The 'man-object' interaction is a subject of great interest for the practice of Design and Ergonomics, as it deals with both physical and perceptual aspects. The main objective of the present study was to carry out an evaluation with simulated activities to verify if the shape and color of the packages influence the perceptual aspects of the usability and the transmission of manual gripping force. Six experiments were carried out involving 120 Brazilian and 120 Portuguese subjects, equally divided among youth, adults and elderly; and between men and women. The methodological procedures were based on inductive reasoning, characterized by a cross-sectional study with laboratory experimentation. Five packages were selected for the test in Brazil and another 5 packages with similar features for the test in Portugal. The results indicate that the expenditure of more time to perform a task, not always, implies a lower user satisfaction. The more rigid materials were related to a better product quality. The presence of a curved area in the packaging was a positive factor, however it cannot be below the center. The very low cap was related to the greater difficulty of use. The efficiency of the elderly was significantly lower in all cases. Different diameters do not influence the pouring act, but directly influence the perception regarding the ease of accomplishment of the task. The determining factors for the positioning of the hands were the center of mass and the shape of the product. In all cases men exerted forces significantly higher than women. The mean strengths of the elderly were significantly lower in all cases. Higher caps (12mm and 13mm) allowed better application of forces. The red packaging was related to the greatest effort to be applied in the opening. However, there was no significant difference when the blue and transparent bottles were compared to each other. It was concluded that the shape and color of the packaging were factors that influenced the perceptual aspects and the biomechanical interaction. The same was observed with respect to the different genders and age groups. (AU)
