Motor performances in some of the neurological diseases such as stroke, multiple sclerosis, and Parkinson's are damaged. Improvement of this deficiency typically requires intensive treatments in a long period of time. Although various rehabilitation techniques could be used for this purpose, among them the Human-Computer Interaction (HCI) based met...

The heterogeneity of stroke prompts the need for predictors of individual treatment response to rehabilitation therapies. We previously studied healthy subjects with EEG and identified a frontoparietal circuit in which activity predicted training-related gains in visuomotor tracking. Here we asked whether activity in this same frontoparietal circui...

Background and Aim: Advances in neuroscience have provided a potential to directly interact with the human brain. Interaction with human brain could be performed using neuroimaging techniques such as EEG to build a brain computer interface (BCI). The EEG-based BCI systems are now mature enough to be applied in HCI researches to promote novel techni...

In recent years, the field of Human-Computer Interaction (HCI) has been advanced with many technologies, however, most are limited to healthy users. In this paper, we leveraged the technology of free-hand interaction to rehabilitate patients with stroke. We modified the game of Fruit Ninja to use Leap Motion controller's hand tracking data for stro...

We explore the differences of direct (DI) vs. indirect (IDI) interaction in stroke rehabilitation. Direct interaction is when the patients move their arms in reaction to changes in the augmented physical environment; indirect interaction is when the patients move their arms in reaction to changes on a computer screen. We developed a rehabilitation...

We propose a tabletop keyboard that assists stroke patients in using computers. Using computers for purposes such as paying bills, managing bank accounts, sending emails, etc., which all include typing, is part of Activities of Daily Living (ADL) that stroke patients wish to recover. To date, stroke rehabilitation research has greatly focused on us...

We propose a novel multi-perspective multi-layer interaction using a mobile device, which provides an immersive experience of 3D navigation through an object. The mobile device serves as a window, through which the user can observe the object in detail from various perspectives by orienting the device differently. Various layers of the object can a...

Introducing computer games to the rehabilitation market led to development of numerous Virtual Reality (VR) training applications. Although VR has provided tremendous benefit to the patients and caregivers, it has inherent limitations, some of which might be solved by replacing it with Augmented Reality (AR). The task of pick-and-place, which is pa...

Full or partial loss of functionality of the upper limbs is usually associated with strokes, spinal cord injury and many other similar injuries. Traditional rehabilitation treatment however is extremely labor intensive and are usually only available at hospital. However a lot of studies have shown that through the use of repetitive robotic practice...

This paper features a Spatial Augmented Reality system for rehabilitation of hand and arm movement. The table-top home-based system tracks a subject's hand and creates a virtual audio-visual interface for performing rehabilitation-related tasks that involve wrist, elbow, and shoulder movements. It measures range, speed, and smoothness of movements...

Monitoring the ambience's condition is emerging as one of the most important issues in mobile robots. While we need to detect and process the condition quickly and efficiently using sensors, they (sensors) introduce extra complexity to the systems. Therefore this paper aims to develop a new method to simplify the sensing process. It describes an ex...
