"Objectifying Visual Perception for Automotive Screens through Vibration Targets"

New mobility concepts with smart infrastructure have led to enhanced customer driving experience. The potential to develop safe cars with minimal driver intervention is a great need of the future. The cusp for fully autonomous driving has produced much technical talk, which has led to faster transition and adoption. One of the features that global OEMs have tried to focus on, is Human Machine Interface (HMI) solutions, popularly called display screens. The touchscreen HMIs are common in all mid-range budget cars. They offer driver support beyond just streaming music, including inputs for navigation, parking assistance, in-car technologies, ADAS, and infotainment. Poor display screen visibility is a phenomenon observed when a vehicle is driven over different road surfaces. This paper presents a user-centric approach for the right design & development of the HMI for a vibration free driving experience. The mounting strategies for the display screens, from the existing projects were considered and analyzed for diverse levels of excitation and response levels are recorded to check blurred vision. Target strategy was achieved based on the best results obtained from the tested vehicles. The design is optimized for meeting the targeted response levels and the minimal mounting strategy is standardized for this model of HMI as this was designed with a unique concept of floating screen. Best simulated design is validated with test to enhance HMI visual display perception.
