Outline of Final Research Achievements

Precise manual handling skills are necessary to create art and to paint models. However, these skills are difficult to learn. In our research, we propose a system using pseudo-haptics to support accurate work without using any mechanical devices. We considered the principle that when a pseudo-haptic force is generated on a user’s hand in the opposite direction of a target path, the user moves her/his hand to the right direction reflexively to repel the force. Based on this idea, we created a system that can modify users’ hand movement by showing a dummy hand using a mixed reality display, which supports precise manual-handling tasks. The results showed that an expansion of the deviation between the target route and the actual hand position improved accuracy up to 50%. According to experimental results, we find that a gain of about 2.5 gives an ideal balance between the working precision and the drawing speed.
