In this paper, we devote to provide teachers andstudents with short-range wireless learningenvironment. The wireless learning platform consistsof wireless handheld devices (PDA, notebook, etc.)carried by the guide and learners. A Content-basedimage retrieval system (CBIR) is constructed toprovide learner with required information using imagerecognition and wireless transmission technologies,such that the objective of outdoor ecology learning canbe achieved. A firefly database is used as an instanceto illustrate the operations of CBIR system. Instead oflearning from textbook, a real firefly in naturalenvironment can be observed and learned throughdigital camera and image recognition system. Duringthe learning activity, the teacher can use this CBIRsystem to control the learning progress, evaluate thelearning effects and provide necessary assistances tostudents in order to have a flourish learningenvironment.
