DEVELOPMENT OF VEHICLE INFOTAINMENT DISPLAYS BASED ON LEGIBILITY AND READABILITY REQUIREMENTS 2020-28-0321

Vehicle infotainment displays are the displays that the driver need to look at during driving for getting critical information or entertainment related information’s. It can be seen that the time available to glance these screen while driving is very less and it is directly related to the driving safety. Hence it is critical to have these displays readable and legible. The legibility and readability of text, pictures on the display screens (Includes the instrument cluster and center console displays) is critical since it is combination of the available space and geometric constraints. The instrument cluster position is constrained by the instrument panel packaging and size / diameter of the dials of instrument cluster. Hence the text size should be decided based on the position of display which will be legible and readable for all target population users from their designated seating position. This paper discusses the position and geometric constraints for designing the driver information displays and deriving the legibility and readability requirements based on the user seating positions. International standards are used to set the target for legibility of text in dynamic condition such as moving vehicle. RAMSIS and SPEOS OPTIS software are used to get the occupant sitting position and legibility study done for different vehicle conditions.
