Many people with disabilities utilize self propelled wheelchair with suspension control wheelchairs to get around. These chairs are ideal for daily mobility and can easily overcome obstacles and hills. They also have large rear shock-absorbing nylon tires which are flat-free.
The translation velocity of the wheelchair self propelled was measured using a local field-potential approach. Each feature vector was fed to an Gaussian encoder that outputs a discrete probabilistic spread. The accumulated evidence was then used to trigger visual feedback, as well as a command delivered after the threshold was reached.
Wheelchairs with hand rims
The type of wheel that a wheelchair is using can affect its ability to maneuver and navigate different terrains. Wheels with hand rims help relieve wrist strain and increase comfort for the user. A wheelchair's wheel rims can be made from aluminum, steel, or plastic and are available in a variety of sizes. They can be coated with vinyl or rubber to improve grip. Some are designed ergonomically, with features like shapes that fit the grip of the user and broad surfaces to provide full-hand contact. This lets them distribute pressure more evenly and avoid fingertip pressure.
Recent research has revealed that flexible hand rims can reduce impact forces on the wrist and fingers during activities during wheelchair propulsion. They also have a larger gripping area than standard tubular rims. This allows the user to exert less pressure while maintaining the rim's stability and control. They are available at most online retailers and DME suppliers.
The study's findings showed that 90% of respondents who had used the rims were happy with them. However it is important to note that this was a postal survey of people who purchased the hand rims from Three Rivers Holdings and did not necessarily reflect all wheelchair users who have SCI. The survey also didn't evaluate the actual changes in symptoms or pain, but only whether the individuals felt a change.
The rims are available in four different models which include the light, big, medium and prime. The light is round rim that has smaller diameter, and the oval-shaped medium and large are also available. The rims on the prime are slightly larger in diameter and have an ergonomically contoured gripping surface. All of these rims can be mounted on the front wheel of the wheelchair in a variety shades. They are available in natural light tan, as well as flashy blues, greens, reds, pinks, and jet black. They are quick-release and are able to be removed easily to clean or maintain. The rims are protected by vinyl or rubber coating to stop hands from sliding off and causing discomfort.
Wheelchairs with tongue drive
Researchers at Georgia Tech have developed a new system that allows users to move a wheelchair and control other electronic devices by moving their tongues. It is made up of a small tongue stud that has magnetic strips that transmit movements signals from the headset to the mobile phone. The smartphone converts the signals to commands that control the device, such as a wheelchair. The prototype was tested with able-bodied people and in clinical trials with those who suffer from spinal cord injuries.
To evaluate the performance, a group physically fit people completed tasks that assessed speed and accuracy of input. Fitts’ law was used to complete tasks such as keyboard and mouse use, and maze navigation using both the TDS joystick as well as the standard joystick. A red emergency stop button was built into the prototype, and a second participant was able to press the button when needed. The TDS worked as well as a normal joystick.
In a different test, the TDS was compared with the sip and puff system. This lets people with tetraplegia control their electric wheelchairs self propelled through blowing or sucking into straws. The TDS performed tasks three times more quickly, and with greater accuracy than the sip-and-puff system. In fact the TDS was able to drive a wheelchair more precisely than even a person suffering from tetraplegia, who is able to control their chair using a specially designed joystick.
The TDS was able to track tongue position with an accuracy of less than a millimeter. It also included camera technology that recorded eye movements of an individual to identify and interpret their movements. Software safety features were also included, which verified the validity of inputs from users twenty times per second. If a valid signal from a user for UI direction control was not received for 100 milliseconds, interface modules immediately stopped the wheelchair.
The next step is testing the TDS on people who have severe disabilities. They are partnering with the Shepherd Center located in Atlanta, a hospital that provides catastrophic care and the Christopher and Dana Reeve Foundation to conduct the tests. They plan to improve their system's ability to handle ambient lighting conditions, to include additional camera systems, and to allow repositioning of seats.
Joysticks on wheelchairs
With a power wheelchair equipped with a joystick, clients can operate their mobility device with their hands without needing to use their arms. It can be placed in the middle of the drive unit or either side. It also comes with a screen to display information to the user. Some of these screens are large and have backlights to make them more visible. Some screens are small, and some may include pictures or symbols that can assist the user. The joystick can be adjusted to fit different sizes of hands and grips, as well as the distance of the buttons from the center.
As power wheelchair technology evolved and advanced, clinicians were able develop alternative driver controls that allowed clients to maximize their functional capabilities. These advances allow them to accomplish this in a manner that is comfortable for end users.
A standard joystick, for instance, is an instrument that makes use of the amount of deflection of its gimble to provide an output which increases with force. This is similar to the way video game controllers or accelerator pedals in cars work. This system requires excellent motor skills, proprioception, and finger strength in order to function effectively.
A tongue drive system is another type of control that uses the position of the user's mouth to determine the direction to steer. A magnetic tongue stud relays this information to a headset which can execute up to six commands. It is a great option for people with tetraplegia and quadriplegia.
In comparison to the standard joystick, some alternative controls require less force and deflection to operate, which is especially helpful for users who have limited strength or finger movement. Some can even be operated using just one finger, making them perfect for those who can't use their hands at all or have limited movement in them.
Additionally, certain control systems have multiple profiles that can be customized to meet the needs of each user. This is crucial for a new user who might require changing the settings frequently, such as when they feel fatigued or have a flare-up of a disease. It can also be helpful for an experienced user who wants to change the parameters that are set up for a specific environment or activity.
Wheelchairs with steering wheels
Self-propelled wheelchairs are designed for those who need to move around on flat surfaces as well as up small hills. They have large wheels on the rear to allow the user's grip to propel themselves. Hand rims enable the user to use their upper-body strength and mobility to move the wheelchair forward or backwards. Self-propelled wheelchairs can be equipped with a wide range of accessories, such as seatbelts that can be dropped down, dropdown armrests and swing-away leg rests. Some models can also be converted into Attendant Controlled Wheelchairs that can help caregivers and family members control and drive the wheelchair for those who need more assistance.
Three wearable sensors were affixed to the wheelchairs of participants in order to determine the kinematics parameters. The sensors monitored the movement of the wheelchair for the duration of a week. The wheeled distances were measured using the gyroscopic sensor attached to the frame and the one that was mounted on the wheels. To distinguish between straight forward movements and turns, the period of time in which the velocity difference between the left and the right wheels were less than 0.05m/s was considered to be straight. Turns were further studied in the remaining segments and turning angles and radii were derived from the wheeled path that was reconstructed.
This study involved 14 participants. Participants were tested on navigation accuracy and command latencies. They were asked to navigate the wheelchair through four different ways in an ecological field. During the navigation tests, sensors tracked the path of the wheelchair along the entire course. Each trial was repeated at least twice. After each trial, the participants were asked to choose the direction that the wheelchair was to move into.
The results showed that a majority of participants were able to complete the navigation tasks, even although they could not always follow correct directions. On average, they completed 47 percent of their turns correctly. The remaining 23% either stopped immediately after the turn, or wheeled into a second turning, or replaced by another straight movement. These results are comparable to those of previous studies.
