TACT is a dual-terminal service communication system for table-service restaurants. It responds to a quiet but common problem in solo dining: the moment when a small need has to become visible in public. Asking for water, ordering, requesting the bill, or raising an issue can feel awkward when the diner has to wave, wait, or repeatedly look around for staff.

TACT connects a table-side tray with a waiter-side wearable interface. The diner makes a discreet request through a deliberate touch interaction, while the watch translates that request into a readable staff-side queue. The system does not replace hospitality. It supports the moment before service can happen: noticing.
