Wearable Technology in Healthcare

Wearable tech for the visually impaired

Researchers have created a wearable computer to aid the blind, and help reduce collision risk.
The computer consists of a small mainboard and several cameras which allow it to detect objects around the wearer, when used in conjunction with a guide dog, it is reportedly 40% effective at preventing collisions (source)
This device can also be beneficial to those who cannot afford the expense of a guide dog, which can cost up to $60,000 Upon detection of a collision hazard, one of the two bluetooth enabled wristbands that the user wears will vibrate, indicating which direction the object is in

Wearable tech for health monitoring

Many people now own a smart watch, the capabilities of which are ever expanding. Most modern smart watches have the capability to track heart rate, and some have more advanced features, such as SpO2 monitoring
Even outside of professional healthcare scenarios, this functionality can encourage users to lead a more healthy lifestyle.
The primary concerns of the use of consumer wearables in a professional setting are the high risk of false positives being thrown due to improper use, and the fact that a user must actively engage for the device to be effective.
Providing a statement of "you have high blood pressure" is of little benefit if the user will not adapt their lifestyle to ammend it.
