This paper discusses navigation services utilizing 3-dimensional maps for pedestrians. We conduct two kinds of experiments. The first compares the understandability of 2- and 3-dimensional maps with different display sizes corresponding to PDAs (Personal Digital Assistants) and mobile phones. Our results indicate that 3-dimensional maps are much easier to understand than conventional 2-dimensional maps and that understandability is affected by display size. The second one deals with improving understandability of 3-dimensional maps on small display screen and it is based on the "compensation method", which we proposed in a previous report. The compensation method adjusts parameters, such as contrast and view angle, through statistical procedures. Our findings show that the understandability of 3-dimensional maps can be improved significantly, compared with a case of usual parameter values.
