Abstract
A model for the mechanism of integration for vibrotactile and force cues in the haptic modality is important to facilitate task performance of human users in a three-dimensional (3D) virtual environment (VE). To investigate this mechanism, the research in this thesis used maximum likelihood estimation (MLE) and proposed proportional likelihood estimation (PLE) as the models of the integration. Two significant findings are as follows: (1) I found that based on the task accuracy, MLE was unable to integrate vibrotactile and force cues despite its ability to integrate cues of different modalities in literature; (2) Integration with PLE revealed that the mechanism of integration of vibrotactile and force cues may not be entirely additive as assumed in MLE. This work sheds an insight for proper model of integration between vibrotactile and force cues for interactive tasks in VEs.
