The physical basis of perceived heaviness requires consideration of the haptic perceptual system's role in controlling actions (the system's proper function) and the relation of an object's inertial properties to properties of the human movement system (the object's affordance). We show that the mass of a wielded object and particular scalar variables calculated from the object's inertia tensor combine linearly in determining perceived heaviness. The tensor-derived scalars reflect the symmetry and volume of the corresponding inertia ellipsoid. These measures bear directly on the object's wieldability, that is, on the patterning and level of muscular forces required to move the object in a controlled fashion.
对感觉到的重量的物理基础进行考量，需要考虑触觉感知系统在控制动作方面的作用（该系统的固有功能）以及物体的惯性属性与人体运动系统属性之间的关系（物体的可供性）。我们发现，被握持物体的质量以及根据物体惯性张量计算出的特定标量变量，在决定感觉到的重量时呈线性组合。从张量得出的标量反映了相应惯性椭球体的对称性和体积。这些度量直接关系到物体的可操作性，也就是说，关系到以可控方式移动该物体所需的肌肉力量的模式和水平。
