However, relatively less research has attempted to address these motor deficits, especially by taking advantage of advanced technology. To explore potential mechanisms for expanding accessibility to fine motor intervention for people with ASD, we present the design and implementation of a feasibility study of a novel Haptic-Gripper Virtual Reality System (Hg). Hg is capable of providing analysis and practice opportunities of fine motor skills in an adaptive and low-cost virtual environment with real-time auditory, visual, and haptic feedback. The Haptic Gripper in Hg can detect a user's grip force and hand location and provide haptic feedback to guide hand movement and grip control while completing several simple and engaging virtual fine motor tasks. We conducted a feasibility study with six children with ASD and six typically developing (TD) children and found that participants were interested in using the Haptic Gripper and could quickly get used to the system. Although the results are preliminary and limited, we observed medium to strong correlations between the proposed fine motor skill metrics and the scores achieved with a standardized fine motor skill test and improvements of participants in accuracy and steadiness of movement and force control. This study provides important guidance for future investigations of the Hg's potential for assessing and improving fine motor manipulation skills.<\/jats:p>","DOI":"10.1145\/3231938","type":"journal-article","created":{"date-parts":[[2018,11,16]],"date-time":"2018-11-16T13:08:54Z","timestamp":1542373734000},"page":"1-21","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":22,"title":["Design of a Haptic-Gripper Virtual Reality System (Hg) for Analyzing Fine Motor Behaviors in Children with Autism"],"prefix":"10.1145","volume":"11","author":[{"given":"Huan","family":"Zhao","sequence":"first","affiliation":[{"name":"Department of Electrical Engineering and Computer Science, Vanderbilt University, Nashville, TN"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhaobo","family":"Zheng","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, Vanderbilt University, Nashville, TN"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Amy","family":"Swanson","sequence":"additional","affiliation":[{"name":"Treatment and Research Institute for Autism Spectrum Disorders, Vanderbilt University, Nashville, TN"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Amy","family":"Weitlauf","sequence":"additional","affiliation":[{"name":"Treatment and Research Institute for Autism Spectrum Disorders, Vanderbilt University, Nashville, TN"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zachary","family":"Warren","sequence":"additional","affiliation":[{"name":"Treatment and Research Institute for Autism Spectrum Disorders, Vanderbilt University, Nashville, TN"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nilanjan","family":"Sarkar","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, Vanderbilt University, Nashville, TN"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"320","published-online":{"date-parts":[[2018,11,16]]},"reference":[{"key":"e_1_2_1_1_1","unstructured":"J.
