Scientists
have come up with the most advanced and intelligent wheelchair system
known as "iWheelchair." With just a tablet computer as the central
operating platform, the system has integrated a range of functions such
as safety, environment control, hygiene and health monitoring with
automated alerts that cater to the requirements of users and decrease
workload on the caregivers.
By
giving simple touchscreen commands, users can easily control any home
device that is connected to the system, such as TV, electric curtains,
electric beds and motorized projector screens. Those suffering from hand
impairments can use a fabric electronic switch to translate thumb
movements into touchscreen commands. In addition, a sensor fixed to the
wheelchair constantly evaluates vital health signals like heart rate,
and saves the readings into a computer for future record, while the fall
monitoring system can activate instant alarm when the wheelchair or the
patient falls.
The
cushion seat and diaper wrap is made out of nano-treated fabric
comprising of water repellent, dirt-proof, and antibacterial features.
The seat also has fabric sensors that evaluate the user's posture and
alerts the user of prolonged inactivity to avoid circulatory problems or
bedsores. The entire system is also attached to a smart diaper
containing sensors that can sense moisture levels and puts on a buzzer
on the computer tablet when there is a need for a change. Apart from
this, there are several optional settings available for sending SMS,
email alerts to the concerned family members or caregivers in case of
prolonged inactivity, a fall, wet diaper or abnormal heart rate.
The
system makes use of Bluetooth to establish communication among all the
sensors. Apart from this, the system can be personalized to cater to the
requirements of individual patients.
The
research team working on the iwheelchair project will continue to work
to make sure iWheelchair is able to cope with the daily challenges faced
by those using a wheelchair. This is to make sure that the technology
is able to help wheelchair users of all communities around the world.
The PolyU technologies that have been deployed in the iwheelchair system include:
- Integrated Control System (tablet based)
- System to Monitor Falls
- System to Monitor Vital Signs
- Fabric Sensor
- Smart Diaper
- Fabric Electronic Switch
Technology has come a long way and its certainly helping those with physical in capabilities. iWheelchair
is a revolutionary concept that will make living easier not just for
the one using the wheelchair but also for the care givers. The project
has even won a bronze medal in International Invention Fair in Seoul.
