These are the most important concepts to our product. 1 is highest priority 5 is lowest, but it does not mean that they are
- The helmet must act like a helmet, and still must protect the head.
- The lights must indicate well enough to inform the drivers and pedestrians. If the drivers do not see the blink light he would not brake down and therefore it is important that these lights must be easy to see and understand.
- The using the electronic parts of the helmet not be annoying or hard for the user. Making the electronic parts in the helmet easy to understand and use.
- The sound horn must be able to alert pedestrians but also the user cannot be annoyed whilst using sound horn.
- The helmet should be comfortable to wear for extended periods of time. About 30 minutes.
Test 1. The helmet must act like a helmet, and still must protect the head witch it dose we have done some impact tests while a user was wearing the helmet they said it protects well and the cables and such inside the helmet dose not damage the user on impacts.
Test 2. The lights must indicate well enough to inform the drivers and pedestrians. If the drivers do not see the blink light, he would not slow down and therefore it is important that these lights must be easy to see and understand. To Test this we had a Tester use the helmet while riding a E-scooter and one of us in a car to see if we noticed the signal light too the right witch we did but it was a little hard to see so we need to switch to brighter and stronger lights so they work also in daylight since they are only visible in the later time of the day when it is dark outside. And since the signal lights are on auto, we need to setup a button or motion system so the users can turn the lights on or off in the direction they are going.
Test 3. The helmet should be comfortable to wear for extended periods of time. About 30 minutes. This test was easy to get information on because we and the users did wear the helmets for a extended period 10-15 minutes and noticed that the helmet is a little small and uncomfortable so we need to add a feature to tighten or loosen the helmet around the head and a bigger chin wrap.
How should these be tested?
- We would have to conduct some sort of user test with users. We should make a stress test and a test in functionality. The first part would be an interview to see if the users look at this helmet as safe or not from the first glance. This is to check what the users first impressions are. First impressions are always important, if the user does not feel comfortable from the start it is not likely that the user will use the product.
- The second test should be a user test in functionality where we give clear instructions in what they must achieve but not explain how. After they feel like they completed the tasks we interview them where we ask how they did the task, why and did they feel like the helmet worked for the purpose. This is the test where we get the answers to our concepts.
We got 3 students that were willing to take the interviews and the test, they have not seen the helmet before and they do not know what to expect, just that they will test a helmet for functionality and safety.
Testers: Tor, Martin, Ingrid
Pros with the helmet
- Does light up and make it safer with the lights if functioning properly
- The Sound horn does make sense and gives a good auditory warning if a scooter rider has the helmet on and chooses to use it.
- The blinker lights work as a concept and will help to inform the drivers that the user will cross the road.
- Break lights informed pedestrians and drivers that the scooter is breaking down
- The headlight works as intended but should change the color from green to white.
- The helmet has shock proof padding, so it can protect the users head if hit in a collision.
Cons with the helmet
- The horn sound is annoying for the user
- Blinker lights did not have a button to toggle them on or off
- The driving light is green, not a great color to light up your surroundings
- Must run on a power bank
- Make the sound horn have a better sound that alerts people better without being annoying to the user. We can also mask the sound from the inside of the helmet, so the sound is not as sharp for the user of the helmet
- We will have to make either a button or some other function to turn on and off blink lights/turn lights
- Change out the helmet driving lights to white. So, the helmet could light dark spaces like asphalt better.
- We should also change the way the helmet is powered. Batteries could be a better alternative since it more convenient than the power bank, or even better have both alternatives available than just a power bank.
Testing: Tor, 21
Keep in mind that we tested our user with the first prototype we had so we had to make questions about our prototype
The first glance
Tor is a student at HIOF in his first year. He is taking a bachelor’s in informatics. He is 21 years old. When he first saw the helmet, he chuckled and said that it was funny looking. Then he picked it up and examined it. he looked at the sides of the helmet and inside and said that the electronics looks crude. We asked why it looked crude and he answered because the cables go everywhere, they are taped together with duct tape. Then we asked Tor if the helmet looked save if used in a normal environment and asked him to clarify for us, and he did say yes since it is still a helmet and a bright one at that, which would help people notice that an e-scooter rider is driving along.
After that we asked Tor to turn on the helmet. He did just that and his first reaction was laughter. We asked him why he was laughing, and he answered because the helmet as a concept was ridiculous. We asked Tor if he had the option to use such a helmet would he use it and why. He did say yes, because he liked the helmet and he liked the idea of how he could use blinkers to indicate where he was going to drivers without effort.
