The shuriken prototype that I made was based on the persona of an individual who was passionate about Japanese culture – specifically the time period of samurai’s and ninjas.
I hypothesized that my Shuriken prototype would resemble a real Shuriken in multiple facets such as sharpness, durability, concealability but primarily by its visual aesthetics. To confirm my hypothesis I asked users if they believed my Shuriken was equivalent to a Shuriken artifact, to which 100% of users suggested that it did resemble an actual Shuriken.
I chose to ask eight questions to 11 users. The IEC standard for Usability mentions that you only need 5-8 users to come to a conclusion. Therefore, I chose 3 extra users to confirm my conclusion. I made sure to ask a small amount of impactful questions, so that users had time to think and respond to the questions without thinking about its sheer volume. Table 1 is a summary of the survey.

- Survey Questions and Outcome
Question
Outcome
Are you aware of what a Shuriken is?
90.9% said yes, 9.1% said no.
If yes, does my design visually
represent an actual Shuriken?
100% said yes
If you held the prototype, did you think
the Shuriken edges were sharp? If yes,
please rate the sharpness from 1-5.
81.8% said yes (4 or 5) and 18.2% said they were
indifferent (3)
Do you think the Shuriken can be
hidden in your pocket?
54.5% said yes and 45.5% said no
How do you rate the material of the
Shuriken?
90.9% said it was durable and 9.1% said it they were
indifferent
Please rate the ease of instructions on
a scale of 1 to 5
63.6% said it was super easy to use while 36.4% said it
was fairly easy to use.
If you rated the question above difficult
to read, what would you change about
it?
One individual commented that they would like to have
a storage compartment for this Shuriken when not in
use.
Do you think there are specific features
that would make my prototype better?
One individual said they would like to see many sizes of
the same product.
One individual said they wanted more safety guards.
One individual suggested testing all the grips.
The survey results indicate that the shuriken prototype closely resembles a real shuriken in terms of its visual aesthetics. The majority of survey respondents rated the shuriken highly in terms of its sharpness and durability, indicating that the prototype is well-
designed for its intended purpose.
However, there were some areas of concern and opportunities for improvement that were identified by survey respondents. For example, some respondents suggested that the shuriken prototype could be improved by offering it in different sizes, as this would allow for

greater versatility in its use. This product was designed in 3 different sizes, however, only the final iteration was shown within the survey. In the future, I will also show the sizing options as images within the survey. The images will include a scale at the bottom for reference. Additionally, some respondents suggested adding safety guards to the shuriken in order to reduce the risk of injury. This could be done by adding rubber guards on the shuriken itself.
Another area for improvement identified by survey respondents was the grip of the shuriken. I can design different grip designs and conduct user testing to identify the most comfortable and effective option for users.
Finally, some users suggested adding a storage compartment to the shuriken when not in use, as this would make it easier to transport and store safely with child lock features.
Overall, the results of the survey suggest that the shuriken prototype is a promising design for a real shuriken. However, further research and development may be needed to address the areas of concern identified by survey respondents and to refine the design to ensure optimal performance and usability.
