Evaluation of voice commands for mode change in virtual reality implant planning procedure

Abstract

Purpose In dental implantology, the optimal placement of dental implants is important to meet functional and aesthetic requirements. Planning dental implants in virtual three-dimensional (3D) environment is possible using virtual reality (VR) technologies. The three-dimensional stereoscopic virtual reality environment offers advantages over three-dimensional projection on a two-dimensional display. The use of voice commands in virtual reality environment to replace button presses and other simple actions frees the user’s hands and eyes for other tasks. Methods Six dentomaxillofacial radiologists experimented using a prototype version of a three-dimensional virtual reality implant planning tool, and used two different tool selection methods, using either only button presses or also voice commands. We collected objective measurements of the results and subjective data of the participant experience to compare the two conditions. Results The tool was approved by the experts and they were able to do the multiple-implant planning satisfactorily. The radiologists liked the possibility to use the voice commands. Most of the radiologists were willing to use the tool as part of their daily work routines. Conclusion The voice commands were useful, natural, and accurate for mode change, and they could be expanded to other tasks. Button presses and the voice commands should be both available and used in parallel. The input methods can be further improved based on the expert comments.

Application of virtual reality in dental implants: a systematic review

“…To evaluate the virtual reality in the identified studies, three things have been examined in most of the studies, which include user-friendliness of the system, usability and user satisfaction [ 9 , 37 , 39 , 45 ]. In a study to evaluate the usability of interaction methods according to the ISO definition, three dimensions were examined, including efficiency (task completion time), effectiveness (marking consistency) and satisfaction (subjective evaluations).…”

“…Also, the number of implants removed and released was counted [ 40 ]. It also refers to ease of learning and ease of performance [ 37 , 39 , 45 ]. Also, to evaluate the functional skills of the dental implant, the duration of implant placement, the final positions of the implant, the number of removal and release of the implant, and the number of times the participants used voice commands [ 45 ].…”

Among other things evaluated, the visual and tactile originality of the virtual environment.…”

“…Also, the degree of performance improvement after using the system, and compared with the traditional method. Questionnaires and surveys were used to evaluate these items [ 29 , 37 , 39 , 40 , 45 ].…”
