ergonomic

The words Ergonomic is take from Greek word “ergon” which mean work and “nomos” means natural law. Its mean that ergonomists study the relationship between human capability with work demands. Besides it also study of designing equipment and devices that fit with human body. It fit with movement and also its cognitive abilities. 


The purpose of ergonomic design is help to prevent strain injured and optimize human well-being and overall system performance by designed product such as safe furniture and easy-to-use interfaces to machines.   


Ergonomic draws on many disciplines in its study of humans and theirs environment which includes anthropometry, biomechanics, mechanical engineering, industrial engineering, industrial design, kinesiology , physiology and also psychology. In Europe and USA, they have their own society that about ergonomic. For example in UK is The Institute of Ergonomics and Human Factors  


According to International Ergonomics Association, there are 3 types of ergonomics which are physical ergonomic, cognitive ergonomics and organizational ergonomic. Besides according to the foundation of science of ergonomic that during the Hellenic civilization in 5th century BC, the citizen use the principle of ergonomic to create their tools, jobs and workplaces. And also this principle of ergonomic also used by Egyptians Dynasties to make tools, household equipment and  etc.

How to avoid the strains injured:
1)    Do not settle for a desk without a keyboard tray or some other way to set the keyboard height and angle correctly.  
2)     Do not place the keyboard on top of the desk.
3)     Do not place the monitor above your head.
4)    Do not sit in a rigid and upright position.
5)    Do not lean forward.
6)    Do not work for long periods of time without moving. You need to take frequent breaks. They keep you awake, productive and healthy and keep you from developing Deep Vein Thrombosis. At least once every hours then take should stand up, stretch muscles and move around
7)    incorrect lighting can result in neck or eye strain and shorten the time a worker is able to perform a task in this environment.
8)    Rest your eyes – at least 15 minutes then take break and look away from the screen for a minutes or two.
9)    Using ergonomic software. You can installed ergonomic software that will prompt you to take breaks. Some software even will suggest you some simple exercise that do in your workplaces.        


    Before buying ergonomic products, think the question such as:
•    Does the design and the manufacturer's claim make sense?
•    What research has the manufacturer done to support their claims?
•    Does it feel comfortable to use the product for long periods of time?   Sometimes it takes a little bit of time for a product to feel comfortable and "break in" or change your posture in order to become beneficial.
  •    If it hasn't' been recommended by an Ergonomist, don't use it.

What are the some syndrome of not using ergonomic product.
1)    Carpal Tunnel Syndrome – is a compression of median nerve in wrist. The symptoms are pain and numbness in hand especially at night, clumsiness, and trophic changes  such as muscle wasting. If you want to make sure whether you have Carpal Tunnel Syndrome or not, you can use Phalen’s test 


  Place the backs of both of your hands together and hold the wrists in forced flexion for a full minute. You should stop at once if you feel a sharp pain Occurs and then go to health care professional or use the effective conservative of Carpal Tunnel Syndrome are:
•    Chiropractic manipulation of the wrist, forearm and hand
•    Ice massage (10 to 12 minutes) several times a day
•    minimizing any irritating activities •    wrist strengthening exercises
•    wrist stretching exercises •    possible use of wrist brace or splint while sleeping
•    applying sound ergonomic principles

Scanners













·    Capture images from photographic prints, posters, magazine pages, and similar sources for computer editing and display
·       Come in hand-held, feed-in, and flatbed types
·       For scanning black-and-white only, or color.
·       Very high resolution scanners are used for scanning for high-resolution printing
·       Lower resolution scanners are adequate for capturing images for computer display
·       Scanners usually come with software, such as Adobe’s Photoshop product, that lets us resize and otherwise modify a captured image
·       Usually attach to our personal computer with a Small Computer System Interface (SCSI)
·       An application such as Photoshop uses the TWAIN program to read in the image
·       Some major manufacturers of scanners include: Epson, Hewlett-Packard, Microtek, and Relisys

TWAIN
§  Widely-used program that lets we scan an image (using a scanner) directly into the application (such as Photoshop)
§  Without TWAIN, would have to close an application that was open, open a special application to receive the image, and then move the image to the application where you wanted to work it
§  TWAIN driver runs between an application and the scanner hardware
§  TWAIN usually come as part of the software package we get when we buy a scanner
§  It also integrated into Photoshop and similar image manipulation programs


This video is to show how to clean your scanner


Lemur Input Device



-   Flat device that has a 12-inch multi-touch-sensitive LCD screen and an overall footprint the size of a large laptop. 
-   It contains its own processor for graphics and mathematics, so it uses no host CPU power.

