Voice Controlled Wheelchair Project Report

GUI of the android application have the facility to control the direction of the wheelchair and it has the provision to control electrical home appliances using radio frequency concept. System design uses IOIO board which contains a single MCU that acts as a USB host and interprets commands from an android application. Pin 31 and pin 33 of IOIO board are used as PWM output which is given to DC motor driver MD30C and pin 32 and pin 34 are used as direction control pins. Output of the DC drive is fed to two DC drive to move the wheelchair in different direction. For forward movement of the wheelchair both DC motor are rotated in forward direction.

MULTIMODE WHEELCHAIR WITH OBSTACLE DETECTION Ahlia Sultana Shaik, Anjana Subhash Menon, Binal Jayesh Tejani*, Mohammed Salih *email: be12022@waljat.net Abstract. The proposed idea of this paper is to design a cost effective motorized wheelchair which can help differently abled people. In this, an electric wheelchair is developed which can be controlled by finger gesture using flex sensors, or voice commands using an HM2007 speech recognition module. The user can switch between both as per his/her convenience. To ensure user’s safety, an obstacle detection feature using ultrasonic sensor is included.

Manual Opener Button Switch: The manual opener button switch is a supporting actor whose goal is to send a signal to the motor to open or close the door after receiving a signal from the home owner. b. Derive Use Cases Relevant to System Objective and Write Brief Description 1. UC-1 (Open Door): Open the garage door 2. UC-2 (Close Door): Close the garage door 3.

The phonemes are combined together to form words [1]. The speech recognition means transforming human speech to a text or to an order to the computer. The development of Continuous speech recognizers allows users to speak almost naturally, while the computer determines the content. It includes a great deal of "Co articulation", where adjacent words run together without pauses or any other apparent division between words. Continuous speech recognition work is difficult because they must utilize special methods to determine utterance boundaries.

Wheelchair transportation safety guide Session 20 Wheelchair Seating Systems for Use in Motor Vehicles For an individual who is unable to transfer to the vehicle seat, the wheelchair will be used as a seat for transportation. A wheelchair equipped with securement points as specified by ANSI/RESNA WC-19 and anchored with ANSI/RESNA WC-18 complied wheelchair tie-down and occupant restraint systems(WTORS) will reduce the risk of severe injury during the motor vehicle accident. A complete wheelchair seating system consists of a seat, back support & associated attachment hardware (e.g. head support) and postural support devices (e.g. pelvic belt anchorages, shoulder or upper torso belts).

The mechanical systems can be modeled with a suite of tools to specify bodies and their mass properties, possible motions, kinematic constraints, and coordinate systems. To get the dynamic model of the robot the following blocks related to CAD model are used. Revolute joint represents one rotational degree of freedom. The follower body rotates relative to the base body about a single rotational axis going through collected body coordinate system origins. Sensor actuator ports are added to the joint.

Certain practical implications of learning new and re-learning neural pathways will also be identified within the text. The yips, focal dystonia and the neurological cause of it will be explained. Finally there will be a discussion on how focal

Phone lines are used to transmit the signal to a central receiving system. The second type is a programmed contact device. A central computer at the probation office is programmed to call the probationer’s home at random hours to verify that they are home. They must answer the phone and insert their wrist transmitter into a device on the phone and their voices and signal transmission are verified by a computer. () Third is the cellular device.

Physical Therapist can identify these individual by locating them to these areas. These specific areas are real different. Orthopedic are those who work with injuries and disorder of the musculoskeletal system. Orthopedic is one of the area that is most accurate. Pediatric are those who work with babies, children, and teenagers on the mobile ability.

Figure 3, 4, 5 – Samples of Head-Mounted Display 2.2.2. Input Devices Any hardware device, that sends data to a computer is an input device. They allow users to control a computer and interact with it. They also determine the way in which users can communicate with a computer. Most popular input devices are: keyboards, mouse, digital cameras, joysticks, data suits and wired gloves.
