	%X The objective of this paper is to investigate a new
approach based on the idea of pictograms for food portion size. This
approach adopts the model of the United States Pharmacopeia- Drug
Information (USP-DI). The representation of each food portion size
composed of three parts: frame, the connotation of dietary portion
sizes and layout. To investigate users- comprehension based on this
approach, two experiments were conducted, included 122 Taiwanese
people, 60 male and 62 female with ages between 16 and 64 (divided
into age groups of 16-30, 31-45 and 46-64). In Experiment 1, the mean
correcting rate of the understanding level of food items is 48.54%
(S.D.= 95.08) and the mean response time 2.89sec (S.D.=2.14). The
difference on the correct rates for different age groups is significant
