A Clock Inspired by Failed Cognitive Tests
A new clock design has been inspired by the clock-drawing test used to screen for cognitive impairments. This clock features a disordered face with numerals only on the right side, reflecting potential cognitive issues. It utilizes modern technology to minimize power consumption while maintaining functionality.
- ▪The clock-drawing test is a simple screening tool for cognitive impairment, particularly dementia.
- ▪The newly designed clock has numerals placed exclusively on the right half of the face, indicating possible cognitive disorders.
- ▪The clock is powered by a servo motor and an ESP32-C3, designed for low power consumption.
