Prompt: On/Off Switch

Consider what's being turned on/off and how it should be done. 

Is it a push-to-start electric vehicle? A control panel for a smart refrigerator or some other touch panel display? 

UI based off the Apple Watch Ultra. I utilized the Apple UI interface/iconography and made small UI design changes, but focused on better accessibility design. Adopted a larger power button as it can rather difficult to press as well as the slide functionality has been increased to also accommodate those with larger fingers. This update in design will, hopefully, improve the quality of life for accessibility in users of different finger sizes. I will go on to say the push power off button will be there by default and in the future have Siri be able to turn off the watch via voice command to accommodate those who may have certain disabilities may not allow them to utilize their hands. Enjoy!
