The purpose of this study is to compare the road conditions (straight road, winding road and hill road) with the hand grip pressure force and muscle fatigue for male and female drivers. Ten subjects were participated in this study. The force measurement and electromyography (EMG) responses were taken and evaluated by using the tactile grip and pressure measurement (Grip System) and Electromyography (EMG) device. The result indicated that the winding road produced more muscle fatigue and high hand grip pressure force compared than downhill road, hill up road, and straight road for both male and female subjects. The result compared the muscle fatigue and hand grip pressure force between the first 15 minutes and last 15 minutes of driving activity. The muscle fatigue increasingly high for the last 15 minutes compared to first 15 minutes. However, the hand grip pressure forces become high during the winding road for first 15 minutes of driving session. The muscle fatigue become high as the hand grip pressure force value is high. Furthermore, the male drivers exert higher hand grip pressure force and higher muscle fatigue compared to female drivers. This study can be used as a guideline for the future studies, primarily in solving the driving fatigue problem among the Malaysian’s drivers. The method of this study could also be used for early detection of driver fatigue issues. Indirectly, the findings could reduce the number of car accidents in Malaysia.

The main objective of this research is to compare the seating pressure during the driving session between twodifferent types of national cars. The objective of this research is to conduct object pressure distribution study ontwo different types of car seat using CONFORMat (model 5330) with system model CER2, compare and analyse theresults based on object pressure between both car seat. Twelve respondents participated a driving session withTekscanCONFORMat (model 5330) setup using the same route for both national car. We select two types of nationalcars equipped with automatic transmission for this research. The seat pressure on the subject along the journey isrecorded using TekscanCONFORMat Research 7.60 software. Later, comparison made with respect to the seatpressure experiencedby twelve respondents. The results shows different values of backand seat pressure recordedamong the twelve subjects. Lastly, the results are analysedand discussed at the end of this paper. Model B seatdesign has better ability to distribute evenly the pressure to both seat and back. However, results for Model Ashowed the pressure is more concentrated on the seat area.
