Smart Wheelchair For Better and Easy Life ( Human Factor 3rd Assignment )

Smart wheelchair with brain signal recognize for totally paralyzed persons.




A smart wheelchair, or autonomous wheelchair, typically consists of either a standard powered wheelchair to which a computer and a collection of sensors has been added or a mobile robot base to which a seat has been attached. The typical control system used by smart wheelchairs, based on the use of a joystick,is not suitable for totally paralyzed persons.Millions of people in the world suffer from several diseases (e.g., amyotrophic lateral sclerosis ― ALS, multiple sclerosis, cerebral paralysis, spinal cord injury) that destroy the neuromuscular channels used by the brain to communicate and control body movements. This calls for the development of a flex-ible system, able to adapt also to the necessity of completely locked-in individuals. So challenging an objective can be achieved by a system able to determine user’s intentions through the analysis of his/her cerebral signals and to transmit this information to an external device, such as a wheelchair. This system is called brain-computer interface(BCI).

There are several methods to acquire the cerebral signals; among them, I choose to consider the electroencephalogram (EEG) because of the advantages that it brings in terms of non invasivity, practicality, safety and low cost. Electroencephalography (EEG) has emerged as a promising way for paralyzed patients to control computers or wheelchairs. But EEG has limited accuracy and can only detect a few different commands.

How incredible would it be for a person who can't move their arms or legs to be able to literally think their way around a room, avoiding obstacles and getting where they want to go with mind-power. A new wheelchair created combines brain messages with artificial intelligence to give hope for independent mobility to paralyzed people.

This is sample design of smart wheelchair using brain messages recognize.



To work the chair, brain signals such as imagining moving your right arm to go right or your left arm to go left, are sent to the chair as commands, and the chair combines the commands with artificial intelligence and data from two webcams installed on its sides to maneuver around things like chairs, tables and other obstacles. Perhaps what is even more amazing, is the user needs only a few hours of training per day over the course of a week to master using the chair.

Design The Fool Proof Power Button of Remote Control ( Human Factors Class Assignment 2 )

Design power button for decreasing human error.

We must concern about the shape and the place of power button, because it is very important for human to makes mistakes to press the button. So the purposed to decrease product defects by preventing, evaluating, or design attention to human errors.
Power button can be design with a voice recognize sensor or to turn off and turn on the LCD we can use signal sensor to detect what cable plug in the LCD, if have some cable connect in the LCD, that's sensor will check the signal what of kind of signal, if that's signal is RGB,Video or HDMI signal so LCD will turn on automatically. So if that's cable unplug in the LCD will standby until 1 minute after 1 minute don't have cable again plugin, LCD will turn off automatically and completely.
And also with voice recognize user can say's some word to turn on the LCD, for example say's "LCD ON" and LCD will turn ON automatically and say's "LCD OFF" to turn off the LCD.

So in my design have two way to turn on and turn off the LCD. First is with signal sensor inside the LCD, second with voice recognize sensor in remote control of LCD. that is prototype of my design.

"Perfect Peeler for Better Life" (Human Factors Class Assignment)

2011-09-28 08:48:50 | 日記




A peeler is a metal blade attached to a wooden, metal or plastic handle that is used to remove the outer skin or peel thus peeling certain vegetables, frequently potatoes, and fruits such as apples, pears, carrot and many more. The second variety more closely resembles a safety razor (sometimes it is called a Y-peeler (due to its shape), Rex peeler, yoke peeler, or speed peeler), with the blade perpendicular to the handle, is used with a similar action to a razor, shaving off skin in strips parallel to the handle. Most speed peelers have an 'eye gouger' beside the blade, a loop of metal used to dig out eyes and blemishes from the potato.
In the stores and many market we will find many models of peeler, one of them is a product from Kyocera. Perfect peelers is Original design from Kyocera,this peeler is very ergonomic, because head of the peeler can rotation vertical and horizontal until 45 degree so make it move easier than ordinary peeler also can use with right or left hand. With ABS resin make peelers handle not easy to slip and blade easy to wash because it is made from ultra-sharp advanced ceramic blade.