-   An audio tool.






-   A highly-customizable multi-touch device.

-   Unlimited touch points.

-   From French company JazzMutant which serves as a controller for musical devices such as synthesizers and mixing consoles as well as for other media applications such as video performances. 

-   Creating an Interface

= Comes with its own proprietary software called the JazzEditor to create interfaces. 

= Users can build interfaces using a selection of 15 different objects (including fader, knobs, pads and sliders), group them as modules and arrange them using as many pages as needed. 

= Each object can then receive any MIDI or OSC attribute. 

= Particularity is the ability to modify the physical behavior of each object (for instance adding or removing friction on faders). 

= The internal memory of the Lemur enables the storage of many interfaces, each one controlling a specific software for instance.

-   Role is equivalent to that of a MIDI controller in a MIDI studio setup, except that the Lemur uses the Open Sound Control (OSC) protocol, a high-speed networking replacement for MIDI.

-   Low latency, higher data capacity, 32-bit numerical precision and easy set-up if compare to MIDI. 

-   Supported by an emerging number of applications, this protocol opens a new era in the field of real-time control and human-machine interfaces. 

-   A controller that thinks ahead and is able to adapt with the ever-changing landscape.

-   The controller is especially well-suited for use with Reaktor and Max/MSP, tools for building custom software synthesizers.

-   Enhance that precision, by zooming-in on any control. 

-  To save and navigate through all your interfaces with the touch of a button

-   Can tweak the 32 bands of a vocoder, control the most complex polyphonic granular synthesizer, or even generate crazy rhythmic patterns with the MultiSlider.

-   Integrate your lemur in a fast network

= Connect numerous computers and Lemurs on a local area network and make them all dance together.

= Faster data flow means seamless communication.

= The Lemur's fast Ethernet interface ensures a data flow hundreds of times faster than your average MIDI interface. 

= The Lemur has a built in 100BaseT interface, which means that the Lemur is capable of exchanging thousands of control messages at once with your application.

-   Complete the Picture

= JazzDaemon is a background application running on your host computer that handles MIDI communication between the Lemur and any number of MIDI applications or devices connected to your host computer. 

= This single interface allows you to control the track levels of your sequencer with one hand while playing your hardware sampler or virtual instrument with the other. Multi-tasking at its finest!

-   New Feature in details.
= Organized Container objects with tabs - Allow you to greatly improve interface layouts and ergonomics.
= Enhanced control of all your envelopes with the new Breakpoint object - Allows you to see exactly how you are changing the sound and you can easily add extra breakpoints with a simple double touch by offers total control of synthesizer or sampler envelopes with a multi-segment envelope editor.

= Faster set-up with the Alias feature - Duplicate a controller object that sends exactly the same information to your computer as the original with Alias. 

= Mouse and keyboard control - Lemur's objects can be used to remotely control the mouse cursor or computer keyboard.
= Acute precision with the new Gesture object - Emulates a track pad control with advanced gesture recognition and has three novel ways to interact with your sound. Pinch, rotate or trace your fingers to send different control messages to your computer.
= Intuitive design with new Lemur Menu object - It's a new pop-up menu selection tool offering a list of items from which to choose from.

= Easier interface design with JazzEditor.
= Extended scripting abilities - In the JazzEditor, a new Multiline script pane opens up a whole new world of possibilities. Any changes in your Live set are automatically reflected on the Lemur. 


