Abstract
This paper presents BioFidget, a biofeedback system that integrates physiological sensing and display into a smart fidget spinner for respiration training. We present a simple yet novel hardware design that transforms a fidget spinner into 1) a nonintrusive heart rate variability (HRV) sensor, 2) an electromechanical respiration sensor, and 3) an information display. The combination of these features enables users to engage in respiration training through designed tangible and embodied interactions, without requiring them to wear additional physiological sensors. The results of this empirical user study prove that the respiration training method reduces stress, and the proposed system meets the requirements of sensing validity and engagement with 32 participants in a practical setting.
Biofeedback clinic for functional abdominal painesowder
This document proposes establishing a biofeedback clinic at Children's Specialists of San Diego and UC San Diego to treat recurrent abdominal pain. Biofeedback is a non-invasive treatment that uses sensors and feedback to help patients learn to control the autonomic nervous system and reduce stress and pain. The clinic would be staffed by a biofeedback technician, psychologist supervisor, and intern. It would serve patients referred from GI physicians and generate revenue to cover costs and provide compensation. The goal is to effectively treat recurrent abdominal pain and potentially expand to other conditions and locations.

This document provides an overview of mind-body interventions such as meditation, guided imagery, and mindfulness techniques that can be used in therapeutic recreation practices. It discusses how these ancient spiritual practices are now being incorporated into Western medical models. Research studies have found that meditation changes brain regions and can help reduce stress, depression, pain, and support rehabilitation from sports injuries. Guided imagery, relaxation, and visualization techniques have also been shown to help reduce functional abdominal pain in children and support pre-surgery anxiety reduction and recovery. The implications are that these mind-body practices may provide valuable, evidence-based tools for therapeutic recreation professionals to improve client health and well-being.
1) Yoga practices such as pranayama, asanas, kriyas and relaxation techniques can help improve respiratory disorders by strengthening the lungs and relaxing the respiratory muscles.
2) Specific practices like neti kriya, anu nasika pranayama, and kunjal kriya help clear mucus and open the nasal passages and sinuses. Deep yogic breathing practices like pranava pranayama target different parts of the lungs.
3) Research shows that yoga is an effective adjunct therapy for respiratory conditions like COPD and asthma, improving symptoms, quality of life, and decreasing medication use. Yoga breathing safely increases oxygen levels and reduces stress on
Biofeedback is a technique that teaches people how to control involuntary bodily functions like breathing, muscle tension, and heart rate through the use of electronic or electromechanical devices that provide feedback on these physiological processes. It involves learning to control external signals and eventually internal cues to gain awareness and control over one's body. Biofeedback sessions with a trained professional typically involve sensors attached to the body to monitor functions and provide audio or visual feedback to help the individual learn control through relaxation techniques and practice. While not a cure, biofeedback has been shown to help treat various conditions involving muscle tension and stress and is gaining wider acceptance in mainstream healthcare.
1) The document summarizes presentations from the #HyperWellbeing summit 2016 about emerging technologies in wearables, sensors, machine learning and data analytics that aim to optimize health and wellbeing.
2) Many presenters discussed collecting clinical-grade biometric data from sensors and analyzing it using machine learning/AI to provide personalized insights and recommendations to consumers for preventative healthcare.
3) Other topics included continuous monitoring of metabolism, sleep, stress and cognitive/emotional states to close the loop between measurement and behavior change through just-in-time interventions.
This document discusses a presentation on using INDIGO biofeedback to help reduce stress. It begins with an introduction of the presenter and defines stress and the body's stress responses. It then outlines the INDIGO biofeedback system which measures the body's electrical signals to design personalized stress reduction programs. A typical session involves the client wearing sensors while different signature programs are used to help the body manage stressors. Multiple sessions over time are usually needed to retrain stress patterns as the system provides a drug-free holistic approach to stress reduction and overall health and wellness.

Biofeedback is a technique used in rehabilitation that provides patients with sensory information about their physiological functions and movements. This allows them to learn self-regulation of certain bodily processes. The summary discusses two main categories of biofeedback - physiological and biomechanical. Physiological biofeedback techniques discussed include EMG, HR, HRV, and respiratory biofeedback. Biomechanical techniques include use of force plates, inertial sensors, electrogoniometers, and camera systems to provide feedback on movement and balance. The summary concludes that while evidence supports use of biofeedback in rehabilitation, more research is still needed.
The document discusses a proposed brainwave entrainment app. It would use isochronic tones delivered through headphones or speakers to alter the user's brainwaves in order to change how they feel. Previous research found brainwave entrainment effective for issues like stress, headaches, and cognitive deficits. The app would include self-quantification measures like mood diaries, memory tests, and health metrics to track changes from using the app. A field study is proposed to evaluate the app's effectiveness on a sample of university students.

