, moderating arousal level, and reducing subjective anxiety.…”

“…In the other category, the interfaces modify the sound effects of a pre-selected musical piece for biofeedback display. For instance, Harris et al (2014) developed a musical biofeedback system that encourages slow breathing by adjusting the quality of a music recording in proportion to the user's respiration rate. Similarly, Bhandari et al (2015) developed a respiratory biofeedback system which presents the user's breathing signal by modifying the intensity of the white noise that blends into a piece of music.…”

Unwind is a musical biofeedback interface which combines nature sounds and sedative music into a form of New-Age music for relaxation exercises. The nature sounds respond to the user's physiological data, functioning as an informative layer for biofeedback display. The sedative music aims to induce calmness and evoke positive emotions. UnWind incorporates the benefits of biofeedback and sedative music to facilitate deep breathing, moderate arousal, and promote mental relaxation. We evaluated Unwind in a 2 × 2 factorial experiment with music and biofeedback as independent factors. Forty young adults performed the relaxation exercise under one of the following conditions after experiencing a stressful task: Nature sounds only (NS), Nature sounds with music (NM), and Auditory biofeedback with nature sounds (NSBFB), and UnWind musical biofeedback (NMBFB). The results revealed a significant interaction effect between music and biofeedback on the improvement of heart rate variability. The combination of music and nature sounds also showed benefits in lowering arousal and reducing self-report anxiety. We conclude with a discussion of UnWind for biofeedback and the wider potential of blending nature sounds with music as a musical interface. ARTICLE HISTORY

“…With diaphragmatic breathing, sensors located on the abdomen (e.g., strain gauges, accelerometers, linear potentiometers) pick up respiration-induced abdominal movements, which are then used to infer respiration. The detected signals (inhalation, exhalation) can be fed back to the user directly (e.g., Tinga et al 2019;van Rooij et al 2016;Vidyarthi and Riecke 2013) or in the form of pre-processed, aggregated parameters such as respiratory frequency or depth (e.g., Bhandari et al 2015;Harris et al 2014;Morarend et al 2011;Parnandi et al 2013). The feedback can serve several goals.…”

Breathing exercises with biofeedback have benefits over breathing exercises without biofeedback. However, the traditional measurement of respiratory signals that is required as part of feeding back the breath incurs high cost and effort. We propose a novel virtual reality (VR) based approach to respiratory biofeedback that utilizes the positionally tracked hand controllers integrated into modern VR systems to capture and feedback the respiration-induced abdominal movements. In a randomized controlled laboratory study, we investigated the feasibility and efficacy of the developed biofeedback algorithm. In total, 72 participants performed a short breathing exercise in VR with or without respiratory biofeedback. The feedback integration resulted in a satisfactory user experience, a heightened breath awareness, a greater focus on slow diaphragmatic breathing and an increased respiratory sinus arrhythmia. This evidences that the novel biofeedback approach is low-cost, unobtrusive, usable and effective in increasing breath awareness and promoting slow diaphragmatic breathing in the context of VR-based breathing exercises. Future studies need to investigate the broader applicability and long-term effects.
