Display is the most important things to get information in particularly for Tourism Park. A good display will increase effectiveness and efficiency in reading as well as alleviate uncertainty on information. Thus the design should be clear and able to identify easily about the real environment. This paper develop design of display which can result in expeditious response in human information processing. Empirical study was conducted to determine reaction time as the physiological parameter of human respond by using a software developed with Java. Two categories of information used were accessibilities and public facilities. A case study is Pindul Cave Tourism where 12 male and 8 female was participated in this experiment. The result shows that response time to process the information of alternative design was 1.16 second to 1.30 second. Furthermore, design by using combination of text and symbol was easier to understand than text or symbol with 0.2 second of lapse time. There were significant differences in reaction time among colour combinations which white for background and black for object with 91% of contras value has longer time then with 74% of contras value of green for background and red for object. While the design by using large size was not more effective than other size for information display.
