Abstract

As the need for sensors increases with the inception of virtual reality, augmented reality and mixed reality, the purpose of this paper is to evaluate the suitability of the two Kinect devices and the Leap Motion Controller. When evaluating the suitability, the authors’ focus was on the state of the art, device comparison, accuracy, precision, existing gesture recognition algorithms and on the price of the devices. The aim of this study is to give an insight whether these devices could substitute more expensive sensors in the industry or on the market. While in general the answer is yes, it is not as easy as it seems: There are significant differences between the devices, even between the two Kinects, such as different measurement ranges, error distributions on each axis and changing depth precision relative to distance.

Highlights

  • The technical side of the devices is reviewed, starting with device comparisons found in the literature

  • Devices in the same price range and more expensive ones are compared with the Kinects and the LMC

  • In this field people use Light Detection and Ranging (LiDAR) sensors which consist of Terrestrial Laser Scanners (TLS) or Mobile Terrestrial Laser Scanners (MTLS)

Three hundred and seventeen (317) records were excluded as neither their titles nor their abstracts referred to the state of the art, motion tracking, gesture recognition, the accuracy or precision of the devices. 108 full-text articles assessed for eligibility which consisted of a content analysis Based on their content, 14 full-text articles were excluded as those articles did not give significant information about the state of the art, motion tracking, gesture recognition, accuracy or precision. 14 full-text articles were excluded as those articles did not give significant information about the state of the art, motion tracking, gesture recognition, accuracy or precision Out of these 14 articles, four were shorter versions of extended papers.