Here is a video that show on Lemur Input Device =)








Manipulate buttons and knobs for some tasks or programs by using mouse nowadays are very troublesome and inconvenient. Somehow with the technology, there are many innovation that let us input conveniently such as multi touch by surface interface. The innovation of surface interface can be act as an input device which allows us to interact directly with the surface that we touch.

The Lemur input device is a hardware controller which applies the innovation of surface interface. It is a new development in music technology. By having Lemur input device as a control surface in live performance feels much more like playing an actual instrument than simple turning knobs or moving sliders. The Lemur also offers new method to communicate with the digital musical instruments which are not comprehended in physical hardware and allow for new creative possibilities.

How does touch-screen works...

Since our lecturer wants us to explore something does not discuss deeply in the blog, and she give us some ideas about the topic we can discuss. So, i would like to choose the topic' how does the touch-screen works? ' This is because i am interested in this topic and i got the experience to use the iPhone. I found that if i use my fingernail to touch the screen, i could not get the sensor. I need to use my fingertip to touch the sceen just can get the sensor.

Why You Can Only Touch With Your Finger

Most other touch screen devices allow the use of a stylus, or at least the touch screen can function when you touch it with something besides your finger. But with the iPhone, you have to touch the screen with your finger. This is because the iPhone can have a capacitor at every point on the screen only because each capacitor relies on feedback from the electricity in your finger to operate. When you touch the screen, the screen at that point senses the natural capacitance of your body (your body's ability to hold an electrical charge) and then registers a change in current at that point on the screen. If you use a stylus to touch the iPhone's screen or touch it with a gloved hand, the iPhone will not be able to pick up any natural capacitance and so it won't know you're touching it there.In reality, the iPhone has one half of a capacitor at every point on the screen. The other half of the capacitor is your finger. Together, the circuit beneath the glass cover and the capacitance in your finger change the electrical charge at that point on the screen.

I would like to discover more about the multi-touch in iPhone.

Each position on the iPhone's screen can independently pick up a touch. This means that you can touch the screen in more than one place at a time, and the iPhone will register all touches. Apple used this multi-touch feature in many of the applications and software on the phone. For example, when you are using a maps application or browsing your pictures on the phone, you can make a pinching motion on the surface of the screen and that gesture will zoom the image out. If you want to zoom in, you start with your fingers together on the screen's surface and then pull your fingers apart and watch as the application zooms in on where you first touched the screen.

If you want to know more about the topic, you may search from the web.


Since i found that the function of touch-screen in iPhone and iPod are almost similar, so i would also like to share about the infomation i found from Internet.
When you touch the screen, the iPod's circuitry detects the presence of your finger. It keeps track of how many fingers you have on the screen and where you move them. It also gives the iPod touch the capability of running apps. The iPod touch does this using a layer of capacitive material under a protective covering. You can read How Capacitors Work to learn more about them, but the basic idea involves taking advantage of the electrical properties of the human body. When you touch a capacitive surface, the amount of charge it holds changes. This is why devices like the iPod touch require you to touch them with your bare skin -- insulating materials like gloves, pens and styluses don't cause the same changes in the capacitive circuitry.
The basic process behind detecting touch


There are two possible methods the iPod touch can use to measure changes in electrical states:
  •  Self capacitance: Circuitry monitors changes in an array of electrodes. 

  • Mutual capacitance: A layer of driving lines carries current. A separate layer of sensing lines detects changes in the electrical charge when you place your finger on the screen. 
Regardless of which method the screen uses, you change the electrical properties of the screen every time you touch it. The iPod records this change as data, and it uses mathematical algorithms to translate the data into an understanding of where your fingers are.



After that i found another interesting question:


Why does ipad touch-screen work with fingernails but droid does not?

Both the iPad and Droid use capacitive touch screens, which work by sensing the disruption of the electric field at the surface of the screen by a conductive object (i.e. your finger). Neither of them should really work with a fingernail, as the nail isn't really conductive - I would guess that the reason the iPad picks up input from your fingernail is because its screen is more sensitive (probably because it is much larger), and therefore just having your finger near the screen (at a fingernail-length distance away) is enough to register without actually needing you to contact the surface.
