People are susceptible to commit substitution errors due to some
similar features of visual signals,and it invloves issues of
safty and performance.This research tried to investigate the
confusion degrees of Chinese characters pairs with antonymous
meaning and basic geometric figures.We intend to develop an
objective testing technique on selecting less confused
characters and figures for practical use.Based on the
recognition rate of the Experiment 1, 16 characters pairs could
be divided into five groups and of which a confusion scale was
composed.On this scale,Degree 1 was respresented by the most
confused「開 (k''ai / on)、關 (kuan / off)」pairs ; Degree 2 by「
粗 (ts''u / thick) 、細 (hsi / thin)」、「寬 (k''uan / broad)、窄
chai / narrow)」; Degree 3 by「推 (t''ui / push)、拉 (la / pull)
」、「合 (ho / assemble)、分 (fen / separate)」; Degree 4 by「水
(shui / water)、 火 (huo / fire)」、「前 (ch''ien / front)、後
(hou / back)」and Degree 5 by「切 (ch''ieh / off)、入 (ju / on)」
、「方 (fang / square)、圓 (yuan / circle)」the less confused.
The preliminary influence considered characters contoux,strockes
members,and detail configuration as determinants of
recognizability or confusion.In Experiment 2,the recognizability
of the basic geometric figures tested were showed significantly
different,and a symmetry confusion existed among hexagon,
octagon,and circle.A confusion scale with five degrees could be
established as following: : Degree 1,the most confused octagon ;
Degree 2,ellipse and rectangle ; Degree 3,hexagon and circle ;
Degree 4,square and lozenge,and Degree 5 ,the less confused
triangle. The preliminary influence considered line,curve,angle,
symmetry and number of angles as determinants of recognizability
and hence possibility of confusion.
