Part 2-Fender Guitar Auto Tuner

A. What can I tell about the product from first impression?
1.First impression good-small, very portable, convenient to always have a tuner, a good brand, I know
what it is.
2.First impression bad-very limited display display to tell the user at what degree the guitar is tuned to, looks cheap

B.A description of the user experience resulting from interaction.
1.Pros: portability, convenient
2.Cons: lack of accuracy, limited interface

C. Compile a set of usability and user experience goals most relevant in evaluating the device. Which are the most important and why?
1. Portability-A tuner small enough so that a guitar player can carry it with him at all times.
2. Ease of use-The tuner should be very user friendly. The tuner should save time for people when they tune their guitars.
3. Accuracy and consistency-It is very important for the tuner to be accurate or the guitar may soundoff key.
More importantly   it needs to be consistent about its tuning. Or else it would make it hard
for when more than one person is using the same tuner, because they will all be slightly off from each other.
4. Durability-Many people who plays music travels a lot. It is important to design to tuner to
withstand a certain amount of physical abuse.
5. Sustainability- It should be energy friendly. The guitar player shouldn’t have to spend more time
to maintain a tuner than his guitar.

D. Translate each of your set of usability and user experience goals into 2 or 3 questions and apply to your device to see how it fares.
1. How portable and convenient is it? – You can put it in your pocket and have it on you at all times.
2. Is it a good tuner?-It gets gets the job done, but you can still hear the difference in tuning quality
comparing it to a rack tuner.
3. Is it easy to use?-It is very easy to use. It only has a on and off button. The rest is all shown by the
LED lights.
4. Is it durable?-It is fairly durable. I have dropped it multiple times. It still works.
5. Is is energy friendly?-The battery lasts pretty long.
6. Does the interface of the tuner provide enough help when people tune their guitar?-It gives the
user just enough information to know whether he or she is tuning the guitar to the right note. It
lacks the display that can show precision tuning.
7. Is it consistent with its tuning?-It is hard to tell. It only tell the user when they hit the right
notes. Therefore it has a larger deviation for tuning of one notes, or else it would be way too hard
for the user to tune the guitar.
8. How will inconsistency affect user experience?-It may cause the user to stop using the tuner.
Because the tuner only has one function, it loses its value if it can’t serves that function correctly.
9. What would happen if the tuner is not very durable?-It get broken really fast, because people like
travel with the tuner and pass them around a lot.

F.Discuss possible improvements
1.The display on the top left could be changed for more precised tuning. Rather than just having
whole step and half step interval tuning, it should also have a quarter of a step interval
2.There should be a output jack on the tuner. This way the user can be plugged into the tuner while
3. A LED battery level indicator should be placed on the back. It would flash when the battery is low.
This way the user will know when to get a new battery for the tuner ahead of times.
4. A clip should be placed on the back of the tuner so the user can clip the tuner to his belt of the
strap when he is not using it, or when his is running is guitar through the tuner to the amp.
