In China, food delivery workers are a large occupation. People are accustomed to their fast and efficient service, but the safety hazards behind the pursuit of extreme speed are rarely noticed. According to the working mode and behavioural habits of this specific target group, a functionally integrated helmet supported by a mobile phone was designed. With the method of interaction system optimization to simplify the food delivery process, the work efficiency was improved while ensuring safety factors.
