Interaction design of automatic faucet for standard hand-wash

Abstract

Abstract. In hand-washing practice, people tend to forget to use soap and scrub for 20 seconds as stated in the standard. This paper attempts to develop an automatic faucet that is user-friendly and easy to plug in regular water pipe for standard hand-washing routine. An Interaction Design Process that aims to maximize product usability was applied during the development. The faucet utilized IR proximity sensor to detect presence of hands that would automatically commence the hand-washing process. First, it exited water and soap simultaneously to force users to use soap. The scrubbing duration was marked by buzzer's sound and LED's light. The validation test showed health practitioner agreed the faucet facilitates a standard handwashing. The user test in 30 participants showed users used soap and scrubbed in the exact duration. The usability questionnaire filled by participants showed they were strongly agreed for its usefulness and agreed for its satisfaction and easiness.

Sensitivity of infrared sensor faucet on different skin colours and how it can potentially effect equity in public health

“…Hand hygiene is essential to human health and day-to-day activities. Maintaining proper hand hygiene can help reduce pathogen growth and transmission of diseases (Fitriyah et al, 2018). This activity should happen before and after handling food, eating, and using the toilet (Hantrakul et al, 2017).…”

“…As a result, his findings suggested that the automated dispensers may increase the rate of handwashing (Wong, 2008). Much of the literature has stated that handwashing is the most abundant task that people do every day, and the amount of water used is countless (Fitriyah et al, 2018). The WHO guidelines and other research indicates for standard handwashing procedures that one should obtain enough soap to cover all surfaces of the hand and rinse with warm water for 20 to 30 seconds, but barely 50% of the population can adhere to that standard (Fitriyah et al, 2018;WHO, n.d.).…”

The design of an automated dispenser would help conserve the amount of water while achieving satisfactory results of hand hygiene due to the preprogrammed design rates (Fitriyah et al, 2018;Widyaningrum, 2020).…”

Low Cost Sensor Based Hand Washing Solution for COVID-19 Prevention

“…The authors in [13,14] built a solar-powered, automated water tap prototype. The system detects human hand presence using an ultrasonic sensor and an Arduino It instructs the relay to activate the solenoid valve and allow water to flow by sending "on" and "off" commands.…”
