The project simply consists of adding a new interface (a display / showcase screen) to an existing appointment booking website. This website already contains barbers’ calendars, where clients can book time slots (for example from 1:00 PM to 2:00 PM for a haircut). In the barbershop, there will be a mirror screen that displays the appointments. The principle is the following: • When a client books a time slot on the website, the appointment automatically appears on the mirror screen. • However, if the barber modifies something directly in the calendar (changing the service, modifying the time, etc.), these modifications should not appear on the mirror screen. In summary: The mirror screen is only a showcase interface that displays the appointments booked by clients, without showing the internal changes made by the barber in the calendar.
