Help make sure no one lies on the floor waiting for help.

FallGuard is a student-led public benefit project that uses AI to detect falls and alert caregivers in seconds.

Devices are free for families in need. The core ideas and code are shared so others can protect their own loved ones too.

Why Early Fall Detection Matters

Behind every number is a real family, a real person, and a life that could be changed by a faster response.

1% fatal injury increase per minute delay

Every minute without help can be the difference between recovery and tragedy.

  • According to the World Health Organization (WHO), falls are the second leading cause of unintentional injury deaths worldwide.
  • WHO reports that an estimated 684,000 people die from falls each year, many of whom could have survived with faster help.
  • Older adults and people living alone are especially vulnerable — often with no one nearby to see or hear them fall.
  • Research shows that each 1-minute delay in EMS response time is associated with about a 1% increase in the odds of a fatal fall injury.

FallGuard was built so that when someone falls, their loved ones are notified right away — not hours later.

Our Mission and Principles

FallGuard is not just a device. It is a promise that safety and dignity should not depend on income, location, or age.

Student-led public benefit project

  • Created and maintained by a student who watched loved ones suffer after falls and wanted to prevent others from going through the same pain.
  • Focused on protecting seniors, people with disabilities, and families under stress – not on maximizing profit.
  • Free devices for families in need, supported by donations of time, money, and unused tech.

Openness, protection, and fair use

To keep this technology from being locked away or turned into an expensive, closed product, I am exploring patent protection while making a clear commitment:

  • The core ideas and code behind FallGuard are shared so families, caregivers, and researchers can build their own systems.
  • Free for personal and research use: anyone who wants to protect their loved ones or study fall detection can use the open resources without paying licensing fees.
  • Any patent protection is meant to prevent misuse and stop others from turning this into a high-cost, locked-in service.

Technology should lower barriers to safety, not raise them. FallGuard exists to keep that principle at the center.

Why I Started FallGuard

About five years ago, my grandmother fell in the kitchen. No one noticed until some time had passed, and although we called 911 right away and got her to the hospital, the delay left her with permanent brain damage.

Later, a friend’s grandfather, who lived alone in another state, fell at home. His family didn’t find out until the next day. That experience made me realize that falls among elderly people are a common and serious problem — and their families can’t always be there to help right away.

FallGuard began as my science project, but it quickly became something bigger: a way to honor my grandmother and stand with every family that is afraid of “what if no one is there when they fall.”

Messages from People Waiting for FallGuard

“I use a wheelchair and have cerebral palsy. When I get stuck out of my chair, no one always knows. Your device could let me keep living at home safely instead of moving to a care facility.”

“My husband has advanced Parkinson’s and still falls a lot even with a walker. He won’t keep wearable devices on. A system like yours that doesn’t need charging or remembering would be a huge relief.”

“My mom with dementia has fallen many times in one year, breaking bones and needing stitches. She can’t remember to wear a button or charge a watch. Getting an instant alert when she falls could change everything for us.”

“I’m a senior living alone. I want to pay for my own device and even donate one to someone who can’t afford it. I wish I could give more, but I hope this helps another family stay safe.”

“After spine surgery, I live with constant pain and limited mobility. A fall could be devastating. I’m searching for any technology that lets me stay independent without being terrified of falling.”

“My adult son has epilepsy. During a seizure he can’t push a button or call for help. Your system that can recognize a fall on its own could protect him when he’s home alone.”

“At night I take off my hearing devices and I’m completely deaf. My spouse falls often, especially on the way to the bathroom. A quiet alarm wouldn’t help me, but a vibration alert on my phone would let me know immediately.”

“I serve on the tech committee at a retirement community. We’d like to evaluate your device because so many residents worry about falling and not being found in time.”

“I use a wheelchair and have cerebral palsy. When I get stuck out of my chair, no one always knows. Your device could let me keep living at home safely instead of moving to a care facility.”

“My mom with dementia has fallen many times in one year, breaking bones and needing stitches. She can’t remember to wear a button or charge a watch. Getting an instant alert when she falls could change everything for us.”

What FallGuard Can Do

How Would You Like to Join This Mission?

Whether you need protection at home or want to help others, you are part of the reason FallGuard exists.

My Family Needs FallGuard

If you or someone you love is at high risk of falling, you can apply for a free FallGuard device or use a computer you already have.

  • Apply for a free physical device (for families in need)
  • Turn your existing computer into a FallGuard device
  • Use our open-source tools to build your own setup

I Want to Help Others

This is not a company. It is a student-led public benefit project. Your support goes directly into protecting more families.

  • Donate to help cover the cost of building and shipping devices
  • Donate unused computers or Raspberry Pi boards
  • Collaborate as a researcher, developer, or organization

Your Support Can Save a Life

Every day, nearly 2,000 people die from falls. With over 400 families on the waiting list, every extra device means one more home that is not left in silence.

A Lifeline for Families in Need

My mission is to provide FallGuard for free to every family who needs it. But as a student, I cannot afford the production costs on my own. Each device costs about $100 to build.

Approximate Cost per Device:
  • Raspberry Pi & Camera: $75
  • 3D Printed Case & Mount: $15
  • Cables & Power Supply: $10

Your contribution, whether through donating unused tech or a small monetary gift, will directly help assemble and deliver a FallGuard to someone anxiously waiting.

About the Creator

Kevin Tang, Inventor of FallGuard

Hi, I'm Kevin Tang, a student at Cedarlane Academy in Hacienda Heights, California. I like creating new ways to solve everyday problems with technology, especially when those problems affect people who are often overlooked.

Through my project FallGuard, I had the chance to participate in the 3M Young Scientist Challenge, where I was honored to be named "America’s Top Young Scientist." I'm thankful to 3M and Discovery Education for giving me this incredible opportunity to share my work. They encouraged me to see FallGuard not only as a school project, but as a long-term commitment to public good.

I'm still developing FallGuard so it can protect and care for more people. If you want to help expand this project's impact — by sharing your expertise, donating devices, or simply spreading the word to a family who might need it — I’d be excited to connect.
