Researchers at the University Teknologi Petronas in Malaysia are developing the Smart Veins Locator, a wearable head-mounted display that allows nurses to see patients' veins by overlaying a map of the veins on top of their skin.
The Smart Veins Locator prototype integrates a camera and light source into a head-mounted display to capture an image of the patient's skin using near infrared light. An image of the veins is processed and projected onto a see-through display. The veins perceived by the nurse's eyes are accurately mapped and overlaid onto the real-world image of the patient's skin.
The Smart Veins locator uses different wavelengths of light and can optimize wavelength for skin color. The prototype has been tested on fair, light brown, dark brown and dark skin and works equally well with all four complexions.
