Spring Term Studio 1: Background to paper prototyping

Blackberry Messenger Interface:

I will be prototyping the blackberry messenger service , this messaging system allows communication , between different blackberry devices through a identification service known as a blackberry pin here’s an example of the blackberry identification : BB pin 26BCDE5E

(a)          How can prototyping digital technology with paper be justified?

(b)         How do you make a paper prototype?

To make a paper prototype you use rough ideas and a simple layout of the device being used 

          (c)       How do you design and run a usability study around a paper prototype?
by making it as interactive as possible , the aim of the paper prototype is to show early interaction of a device , for example as a user clicks on a button the tester can simply give the test user a paper that shows the next step of the process.

THE REALLY RUBBISH INTERACTION CHALLENGE

THE REALLY RUBBISH INTERACTION (RRI) CHALLENGE

1)Tesco Self-Checkout system

DESCRIPTION

An example of a rubbish interaction is the Tesco Self-checkout system , when you attempt to buy a item for example a pack of tangy haribo and you want to cancel it the screen automatically displays a message on the screen and blocks all functions of the system , the message displayed is “ please wait for staff Assistance “

PICTURE/Technology

WHERE IDENTIFIED, and HOW OFTEN

I identified this problem in TESCO 24 hours Supermarket, Lewisham, London – this problem has happened on so many occasions in the last two years , as I visit Tesco regularly.

WHY IT IS RUBBISH

The task – the task is to cancel items scanned on the system

The conceptual Frameworks - Usability in life : this system should work every day as it is needed for the supermarket to run smoothly

Satisfaction :

WHY THE RRI (REALLY RUBBISH INTERACTION) SLIPPED THROUGH THE NET

I believe the issue at hand was not identified because Tesco tested the product to meet the minimal objectives only .

WHAT'S THE SOLUTION?

1)Design change

system should be revised to allow a faster transaction for customers when shopping at tesco , as the problems slows down the whole shopping process. i believe their  should input a ask for staff assistance button which signals if the customer needs help so it will be at the customers own accord.

or maybe thoroughly revamped the systems to ensure the error doesn't come up every time a customer wants to cancel a item.

2)Usability test

to test if the system is thoroughly effective by making multiple testers try different  functions each time for example one user could test it by buying a product using a debit card , and another user try by using cash .  

2) Oyster card top-up system machine  

DESCRIPTION

An example of a rubbish interaction is the Elverson road ,when you attempt to buy or top up an existing oyster card , sometimes the screen is affected by the sunlight and the screen is almost impossible to read , leading you to move your face directly into the screen to read.

WHERE IDENTIFIED, and HOW OFTEN

i identified the problem at Elverson road DLR station , this problem has happened on so many occasions in the last year , as I Travel regularly.

WHY IT IS RUBBISH

The task – the task is to successfully top-up an oyster card. 

The conceptual Frameworks - Usability in life : the screen needs to visible as users need to be able see

Satisfaction :

WHY THE RRI (REALLY RUBBISH INTERACTION) SLIPPED THROUGH THE NET

I believe the issue at hand was not identified because TFL tested the product to meet the main objectives.


WHAT'S THE SOLUTION?

1)Design change


the system doesn't need to revised , however the physical design needs revised , by adding a type of screen protector 

2)Usability test

to test if the system is thoroughly effective by making multiple testers try different  functions each time for example one user could test it by buying a product using a debit card , and another user try by using cash . 

to test the physical shape of the top-up system , allow multiple users to test the machine in distracting sunlight.

3) oyster card top up services
