"Even with an object in plain sight and in close proximity, there is a lot more in front of us than meets our eye. By observing an object using our sense of touch, we are able to gather an entirely different set of observable data about the object - in particular, the 3D form and detail of the object that would be entirely unavailable to sight-only observation".
Leonard Shapiro has developed a multi-sensory observation method, which employs the sense of touch as well as sight, coupled with the simultaneous act of drawing (i.e. mark-making). It is called the haptico-visual observation and drawing (HVOD) method. In anatomy study, the benefits of observing using the sense of touch includes i) enhanced observation of the 3D form of anatomical parts, ii) the cognitive memorization of anatomical parts as a 3D 'mental picture' and iii) improved spatial orientation within the volume of anatomical parts.

In 1987, Professor Roberta Klatzky and Professor Susan Lederman described a set of specialized patterns of manual exploration which they called exploratory procedures (EPs) or stereotypical patterns of hand movements. These exploratory patterns are linked to the acquisition of specific object properties.
When using the haptico-visual observation and drawing (HVOD) method for enhanced object observation, we actively apply these otherwise spontaneous EPs, coupled with the simultaneous act of making marks on paper which correspond to the EP gestures. In particular, we actively apply the following EPs: 'lateral motion', 'contour following' and 'enclosure'. The marks made to describe the EPs include what are referred to as 'cross-contour' and 'modelled marks'.
