An integrated, computer vision-based system was developed to operate a commercial wheelchair-mounted robotic manipulator (WMRM). In this paper, a gesture recognition interface system developed specifically for individuals with upper-level spinal cord injuries (SCIs) was combined with object tracking and face recognition systems to be an efficient,(More)
With the advent of new gaming technologies, hand gestures are gaining popularity as an effective communication channel for human computer interaction (HCI). This is particularly relevant for patients recovering from mobilityrelated injuries or debilitating conditions who use gesture-based gaming for rehabilitation therapy. Unfortunately, most gesturebased(More)
Hand gesture-based interfaces have become increasingly popular as a form to interact with computing devices. Unfortunately, standard gesture interfaces are not very usable by individuals with upper limb motor impairments, including quadriplegics due to spinal cord injury (SCI). The objective of this paper is to convert an existing interface to be usable by(More)
An innovative 3D joystick was developed to enable quadriplegics due to spinal cord injuries (SCIs) to more independently and efficiently operate a robotic arm as an assistive device. The 3D joystick was compared to two different manual input modalities, a keyboard control and a traditional joystick, in performing experimental robotic arm tasks by both(More)
A gesture recognition based interface was developed to facilitate people with upper extremity physical impairments as an alternative way to perform laboratory experiments that require ‘physical’ manipulation of components. A color, depth and spatial information based particle filter framework was constructed with unique descriptive features for face and(More)
This paper presents a hand gesture-based interface to facilitate interaction with individuals with upper-level spinal cord injuries, and offers an alternative way to perform “hands-on” laboratory tasks. The presented system consists of four modules: hand detection, tracking, trajectory recognition, and actuated device control. A 3D particle filter framework(More)
Gesture-based interfaces have become an effective control modality within the human computer interaction realm to assist individuals with mobility impairments in accessing technologies for daily living to entertainment. Recent studies have shown that gesture-based interfaces in tandem with gaming consoles are being used to complement physical therapies at(More)
