Individuals with mild cognitive impairment (MCI) experience challenges completing hygienic tasks independently due to short-term memory loss and difficulties sequencing tasks together. A caregiver can help by providing reminders and cueing. However, dependency on a caretaker decreases independence which may impact self-confidence.

This smart bathroom mirror, shown in Figure 1, may help individuals with MCI to complete hygienic tasks, supporting independent living. The focus tasks are brushing teeth, flossing teeth, washing face, washing hands, applying deodorant, and brushing hair. The smart mirror reminds the users of their daily hygiene tasks and will proceed with step-by-step cueing when the user activates a task using the keypad.

The smart mirror incorporates a custom-built hardwood frame containing a panel of smart mirror glass and a Dell 27" 2722 monitor. A PIR motion sensor, a 9-button keypad, and a Raspberry Pi 3 B+ connect to the monitor. The material of the back panel is Medium Density Fibreboard (MDF) which is secured using screws, allowing access to the internal electronics when needed. Brackets with screws fasten the smart mirror to the wall. The languages used to program the smart mirror are HTML, CSS, and JavaScript.

There were eight tests; of particular interest are the internal heat and humidity tests that ensure the smart mirror's internal temperature remains below 40 °C and relative humidity (RH) does not exceed 30%. The design team also tested the functionality of the smart mirror to confirm that smart mirror technology could effectively cue hygiene tasks.

The main recommendation is for testing to occur with individuals who live with MCI to conclude the effectiveness of a smart mirror in increasing the independence of this population. In addition, recommendations to improve the physical build and software are made.
