Application: Digital World Experience (DWE) in Service/Retail Industry
Description
DWE in service/retail industry
– At the hotel, the check-in is processed by AI
– At the convenience store, AI/robot manages payment, inventory, light cooking, and provide customer service. At the same time, it can track people’s faces and report a face in case of emergency for safety.
– Tracking people’s faces can also be used for customer service by remembering their preferences or by reading their facial expressions.
Devices
- Advanced form-factors with enhanced display resolution, power consumption, and computing capacity