Advanced Techniques For Physiotherapy In 2020Fordly
May is observed as the national month of physiotherapy. In this month of physiotherapy, let us see how physiotherapy has grown and emerged with advanced treatment methods. The latest rehabilitation methods include rehab robotics, aquatic therapy, light therapy, and all to speed up recovery and provide more positive outcomes.
Brainwave entrainment refers to the brain's electrical response to rhythmic sensory stimulation like sound pulses. The premise is that certain technologies like isochronic tones can alter brain waves to change how one feels. Previous research found brainwave entrainment effective for issues like stress and cognitive deficits. The proposed app would use isochronic tones, unlike most apps that use binaural beats. It would also incorporate self-quantification measures like mood diaries and physiological tests to track changes from using the tones. Focus groups and interviews were conducted with students to design the app for reducing stress.
Biofeedback is gaining popularity in sports psychology for improving athletic performance and facilitating recovery from injury. Several studies show biofeedback reduces anxiety and stress, allowing optimal performance. It improves focus, concentration, and cognitive function following concussions. HRV biofeedback lowers anxiety and improves basketball and golf performance. Neurofeedback activates prefrontal areas associated with confidence. A baseball player increased self-confidence and performance using EEG biofeedback combined with imagery. Future research should establish guidelines and study long-term benefits to validate biofeedback's role in sports.

Yoga practices such as postures, breathing techniques, and meditation can benefit respiratory disorders in several ways. Slow yogic breathing maintains blood oxygenation without increasing ventilation and reduces sympathetic activation during hypoxia. Specific practices like kapalabhati and nadi shodhana pranayama improve lung function and respiratory muscle strength. Yoga techniques including neti kriya and chanting can help clear sinus passages and prevent infections. Research has found yoga therapy can significantly improve symptoms, lung function, and quality of life for patients with respiratory conditions like asthma and COPD when used as an adjunct to medical treatment.
The document discusses wellness and a tool called the Aarogya Tracking Module (ATM) that can help manage wellness. The ATM uses a German device called the BPR System to perform a 1-minute, non-invasive test of 43 organs. It then provides an interpretation and suggestions to help maintain health and balance in all life facets. The ATM aims to detect potential health issues early and aid preventive healthcare management.
- The document discusses developing technology to help manage stress and promote wellbeing in everyday, real-world ("in the wild") contexts through non-obtrusive sensing and subtle interventions.
- Current approaches to stress management are often not adopted due to barriers like needing to visit a clinic. The goal is to develop interventions integrated into everyday activities and environments.
- Examples discussed include detecting stress from driving behavior and providing guided breathing exercises in cars to help drivers relax. Other work aims to enhance driver arousal through fast-paced breathing interventions.
- The approach aims to break up the daily stress cycle by intervening during work, commutes, and evenings using ambient and integrated technologies designed not to disrupt normal activities.
The document summarizes a study that compared the effectiveness of different combinations of manual therapy and exercise for treating mechanical neck pain. All patients received neck exercises and cervical spine mobilization. Additionally, some patients received thoracic spine manipulation. Those who received all three treatments experienced greater reductions in neck pain and improvements in daily functioning after one week compared to those who only received exercises and cervical mobilization. The combination of neck exercises, cervical mobilization, and thoracic manipulation led to quicker relief of neck pain symptoms.
The document discusses plans for a final project to develop assistive technologies for stroke rehabilitation. It aims to explore how technologies can augment the lives of stroke victims and help them regain independence through physical and occupational therapy exercises in the home. The document provides examples of similar projects using virtual reality and gaming technologies for arm and wrist rehabilitation. It outlines future plans to conduct user research, develop prototype solutions, and test them through an iterative process with therapists.

Virtual reality and healthcare - the past, the present, and the futureStanford University
This presentation provides an overview of how VR and AR technology will impact medicine, clinical care, and personal health and wellness, and how it will help to facilitate the shift of medicine to direct personal care.
Although entertainment, social connection, and gaming will drive the initial adoption of Virtual Reality and Augmented Reality technology, the deepest and most significant impact of the next generation of VR/AR technology will be to enhance clinical care and to improve personal health and wellness.
We know from decades of clinical research that VR/AR technology can provide breakthrough solutions that address the most difficult problems in healthcare - ranging from mood disorders such as Anxiety and Depression to PTSD, Addictions, Autism, Cognitive Aging, Stroke Recovery and Physical Rehabilitation, to name just a few.
VR/ AR technology also improved clinical measurements and assessments, can greatly improve medical training such as surgical skill training and procedure planning. Personal health and wellness will be improved by using VR to promote healthy lifestyles and to reduce stress and anxiety. As the cost of healthcare rises, VR/AR technology can serve as an effective telemedicine platform to reduce costs of care delivery, and improve clinical efficiency.

