another graphical representation of the relative values of the attributes is a bar chart the present invention has several advantages over the sensory testing procedures previously employed to many subjects sensory perception is difficult to quantify numerically it is much easier to employ visual means to represent perception through use of colors and familiar shapes or graphs another advantage is the elimination of the need to perform arithmetic computations to determine whether the attributes add up to 100 percent having the software perform the computations ensure that the attributes add up to 100 while freeing the subjects from tiresome arithmetic computations referring to fig1 a simulated computer screen 100 is depicted and 9 different attributes 10 for flavor are presented 1 mintiness 2 coolness 3 sweetness 4 saltiness 5 bitterness 6 grittiness 7 burning biting tingling 8 bad after taste off taste and 9 other sensation the perception scale 20 is provided for each of the attributes with a u2212 and guides 30 provided to indicate relative proportion of the attributes the subject is asked to manipulate the relative position of the attributes after evaluating the stimulus the computing means then produces the pie chart 50 with the relative size of each value present preferably with the attribute also appearing in the proximity of the pie chart as depicted.
