Abstract

A human-machine interface (HMI) refers to the point at which a human interacts with a machine, whether it be a physical device or a software program. The interface can take many forms, such as a keyboard, mouse, display, touchscreen, or voice recognition system. The goal of a machine interface is to facilitate communication between the user and the machine, allowing for efficient and effective use of technology. In recent years, there has been a shift towards more intuitive and natural interfaces, such as gesture recognition and augmented reality, which seek to make the interaction between human and machine more seamless. As technology continues to evolve, the design and development of machine interfaces will play a crucial role in shaping how humans interact with machines and ultimately impact our daily lives. Some general e-buggy problems are no information display, limited info also less automation and digitalization. Raspberry pi will be used in this project to design an interface for e-buggy. According on the responses provided by 40 survey participants, the colour choice for the metre gauge was made. In this project, the HMI is developed for the e-buggy towards engineering tools such as Pugh Method or Decision Weighted Matrix is to be used for HMI design. Information on the powertrain performance can be monitored for efficient operation. As the result, an intuitive HMI is developed based on user evaluation rating. Moreover, Altair Inspire also will be used in this project to analysis of car dashboard. In this section, results for analysis of displacement, safety of factor, and von misses stress in car dashboard can be calculated. As a result, the objective of getting a car dashboard that is safe and friendly for drivers to use can be realized. In conclusion, the project demonstrates a comprehensive approach to HMI design, utilising engineering techniques in addition to user preferences to provide a well-balanced blend of safety, practicality, and aesthetics in the dashboard of an e-buggy vehicle.
