In the technologically developing world patients with some cognitive disabilities and impairment must be provided with smart wheelchair systems for their easy navigation and safety. This paper describes the wheelchair system with user friendly touch screen and joystick interface. Use of touch-screen enables less muscle movement and less muscular pressure than the self-propelled wheelchairs which are being used from ages. It enables a disabled person to move around independently using a touch screen application which is interfaced with motors through microcontroller. In order to change the direction, the touch screen sensor is modelled to direct the user to required destination using direction keys on the screen and that values are given to microcontroller. Depending on the direction selected on the touch screen, microcontroller controls the wheel chair directions. The joystick is to translate the movement of a plastic stick into an electronic information. Then it is processed through a controller. The speed controller works by varying the average voltage sent to the motor. This is done by switching the motors supply on and off very quickly using PWM technique. The methodology adopted is based on grouping a microcontroller with a touch screen.

The advancement of virtual reality technology offers various locomotion options that support users’ navigation behaviors in a virtual reality environment. This study was aimed at examining the effects of two navigation methods—joystick-controlling and walkingaround—on users’ perceived usability, behavioral engagement, and virtual presence. Fifty South Korean college students were recruited in the study, and they were assigned randomly to one of the two navigation conditions. Participants from each group were asked to observe a 3D object and complete the surveys. They were then asked to repeat the procedure with a 2D image. Using repeated-measures ANOVAs and MANOVA, we found that users using joystick-controlling reported higher usability and showed superior performance to the walking-around group on two tasks. Participants reported a higher behavioral engagement when observing the 2D image. Besides, they perceived a significantly higher virtual presence when observing the 2D image. F...

New development in sensors, radar and ultrasonic technologies has proved to be a boon for electronics travelling aids (ETAs). These devices are widely used by blind and physically challenged peoples. C5 laser cane, Mowat sensor, belt and binaural sonic aid, NAV guide cane are among popular electronic travelling aids used by blind peoples. For physically challenged person electric wheel chairs controlled by joystick, eye movement and voice recognition are also available but they have their own limitation in terms of operating complexity, noise environment and cost. Our paper proposes an automated innovative wheelchair controlled by neck position of person. It uses simple LEDs, photo sensor, motor and microcontroller to control the movement of wheelchair.

Super Atari Poetry is an interactive multiplayer poetry game-installation based on Atari 2600 consoles. It emphasizes the importance of cultural and historical values on game programming, showing the intrinsic relationship between natural language and machine language. Using the joysticks, players can create up to one thousand poems from verses that were previously written by the artist.

Power wheelchair joysticks have been used to control a mouse cursor on desktop computers, but they offer no integrated text entry solution, confining users to point-and-click or point-and-dwell with on-screen keyboards. But on-screen keyboards reduce useful screen real-estate, exacerbate the need for frequent window management, and impose a second focus of attention. By contrast, we present two integrated gestural text entry methods designed for use from power wheelchairs: one for joysticks and the other for touchpads. Both techniques are adaptations of EdgeWrite, originally a stylus-based unistroke method designed for people with tremor. In a preliminary study of 7 power wheelchair users, we found that touchpad EdgeWrite was faster than joystick WiVik, and joystick EdgeWrite was only slightly slower after minimal practice. These findings reflect "walk up and use"-ability and warrant further investigation into extended use.

Unmanned Aerial Vehicles (UAVs) are remotely piloted or self-piloted aircraft that are capable of flight without any on-board operator and can carry cameras, sensors, communications equipment or other payloads. UAVs have been used in a reconnaissance and intelligence-gathering role, including combat and rescue missions. This paper describes development and implementation of remote manual control system for a UAV. The paper includes design of manual control of air vehicle to achieve the desired target using a joystick and engine vibrations analysis. XBee-PRO 900 XSC OEM RF modules are used with extended-range, with 900 MHz embedded wireless system, providing end-point connectivity. The wireless transmitter and receiver pairs are used for data communication link between the ground station and the receiver on the vehicle. The manual control system is developed in a PC based system reducing the cost of overall system. Microsoft Visual Basic language is used for this control system.

An electric-powered wheelchair is a wheelchair that is propelled by means of an electric motor rather than manual power. Motorized wheelchairs are useful for those unable to propel a manual wheelchair. This wheelchair is used for patients with severe disabilities or life threatening diseases as well as for the elderly. To take care of different disabilities various wheelchairs with different electronic components have already been developed, such as wheelchairs having joystick control, head control etc. Many people with disabilities do not have the ability to control a powered wheel chair using the above mentioned interfaces. The proposed model is a possible alternative. In this project, we use an optical eye tracking system to control a motorized wheel chair. The camera continuously monitors the pupil and tracks it centre. When the pupil moves in a particular direction a corresponding signal is sent to the motor drivers and the wheelchair moves accordingly. When the user moves his eyes balls up the wheelchair moves forward, for left it moves left and right it moves right and in all other cases the wheel chair stops. The camera automatically calibrates the centre of the eye at the start of its working and decides the coordinates for left, right and forward movement accordingly. The rear wheels are connected to the motors and are responsible for movement of the chair. The front wheels are used to steer the wheelchair in the right direction.

In this paper we investigate the influence of the location of vibrotactile stimulation in triggering the response made using two handheld joysticks. In particular, we compare performance with stimuli delivered either using tactors placed on the palm or on the back of the hand and with attractive (move toward the vibration) or repulsive prompts (move away from the vibration). The experimental setup comprised two joysticks and two gloves, each equipped with four pager motors along the cardinal directions. In different blocks, fifty-three volunteers were asked to move the joysticks as fast as possible either towards or away with respect to the direction specified by a set of vibrating motors. Results indicate that participants performed better with attractive prompts (i.e. responses were faster and with fewer errors in conditions where participants were asked to move the joysticks in the direction of the felt vibration) and that the stimulation delivered on the back of the hand from the gloves gives better results than the stimulation on the palm delivered by the joysticks.

Background. This study applied EMG analysis methods to identify muscle group activity profiles and potential overload risks in powered wheelchair use.Methods. We quantified muscle effort and fatigue using EMG analysis methods during powered wheelchair manoeuvres by 10 multiple sclerosis patients. Video recordings of the different sub-tasks were related to information on surface EMG amplitude (rectified EMG) and spectral information (Median frequency) from M. trapezius, M. deltoideus (pars medius), M. deltoideus (pars anterior), M. pectoralis, M. biceps, M. triceps, wrist extensors and flexors, using Joint Analysis of EMG Spectrum and Amplitude (JASA analysis).Findings. Task durations and subjective data indicated that tasks requiring finer motor control took longer and were perceived as more difficult. Kinesiological functions of all muscle groups identified forward steering to be associated with activation of M. deltoideus (pars anterior), M. pectoralis, M. trapezius and M. deltoideus (pars medius); backwards steering with predominant activation of M. deltoideus (pars medius), M. biceps brachii and wrist flexors; left steering with maximal activation of M. biceps and wrist flexors, and right steering with maximal activation of M. triceps and wrist extensors. These profiles were confirmed in analysis of the functional tasks. JASA analysis documented muscle fatigue in the wrist extensors, whereas increased activation was found in M. trapezius, M. deltoideus (pars anterior) and wrist flexors.Interpretation. EMG based kinesiological analysis gives insight in muscle activity and fatigue during powered wheelchair manoeuvres.