What how why, The test:
We asked Tor put on the helmet and turn it on. When the helmet was on Tor, we asked him to ride a couple laps around HIOF to check the helmet comfort, and to see if drivers and pedestrians could see the blink lights and break lights. Keep in mind that the prototype we are testing does not have every feature we intended such as buttons to turn off and, on the blinkers, since we don’t have a button to activate or deactivate the lights. The same goes for the sound horn and the brake light. Since the prototype was so primitive, we had to test the visibility and the utility of the blinkers. We tested the lights in a scenario where they would be used. So Tor took a sharp left turn and we checked to see if the helmet actually indicated that he was going left. The light was certainly strong enough to see that there was an orange
blinking light. However, for some drivers this could be seen as nothing, so to further indicate that the blinkers actually are blinkers, we should increase either the size or the amount of the orange LED lights. The brake light was understandable, but we could also increase the size of the light, so the LED light could have a better range.
The user said that helmet was comfortable, at least when he used it and did not see a problem with wearing the helmet in longer periods of time. When the user had the helmet on, we tested out the features we implemented. The user did not see the blink lights, or the break light. He did however see the front light, though he said that the lights were a little high up and therefore did not illuminate the ground. When Tor heard the sound horn, he said that the sound was loud and annoying, specially to him because it was right on top of his head. We did not ask a random driver to see if the blink lights worked, but we did have one in our group go to his car and see if he would react to someone turning a corner with the helmets blink lights and see if him, an average driver could react and respond to it. that to which he could.
Finally, the sound horn did make a loud enough sound for the pedestrians to hear and to be reacted by, but keep in mind that the sound horn is loud for the user of the helmet. The helmet safety and sturdiness were also tested by hitting the helmet with the tester knuckles a couple of times. Since the helmet withstood the hits, we assume that the helmet is safe for use. The front light was also a little high up according to Tor.
In conclusion for the interview and test with anonymous participant Tor, we must make the blink lights bigger or wider to increase the visibility. The same goes for the break light. We must put the front lights a little lower and change the color from green to white. We must dampen the sound horn sound for the user of the helmet. Add buttons to the lights so the helmet can have real functioning lights, and finally add some alternative power sources to the helmet so it will not rely on a power bank alone.
Testing: Martin, 24
Martin is a typical student at HIOF which lives about 2 km from the school. He is really into new electrical transportation devises, but not limited only to the e-scooters.
His first impressions was surprisingly positive. He said it wasn’t really a pretty sight, but after all it is a prototype and it has a lot of potential.
We conducted the same testing as before with Tor. Martin’s feedback from the test-results didn’t differ too much from Tors. Martin also found it comfortable, the lights worked and gave him much more visibility for his surroundings.
These test results pretty much gives the same conclusion as stated above. The blinkers need to be wider and the front light bigger. Either add buttons to control the blinkers or even better; a rather technical, but totally doable gyroscopic solution where he could bend his head the direction he wanted to blink.
Testing: Ingrid 21
The first glance
She looked at the helmed and laughed because of the color and how it looked with the lights and how it looks inside with all the cables that are taped together and are covered with just some shock pillows that were inside the helmet from when we bought it.
What how why, The test:
We asked Ingrid to take ride around HIOF to check the comfort of the helmet and if other people such as pedestrians and drivers could see her easily with the back light front light and signal lights. The front and back lights are visible but it can be hard to see the signal lights if its not dark outside so we will need to get some stronger and brighter lights and program and hook up some buttons to control the lights on the helmet since now the helmet is very primitive so the signal lights go in a loop and the back and front lights just stay light up with no other motion like the back light getting brighter when you break with the e-scooter.
The user said the helmet was a bit tight and the chin wrap was too little for comfort so we should make the helmets chin wrap and size more adjustable so it is more one size fits all so its not like the helmet only fits a couple of people and restrict the market and safety of users who would want a helmet like this. Lights where a little weak such as the signal lights but all lights all around should maybe get an upgrade some reflexes would also make an improvement for pedestrians and drivers to spot an e-scooter rider easier in both day and night light. The horn is annoying and will at least need an button for control and a much stronger sound because now the only one who can hear it is the user of the helmet just maybe scrap the horn all around since it can obscure the users sense of what is around them like if a car is coming around a corner that the user cannot hear because of the horn.
These tests have given us the same info from the three that have conducted the tests that the lights are too weak and need buttons, the helmet is small for some and fits right for others so some kind of adjustable chin straps and head strap would make it better for all users so it can fit their head form. And the lights need to become brighter and stronger so they work in daylight and nighttime also change the green light in front to a white light that can light up the road, so it works more as a driving light.
