- Haptics, the interaction between people and their surrounding environment through touch, has allowed for various possibilities of information processing. Different forms of haptics include vibration (such as in phones to signal a notification), pressure change, and resistance. However, it is unclear how people utilize haptic feedback with other senses such as vision. While haptics can provide an additional route for information processing that allows for a larger amount of feedback to be leveraged for task assistance, it is unclear how people utilize haptic feedback with other senses such as vision. This thesis compares the ability to distinguish and respond to haptic and visual movement cues to determine their accuracy to communicate a motion. This experiment had participants replicate a specified movement based on the cues provided that measures angle and distance accuracy. Various direction cues and distance cues were given for three different feedback conditions: visual, haptic, and a combination of visual and haptic. The results showed that the combination of visual and haptic feedback had a significant impact on motion accuracy. There was a significant interaction of feedback condition and angle cue based on angle error and there was a significant interaction of feedback condition and distance cue based on distance error. These findings demonstrate that there is a need to consider how different forms of feedback communication interplay with one another, in order to use these feedback mechanisms to a greater potential.
