I am going to rate the Dingoo against Nielson’s 10 Heuristics. My son bought this little handheld game console so that he can play games from multiple systems in one handheld device (Arcade, NES, game boy, Atari, Sega, etc). It was a special order game device that shipped from China.
1. Visibility of system status
Feels very solid, not cheap. Turning on the game is a little strange. You have to slide a lever to the right and “hold” it until it comes on. When the screen lights up, you are ready to go.
2. Match between system and the real world
When the battery dies, and you try to turn the dingoo on the low battery comes on for such a short time it is hard to figure out what is wrong. All symbols are evident and the same as any other game system.
3. User control and freedom
Many buttons and controls like a Nintendo DS, menu like PS3 – very simple.
4. Consistency and standards
The buttons are in a different location than other handheld games but simple to pick up on the differences.
5. Error prevention
The sleep mode comes on too quickly – can’t fix. That’s all I could find for errors – no prevention. oops, I take it back, my son fixed it – with ease.
6. Recognition rather than recall
Even though you have to guess and press buttons, you eventually will figure it out – without breaking the Dingoo. Not exactly intuitive even for an avid gamer.
7. Flexibility and efficiency of use
You have to recall what buttons you pressed. For instance you have to hold down both “select” and “start” at the same time to end game and then scroll to “end” and push “A”. Do it once and remember forever, because if you forget or lose instructions, there would be know way of knowing this without trial and error.
Accelerators — Basic. If there are any new, I have not found them.
8. Aesthetic and minimalist design
The Dingoo is small and sleek and easy to hold. The screen is straight forward and easy to scroll through to find the game you want to play. Very solid little game.
9. Help users recognize, diagnose, and recover from errors
I have never come across an error message. You just have to keep pushing buttons to get around. Not entirely intuitive – but not necessarily annoying either.
10. Help and documentation
It came with a little instruction booklet in multiple languages. If it gets lost you can find more information on the Web.
Even though this rated poorly against some of the 10 Heuristics, I really like it and recommend it, this little thing comes preloaded with games, can play music, read e-books, connect to TV, play the radio and just about do everything. I give it five stars as entertainment for the bored.