We present GaussRFID, a hybrid RFID and magnetic-field tag sensing system that supports interactivity when embedded in retrofitted or new physical objects. The system consists of two major components — GaussTag, a magnetic-RFID tag that is combined with a magnetic unit and an RFID tag, and GaussStage, which is a tag reader that is combined with an analog Hall-sensor grid and an RFID reader. A GaussStage recognizes the ID, 3D position, and partial 3D orientation of a GaussTag near the sensing platform, and provides simple in- terfaces for involving physical constraints, displays and actu- ators in tangible interaction designs. The results of a two-day toy-hacking workshop reveal that all six groups of 31 par- ticipants successfully modified physical toys to interact with computers using the GaussRFID system.

GaussStones: Shielded Magnetic Tangibles for Multi-Token Interactions on Portable Displays
This work presents GaussStones, a system of shielded magnetic tangibles design for supporting multi-token interactions on portable displays. Unlike prior works in sensing magnetic tangibles on portable displays, the proposed tangible design applies magnetic shielding by using an inexpensive galvanized steel case, which eliminates interference between magnetic tangibles. An analog Hall-sensor grid can recognize the identity of each shielded magnetic unit since each unit generates a magnetic field with a specific intensity distribution and/or polarization. Combining multiple units as a knob further allows for resolving additional identities and their orientations. Enabling these features improves support for applications involving multiple tokens. Thus, using prevalent portable displays provides generic platforms for tangible interaction design.

This work describes a novel building block system for tangible interaction design, GaussBricks, which enables real-time constructive tangible interactions on portable displays. Given its simplicity, the mechanical design of the magnetic building blocks facilitates the construction of configurable forms. The form constructed by the magnetic building blocks, which are connected by the magnetic joints, allows users to stably manipulate with various elastic force feedback mechanisms. With an analog Hall-sensor grid mounted to its back, a portable display determines the geometrical configuration and detects various user interactions in real time. This work also introduce several methods to enable shape changing, multi-touch input, and display capabilities in the construction. The proposed building block system enriches how individuals interact with the portable displays physically.

We present GaussBits, which is a system of the passive magnetic tangible designs that enables 3D tangible interactions in the near-surface space of portable displays. When a thin magnetic sensor grid is attached to the back of the display, the 3D position and partial 3D orientation of the GaussBits can be resolved by the proposed bi-polar magnetic field tracking technique. This portable platform can therefore enrich tangible interactions by extending the design space to the near-surface space. Since non-ferrous materials, such as the user's hand, do not occlude the magnetic field, interaction designers can freely incorporate a magnetic unit into an appropriately shaped non-ferrous object to exploit the metaphors of the real-world tasks, and users can freely manipulate the GaussBits by hands or using other non-ferrous tools without causing interference. The presented example applications and the collected feedback from an explorative workshop revealed that this new approach is widely applicable.

[OReilly Superstream] Occupy the Space: A grassroots guide to engineering (an...Jason Yip
The typical problem in product engineering is not bad strategy, so much as “no strategy”. This leads to confusion, lack of motivation, and incoherent action. The next time you look for a strategy and find an empty space, instead of waiting for it to be filled, I will show you how to fill it in yourself. If you’re wrong, it forces a correction. If you’re right, it helps create focus. I’ll share how I’ve approached this in the past, both what works and lessons for what didn’t work so well.
Have you ever been confused by the myriad of choices offered by AWS for hosting a website or an API?
Lambda, Elastic Beanstalk, Lightsail, Amplify, S3 (and more!) can each host websites + APIs. But which one should we choose?
Which one is cheapest? Which one is fastest? Which one will scale to meet our needs?
Join me in this session as we dive into each AWS hosting service to determine which one is best for your scenario and explain why!

Bram Verhoef, Head of Machine Learning at Axelera AI, presents the “How Axelera AI Uses Digital Compute-in-memory to Deliver Fast and Energy-efficient Computer Vision” tutorial at the May 2024 Embedded Vision Summit.
As artificial intelligence inference transitions from cloud environments to edge locations, computer vision applications achieve heightened responsiveness, reliability and privacy. This migration, however, introduces the challenge of operating within the stringent confines of resource constraints typical at the edge, including small form factors, low energy budgets and diminished memory and computational capacities. Axelera AI addresses these challenges through an innovative approach of performing digital computations within memory itself. This technique facilitates the realization of high-performance, energy-efficient and cost-effective computer vision capabilities at the thin and thick edge, extending the frontier of what is achievable with current technologies.
In this presentation, Verhoef unveils his company’s pioneering chip technology and demonstrates its capacity to deliver exceptional frames-per-second performance across a range of standard computer vision networks typical of applications in security, surveillance and the industrial sector. This shows that advanced computer vision can be accessible and efficient, even at the very edge of our technological ecosystem.

