Ergonomics II

Ergonomics means laws of work, it is also the science of adapting the job and/or the equipment and the human to each other for optimal safety and productivity.

The five aspects of ergonomics are

1. Safety

2. Comfort

3. Ease of use

4. Productivity/performance

5. Aesthetics

The products

comfort:

the comfort shoes.

the comfort shoes are designed to provide comfort and cushioning for those who are on their feet all day, or are designed to relieve various kinds of foot pain.

safety:

handrails or grab bars in toilets.

the handrails or grab bars are designed to give support or balance.

ease of use:

samsung's jitterbug

they have large buttons and simple screens with large fonts are deigned to help the poor visioned elderly.

performance

It actually turns itself of when the elderlies fall asleep during a nap, while the remote has big buttons.

Ergonomics (Product description and Idea Trigger)

It is a ice-cream scooper that has a greenish colour and a metal thing that cuts the ice-cream away from the spoon.

It is supposed to be easy to use because most ice-creams stick to the spoon when it is being scooped up.

Yes, as the spring's tension is quite high so the elderly would have to use a lot of strength to push the trigger.

I thing we should reduce the tension of the spring and increase the length of the trigger.

Ergonomics I

Q.1 The work space of the first person is very stuffy, and the guy has to shift uncomfortably. Also, when he wants to lean back, he broke the chair he was sitting on. The lighting of his workspace was also bad as when he wants to shift a lamp, it is too hot and the other lamp is affecting the brightness of his screen. The guy also has neck aches from looking too much at the laptop screen.

The second person's workspace is spacious and his chair is also very comfortable. he can shift his body posture with ease and the hand support can also be shifted easily. His screen can also be shifted. He also have a laptop holder that he can use to look at the screen comfortably. The lamp he is using will not heat up easily, so he can shift it without burning his hands.

Q.2 The workspace that the second guy is working in is more preferred as it has a comfortable chair, spacious tables, adjustable lights that will not heat up easily, and a laptop holder that increases the height of the screen, with adjustable armrests that allow him to work comfortably.

Q.3 We need to look at his criteria and his "comfort level" to suit his needs, for example, the price, the type of armrests, and other factors affecting the person both physiologically, and physically.

Q.4 Because ergonomics affect the quality of their work and also their eagerness and stamina/strength to work.

Personal Reflection (8th Mar 2010)

i)

1)I learnt about ideas different groups are thinking, for example the chutes.....

2)I learnt that through surveys, we can get different ideas and plan our next step.

3)I learnt the ways to resolve problems through practical and creative ideas and we must not stick to our country, I also found out how lazy singaporeans are.

ii)

1)Is this effective for the current situation

2)Is the design feasible?

iii)

1)We can use multiple chutes instead of one whole chute to deposit our rubbish.

people(photography)

Everybody! there is a new armless entertainer in SST, class one-zero4! say hi as he waves at you. People are rushing to catch him on film. Hurry, while stocks last
Hi jeremy, poor thing...getting chased while posing for a camera.
gee, he sure is in a hurry and weird for..a person without arms

Photography

Types of photography: Animal photography, night photography, underwater photography and wedding photography

Equipment: Case, battery, stand, lenses, flash cover.

Aperture: It is an opening that controls the amount of light let in so the image can be captured on film

Focus: The distance from the surface of the lens to the focus point is called the focal length and is measured in milimeters. Most lenses are described by their focal length. Zoom lenses have a range of focal lengths, a feat which is accomplished by using a complex series of lenses which can be moved relative to each other. The mm number translates into a real distance, from the front of your lens to the chip of your camera. If an object is close to a lens, even several hundred meters away, its reflected light entering the lens isn’t perfectly parallel.

Shutter speed: The shutter speed refers to the amount of time that the shutter of the camera is open and the film is exposed to the light.

ISO speed: What ISO denotes is how sensitive the image sensor is to the amount of light present. The higher the ISO, the more sensitive the image sensor and therefore the possibility to take pictures in low-light situations.

Metering: Metering is a process which involves the camera taking a light level reading from the scene and selecting the appropriate combination of aperture and shutter speed to set the required exposure value.

White balance: The easiest way to describe white balance is by way of colour temperature which in itself is a way of measuring the quality and intensity of a light source. This is based on the ratio of blue and red light hitting the sensor, with the green light being ignored.

Composition (Rules): Rule of the thirds

The Rule of Thirds is based on the fact that the human eye is naturally drawn to a point about two-thirds up a page. Crop your photo so that the main subjects are located around one of the intersection points rather than in the center of the image.

Golden section rule

It has been found that certain points in a picture's composition automatically attract the viewer's attention. Similarly, many natural or man-made objects and scenes with certain proportions (whether by chance or by design) automatically please us.

Diagonal rule

One side of the picture is divided into two, and then each half is divided into three parts. The adjacent side is divided so that the lines connecting the resulting points form a diagonal frame.

Techniques: Read the instruction manual, check the batteries, know the focus zone, practice loading the film, understand backlight and frontlight, move in, get close, question the lab, understand the sunny f16 rule

Environment

from the web: All of the biotic and abiotic factors that act on an organism, population, or ecological community and influence its survival and development. Biotic factors include the organisms themselves, their food, and their interactions. Abiotic factors include such items as sunlight, soil, air, water, climate, and pollution. Organisms respond to changes in their environment by evolutionary adaptations in form and behavior. source: http://www.thefreedictionary.com/environment
the area in which something exists or lives; "the country--the flat agricultural surround"
source: http://www.wordreference.com/definition/Environment
That which environs or surrounds; surrounding conditions, influences, or forces, by which living forms are influenced and modified in their growth and development.

My thoughts: Our surroundings in which the factors that affect our survival

ADMT Lesson 1: Personal Reflection

1) It means art, desighn, media and technology, which is about desighning thing using infocomn.
2)They should be creative and also think out of the box...but must also be attentive and "steal" other peoples ideas
3)I would want to desighn innovative buildings, structures for the world to see that singaporeans have artistic talents too.
4)I must listen to the teacher attentively while doing my best in everything I do.
5)
Discription-the car has a sleepy driver as no media=no music and the driver is falling asleep with fatigue and also he is bored with no entertainment. the dove and the mailman signifies that there is no technology so there is no email and we must go by the traditional way. the people in the block has no TV, computer or mp3, etc. so they can only read books, th ebank note shows no desighn in a world with no desighn.

bottom: oblique, right top: orthographic

Orthographic projection is the arrangement of Plan, Side, Font or Back elevations on a 2 dimensional drawing. It shouldn't be confused with axonometric, which is a sketch with lines at 45 degrees to simulate a 3D view.

dimensional drawing. It shouldn't be confused with axonometric, which is a sketch with lines at 45 degrees to simulate a 3D view.

Isometric is a drawing method where horizontal lines are drawn at 30 degree instead, whilst vertical lines are always vertical. There is no vanishing point.

Perspective drawing, source:http://jhh.blogs.com/anthos/2006/01/add_windows_to_.html?cid=140620118

Orthographic projections are drawn to a vanishing point while Isometric projections are not and are also based on a 3 120 degree axis.
