I am going to describe about the usability of the mobile phone "Nokia-N Gage QD" .The N-Gage QD is the one of Nokias original gaming mobile phones. It is a smart phone using the Symbian 6.0 Operating System, which is found on many other Nokia mobile phones.
GOOD AND BAD ABOUT THIS DEVICE FROM MY FIRST IMPRESSION
From my first impression, I thought this mobile was designed for gaming only. So this mobile should be very handy for playing games. It has a large display, so it will be easy to read messages. This mobile has an option of expandable memory, so it will be helpful for me store more data in the phone. This mobile has a rubber band which covers the oval shaped body. This will avoid damage to its important components in case if it falls down. It has high volume sound which is helpful during travel because the ring tone of the incoming call would be highly audible.
Even though it is handy for playing games in my first impression, it looks little thick and big in size. It has lot of keys, so it is difficult for me to remember all the keys. It is oval in shape, not rectangular or square, so this mobile does not fit in my hand comfortably. It does not have a camera, and so I cannot take photos using this mobile. This mobile has key pads on both sides of the display and it requires both my hands to perform some basic tasks. This makes it difficult to use the phone in situations, such as in bus travel, where it is impossible for me to use both hands simultaneously.
DESCRIPTION OF USER EXPERIENCE AFTER INTERCTING WITH THIS DEVICE
Based on my experience this device suits only for playing game, because the key pad is separated from the direction pad. The left hand side key pad is useful for control directions, and right hand side key pad is useful for performing other functions. If I install MP3 player software I can hear songs with much better clarity. The phone's multi task function allows me to use the messaging option while I am hearing songs. The stand by time of the phone is not so good. If music or games are played for a few hours, the phone charge gets drained immediately. In certain situations, like when travelling in bus, or riding a bike, it is not easy to retrieve the phone from the pocket because of its huge size. It is also very hard and irritating to message in these situations, since messaging requires the use of both hands. The phone has Bluetooth, but no Infrared. This makes it difficult to transfer data to phones that only have Infrared. And if the amount stored in the phone is large, it makes the phone very sluggish.
Sometimes my grandfather uses this mobile to make his calls. He has a condition of blurred central vision in his right eye. He has difficulty in pressing the intended number, since all the numbers are close together, and he is has tremor in his hands.
One day my father used this mobile for his business calls. This mobile also has internet browsing facilities. He found difficulty in checking mails and making video calls, because this mobile is not having any short cut keys for internet, and does not have 3G technologies for video calling.
My younger sister frequently uses this mobile for playing games. She has long fingernails, and since the key pad has gloss finish and is quite congested, she finds it difficult to play games and often she press wrong button.
From my experience this mobile does not suit well for people of old age and for business people.
