A Wearable RFID-Based Navigation System for the Visually Impaired
Recent studies have focused on developing advanced assistive devices to help
blind or visually impaired people. Navigation is challenging for this
community; however, developing a simple yet reliable navigation system is still
an unmet need. This study targets the navigation problem and proposes a
wearable assistive system. We developed a smart glove and shoe set based on
radio-frequency identification technology to assist visually impaired people
with navigation and orientation in indoor environments. The system enables the
user to find the directions through audio feedback. To evaluate the device's
performance, we designed a simple experimental setup. The proposed system has a
simple structure and can be personalized according to the user's requirements.
The results identified that the platform is reliable, power efficient, and
accurate enough for indoor navigation.Comment: 6 pages, 6 figures, 3 table
Evaluating Attentional Impulsivity: A Biomechatronic Approach
Executive function, also known as executive control, is a multifaceted
construct encompassing several cognitive abilities, including working memory,
attention, impulse control, and cognitive flexibility. To accurately measure
executive functioning skills, it is necessary to develop assessment tools and
strategies that can quantify the behaviors associated with cognitive control.
Impulsivity, a range of cognitive control deficits, is typically evaluated
using conventional neuropsychological tests. However, this study proposes a
biomechatronic approach to assess impulsivity as a behavioral construct, in
line with traditional neuropsychological assessments. The study involved
thirty-four healthy adults who completed the Barratt Impulsiveness Scale
(BIS-11) as an initial step. A low-cost biomechatronic system was developed,
and an approach based on standard neuropsychological tests, including the
trail-making test and serial subtraction-by-seven, was used to evaluate
impulsivity. Three tests were conducted: WTMT-A (numbers only), WTMT-B (numbers
and letters), and a dual-task of WTMT-A and serial subtraction-by-seven. The
preliminary findings suggest that the proposed instrument and experiments
successfully generated an attentional impulsivity score and differentiated
between participants with high and low attentional impulsivity.Comment: 10 pages, 5 figures, 5 table
