LAYOUT DESIGN FOR DATA MANAGEMENT OF ELECTRIC VEHICLE SPEEDOMETER IN THAILAND

Abstract

The research objective is to study the layout design for data management of electric vehicle speedometer in Thailand. This survey research uses questionnaires and the Item-Objective Congruence Index as a data collection tool. The data is collected through a single measurement. The sample population consists of electric vehicle users in Thailand whose vehicles are priced at no more than 1,500,000 baht, have been used continuously for at least 6 months, are between the ages of 20 and 40 years, and travel approximately 30 to 60 kilometers per day. A specific targeted sampling approach is employed. The data is collected and summarized to analyze and draw conclusion. The research findings indicate that the layout design of model 1 which utilizes an overall area for displaying data of 75.144%, received the highest popularity score. This design is capable of displaying data on meters greater than 75% of the total area, resulting in a 25% increase in display rate when compared to electric car meters currently available in Thailand and priced at no more than 1,500,000 baht. The layout design of the meter is based on the golden ratio theory allowing the sample group to comprehend information, understand its significance, and enhance confidence in safely driving electric cars in Thailand.
