Tangible information can be perceived by any of the five senses and requires the presence of material objects.
Tangible information is the less perceivable properties of material objects that are not as obvious as striking features. The effects of tangible information can be demonstrated and understanding the effects does not require the use of words or ideas.
The tangible information is defined as visual patterns, surface appearances and spatial fit. The effects of their motor actions are classified as primary and secondary effects.
Attention is also captured by the degree of effects that variations in their actions cause in making small and increasingly better improvements and by anticipating what might happen to tangible information. This is commonly referred to as overt trial and error.
