Multimodal "Sensory Illusions" for Improving Spatial Awareness in Virtual Environments

Glyn Lawson, Tessa Roper, Che Abdullah
2016 Proceedings of the European Conference on Cognitive Ergonomics - ECCE '16  
Multimodal feedback can improve depth perception in VEs, but this has yet to be implemented and tested in engineering applications with systems which provide haptic feedback to the body.  ...  Inaccurate judgement of distances in virtual environments (VEs) restricts their usefulness for engineering development, in which engineers must have a good understanding of the spaces they are designing  ...  ACKNOWLEDGMENTS This work was supported by the Engineering and Physical Science Research Council (EP/N00549X/1).  ...

The Third Joint Eurohaptics Conference and Symposium on Haptic Interfaces for Virtual Environment and Teleoperator Systems

2008 IEEE robotics & automation magazine  
The three commercial haptic devices we used span the cost spectrum, supposing that cost of a device is correlated with the fidelity of its virtual textures. This turned out not to be the case.  ...  Further investigation into the electrical and mechanical device properties that limited the performance of these devices revealed that D/A resolution, amplifier non-linearity and stiction were the primary  ...  ACKNOWLEDGEMENTS This work was supported in part by Sandia National Laboratories.  ...