Hi, this is Rong-Hao. We are from
TU Eindhoven Industrial Design.
I would like to share an interesting
project with you.
It’s called BioFidget:
Biofeedback for respiration training
using an augmented fidget spinner.
4. When we’re confronted with challenges in our everyday life, we feel stressed.
Stress can be a good thing that improves our performances.
But, a long-term stress can lead serious health problem.
Therefore, we need to manage stress.

RespirationTraining
is Clinical-Proven in Stress Reduction,
In respiration training, what you need
to do is to take slow and steady deep
breathing in 6 cycles per minute. After
3-5 minute, it will relax your central
nerve system and you will feel much
more relieved.
Well, what’s the problem then?

RespirationTraining

but People Usually Drops Out.
The problem is, people usually drops
out this process.
Honestly, it’s a boring boring exercise.
It’s neither competitive nor rewarding.
So, when there is a distraction,
people just let go.
8. Stretch Sensor for Breath Sensing
ImprovingEngagement
Respiration Training with Biofeedback
To engage people in respiration training, we can provide biofeedback.
Biofeedback is a therapy that has been applied for a long time.
The therapist just put a screen in front of the patient.
9. Stretch Sensor for Breath Sensing
Respiration
Heart Rate Variability (HRV)
(The variation in the Inter-beat Interval)
The screen shows two curves.
The blue curve is the respiration level.
The violet curve is heart-rate variability, HRV,
which is the variation in the inter-beat intervals.
10. Stretch Sensor for Breath Sensing
Respiration
Heart Rate Variability (HRV)
(The variation in the Inter-beat Interval)
A proper respiration training may synchronize
these two curves, because the deep breathing
regulates the heart rate.
11. Stretch Sensor for Breath Sensing

Respiration Training with Biofeedback
of Respiration and Heart Rate Variability (HRV) Information
During the respiration training, the patient tries to control their
breathing to match the respiration curve to the HRV curve.

19. FidgetSpinner
One thing we do when we’re stressed is fidgeting.
Last year, Fidget Spinners went viral.
In the spinning, the visual and tactile feedback are very soothing even addictive.
It’s healing, that’s why people love it. Nonetheless, it has no biosensors, so it
does not provide biofeedback based on the biosignals.
20. FidgetSpinner
… “fidget spinners and other self-regulatory
occupational therapy toys have yet to be subjected to
rigorous scientific research. Thus, their alleged
benefits remain scientifically unfounded.”
Schecter, Rachel A., et al.
"Fidget spinners: Purported benefits, adverse effects and accepted alternatives."
Current opinion in pediatrics 29.5 (2017): 616-618.
Importantly, regarding stress management, the clinical
effects of a spinner is still scientifically baseless.

user interfaces as fidgets to help the users in doing

Therefore, a fidget spinner can provide the

QuantitativeResults
2. The Clip Stabilized the HRV Sensing
and Enabled Blowing Input
PPG sensor #2
(baseline)
In the Blow session, the HRV collected by
BioFidget with a clip is even similarly reliable
to the one collected by the Baseline PPG,
showing that the blowing action does not
affect the validity of HRV collection.
70. Flicking
Detected
QuantitativeResults
Strategy of HRV data collection
The results suggest an HRV data collection strategy. When a
flicking is detected, we temporary ignore the rest of the HRV
data, until 3 consecutive heartbeats have been detected.
77. Fan-ShapedWing
To increase the sensitivity to respiration
The fan-shaped wing increases the sensitivity to the respiration.
78. Fan-ShapedWing
To increase the sensitivity to respiration
It enables the users to easier blow on the wing and get sensed
without moving the spinner towards the mouth.
79. Fan-ShapedWing
Allows for static use
The wing also enables the use on the table or a display, so the HRV
sensing would be stable even without a clip, as shown in pilot study.

The display can provide more insightful information, such as the history of respiration training.
For instance, the differences between an adequate and an inadequate trainings can be
observed from the resulting drawings, because the respiration regulates the heart rate.

• Tethershouldberemovedandreplacedbyabattery.
• Optimizingthepowerconsumptionisnecessary.
• ImprovingHRVsensingusingmotion-resilientECGsensor.
• MakingVisualizationmoreInformative
• Amoresophisticatedincentivemechanismforlong-termuses.
There are still some limitations in our physical design, such as the tether,
power and sensor choices. Also, the visualization and the incentive
mechanism could be improved. We leave them as future work.
