“…With a focus on DT, we developed a new concept called the Dual-Task Tai Chi (DTTC) test [ 8 ]. This system was developed using Kinect (Microsoft, Redmond, WA, USA), a motion-capture device, and demonstrated that the DTTC test quantitatively evaluates compound functions, including DT, balance, and cognitive abilities in elderly people [ 9 ]. In unpublished data, we found that DTTC training was useful not only to assess but also to improve balance and mobility among elderly people [ 10 ].…”

BackgroundDecrease of dual-task (DT) ability is known to be one of the risk factors for falls. We developed a new game concept, Dual-Task Tai Chi (DTTC), using Microsoft’s motion-capture device Kinect, and demonstrated that the DTTC test can quantitatively evaluate various functions that are known risk factors for falling in elderly adults. Moreover, DT training has been attracting attention as a way to improve balance and DT ability. However, only a few studies have reported that it improves cognitive performance.ObjectiveThe purpose of this study was to demonstrate whether or not a 12-week program of DTTC training would effectively improve cognitive functions.MethodsThis study examined cognitive functions in community-dwelling older adults before and after 12 weeks of DTTC training (training group [TG]) or standardized training (control group [CG]). Primary end points were based on the difference in cognitive functions between the TG and the CG. Cognitive functions were evaluated using the trail-making test (part A and part B) and verbal fluency test.ResultsA total of 41 elderly individuals (TG: n=26, CG: n=15) participated in this study and their cognitive functions were assessed before and after DTTC training. Significant differences were observed between the two groups with significant group × time interactions for the executive cognitive function measure, the delta-trail-making test (part B−part A; F 1,36=4.94, P=.03; TG: pre mean 48.8 [SD 43.9], post mean 42.2 [SD 29.0]; CG: pre mean 49.5 [SD 51.8], post mean 64.9 [SD 54.7]).ConclusionsThe results suggest that DTTC training is effective for improving executive cognitive functions.Trial RegistrationJapan Medical Association Clinical Trial Registration Number: JMA-IIA00092; https://dbcentre3.jmacct.med.or.jp/jmactr/App/JMACTRS06/JMACTRS06.aspx?seqno=2682 (Archived by WebCite at http://www.webcitation.org/6NRtOkZFh).

“…This simple feedback makes it almost impossible to discern the specific corrections required in each posture. The Dual-Task Tai Chi game suffers from similar limitations, but with more interesting game play [23], using Kinect T M -based full-body control with a cognitive task, i.e., 4x4 Sudoku. In this game, the user has to reach a specific posture in order to select a number with the right hand or foot, and then place this number on the Sudoku grid with the left hand or foot.…”

Numerous serious exergames advocate the use of engaging avatars to motivate a consistent exercise regimen. However, the process of specifying the prescribed exercise, implementing it as avatar animation, and developing an accurate feedback-providing mechanism is complex and requires a high level of expertise in game engines, control languages, and hardware devices. Furthermore, in the context of rehabilitation exergames, the requirements for accurate assessment and timely and precise feedback can be quite stringent. At the same time, the Kinect T M motioncapture sensor offers a natural interface to game consoles, and its affordability and wide availability represents a huge opportunity for at-home exergames. In this paper, we describe our work towards a system that envisions to simplify the process of developing rehabilitation exergames with Kinect T M. The system relies on a language for specifying postures and movements between them, and includes an editor that enables rehabilitation therapists to specify the prescribed exercise, by editing a demonstration of the exercise. This exercise-specification grammar is used to drive the animation of an avatar and the provision of quality feedback, by comparing the player's postures (as captured by the Kinect T M) against those of the coaching avatar and the grammar.

Significant differences were observed between the two groups with significant group × time interactions for the executive cognitive function measure: Δtrail-making test (part Bpart A) (p < 0.05). The results suggest that DTTC training is effective for improving executive cognitive functions.
