# Problem
Due to their busy work schedules, many families are faced with the inevitable situation of leaving the elderly alone at home. This makes it a challenge to respond to emergencies of elderly falls at home and to monitor the health of the elderly. There is a need for a way to remotely know the activities and health status of the elderly at home.

# Solution Overview
Our solution for above problem is that use Wi-Fi devices that could send Wi-Fi signals for motion detection while ensuring data privacy and make wearable devices with multiple sensors attached to assist Wi-Fi monitoring. We will build an integrated monitoring system combining Wi-Fi monitoring devices and wearable sensors used for emergency happening in old people’s home.

# Solution Components

## Detection Subsystem
- Wi-Fi devices sending Wi-Fi signal providing most data
- Wearable devices with sensors providing data for assistence

## Processing and Output Subsystem
- Algorithm that identify present situation
- User Interface that send alarm to remote device.

# Criterion for Success
- Common Wi-Fi devices that can be used to obtain the desired Wi-Fi signal
- Wearable devices that are convenient and less likely to leak private information
- Algorithms that quickly and accurately determine the current situation
- Simple and easy-to-use user interfaces and alerts.

Bone Conduction Lock

Featured Project

A lock that is unlocked using vibrations conducted through the bones in the user’s hand. The user wears a wristband containing a haptic motor. The haptic motor generates a vibration signal that acts as the "key" to the lock. When the user touches their finger to the lock, the signal is transmitted through the user’s hand and is received at the lock. If the lock receives the correct "key", then it unlocks.
