Abstract: Based on the analysis of main characteristics of common interaction devices,we propose a series of device combinations for two-handed interaction in desktop VEs,which have the extensive adaptability and usability for bimanual interaction tasks.According to the requirement of common interaction task in VEs, and combined with the characteristics of device candidates,the devices respectively used by dominant hand and nondominant hand can be assigned to implement different interaction subtask.Through combining various single-handed interaction techniques,we design three types of two-handed interaction techniques adapted for typical combinations of desktop interaction devices.Furthermore a toolkit for development of twohanded interaction technique is building up. Finally,several applications based on these techniques are demonstrated.
