An experiment was conducted to investigate how performance of a reach, grasp and place task was influenced by added auditory and graphical cues. The cues were presented at points in the task, specifically when making contact for grasping or placing the object, and were presented in single or in combined modalities. Haptic feedback was present always during physical interaction with the object. The auditory and graphical cues provided enhanced feedback about making contact between hand and object and between object and table. Also, the task was performed with or without vision of hand. Movements were slower without vision of hand. Providing auditory cues clearly facilitated performance, while graphical contact cues had no additional effect. Implications are discussed for various uses of auditory displays in virtual environments. Categories and Subject Descriptors H.5.2.
