Final Board

Scenario of use:

This storyboard of the scenario of use displays how two friends begin their night with the wrist bands and due to excessive drinking one results needing to go home. It shows that the friends don't need to be together to use the Drunk Watch.

Final board identifying Scenario, Object and Behaviour:

Model Mock-Up

Blu tape and stanley knifes required to cut out strips.

Perspex was cut into the correct measurements and Blu tape was cut out and stuck on.

Pliers required to cut out strip of metal.

Strip of metal to be inserted between the the two perspex sheets (this provides the model with weight).

All are glued together using super glue.

All screen parts are glued together.

Bright yellow tabs were used in between a layer of perspex and the metal sheet so that colour appears on the 'Drunk Graph'. 

Fill-A-Gap was used to even out the surfaces.

Model with Fill-A-Gap on.

Spray paint was used over the entire model.

Each Blu tape strip was peeled back to reveal the yellow underneath.

Wristband was attached with super glue.

Buttons also attached using super glue.

Solid Works Renders

Green: I'm having fun!

Yellow: I don't feel 100%

Red: I want to go home

The 'Drunk Graph' on the front of the wristband screen is displayed whether there is interaction from the user or not. The colour that the graph is displayed in depends on the button that the user choses. So technically, the user could have reached the last bar on the graph and still be having a good night and it would then be displayed green.

How It Works

The Drunk Watch (Function)

What needs to be inside to make wireless work?
Needs a battery and circuit board. Battery will be very small- though larger then a watch battery as it is needed to charge all of the functions.
Watch strap buckle OR stretchy band?
Stretchy band. One size fits most. Easier to slide on and off then worry about a buckle especially if drunk.
Buttons? Connected to what inside?
The buttons will be individually connected by wires which connect to the circuit board. Connecting them to the circuit board allows the interaction to be received and then transmitted.
To receive messages via wireless what do you need?
Will need a transmitter and a receiver as the messages are going both ways. This is very similar to some of the technology used in mobile phones- it allows the two users to have plenty of distance between them, whereas bluetooth and GPS are often limited how far apart they can be.

Materials


For the band?
Must be stretchy, therefore, an elastic material would be ideal as it is able to stretch enough to slide over the hand to get on/off. A non-absorbing material would be favoured ie. plastic or rubber which is able to stretch. Absorbent material wouldn't be ideal incase a drink/water was spilled onto it and would be instantly absorbed.
For the screen display?
Plastic. Must be strong so the outside appearance doesn't become damaged and must keep al components   secure inside.
Lights? LED's?
Small LED's will be chosen for this design. Must only provide enough light to illuminate the 'Drunk Graph' and colour the buttons so that when in a nightclub (dark environment) the buttons are already illuminated and there is no confusion which one needs to be pressed.

Screen Design:

Blood Alcohol Level

Researching different options when detecting Blood Alcohol levels.

How Alcohol Affects Other Parts Of The Body

In addition to the brain, alcohol can affect other body tissues. It has the following effects on other systems in the body:

• Irritates the linings of the stomach and intestine - This can lead to vomiting.
• Increases blood flow to the stomach and intestines - This increases secretions by these organs, most notably stomach acid secretion.
• Increases blood flow to the skin - This causes a person to sweat and look flushed. The sweating causes body heat to be lost, and the person's body temperature may actually fall below normal.
• Reduces blood flow to muscles - This can lead to muscle aches, most notably when a person recovers from the alcohol (the "hangover").

Distribution

Alcohol has a high affinity for water and is therefore found in body tissues and fluids inasmuch as they contain water. Absorbed alcohol is rapidly carried throughout the body in the blood and once absorption of alcohol is complete an equilibrium occurs such that blood at all points in the system contains approximately the same concentration of alcohol.

Elimination

The liver is responsible for the elimination - through metabolism - of 95% of ingested alcohol from the body. The remainder of the alcohol is eliminated through excretion of alcohol in breath, urine, sweat, feces, milk and saliva. The body uses several different metabolic pathways in its oxidation of alcohol to acetaldehyde to acetic acid to carbon dioxide and water.

Main Points:
- Alcohol Increases blood flow to the skin. The sweating causes body heat to be lost, and the person's body temperature may actually fall below normal. (THIS means that there will be sweat there which could test the blood alcohol level on the user)
- Absorbed alcohol is carried all throughout the body in the blood stream. Once the alcohol has been fully absorbed, blood at all points in the system contains the same concentration of alcohol. (THIS means that measuring from the wrist will retrieve the same result as it would from another area of the body.)

This research means that I am able to assume it is possible to use sweat from a persons wrist to calculate their blood alcohol level at any particular time. This eliminate the need for the device to need to hang from the users neck as we no longer need to measure breath.


The wristband will have a sweat reader/detecter on the back of the screen face, which can absorb and calculate the blood to alcohol level from the sweat. 

Design Thinking

Product System:
- Connecting people and being aware of a distant situation
- Sense alcohol level and can work as a safety device
- Input and output that is somewhat controlled by the user
- Knows when friend is too drunk- they can do something about it
- Message from friend 1 that she thinks friend 2 has had too much to drink
- Consider- What is acceptable as a 'wearable device'?
- Consider- The amount of noise and darkness in clubs (interactions must address these aspects)

What the product still needs:
- A way to communicate to the friend to say i'm having fun (green), I don't feel very well (yellow), I want to go home (red).
- Could these be signified by a light display (green, yellow, red?)
- User must press one of three buttons to let friend know how they are feeling.

- New technology to read blood alcohol level through sweat, temperature or pulse?

- If not have breath detector on wristband (ie. small holes to blow into)

- Add a vibration when friend sends new message (makes you aware and you will look down to view the change) 

Brainstorming

I wasn't entirely happy with any of my ideas generated in class from the concept bombing. SO i did a quick brainstorm of ideas i think would be useful or work for this assignment:

Quick Ideas:

• Monitoring time spent in the shower (translate this to the mum/dad)
• Comforting messages (between couples)
• Monitor someones eating (health watch)
• Mood ring- detects partners mood (bluetooth, gps, wireless?)
• Connection when you receive mail
• Parking meter expire (gives you warning, lets you know)
• Dog barking monitor (lets the owner know)
• Health watch- zaps you when you about to eat bad food
• Doorbell to tell you who the person is
• Loosing a friend in a nightclub/festival (find them how?)
• Alcohol consumption competition- between friends on a night out- or couples who wants to know how much the other has had to drink. (you don't need to be together to know what level they are on- could it act as a safety device (you are aware if they're too drunk?
• Being able to tell who's at home before you get there?

Chose to extend my three favourite concepts.

Dog Barking Concept

General idea: A dog owner is worried her dog is barking throughout the day whilst she is at work. She needs to be constantly updated of when it barks, for how long and what times of the day.

Alert the owner: Via a gps bracelet which can vibrate or heat or become illuminated.

Vibration- Could become distracting

Light- Might not be obvious enough

Heat- Annoying on a hot day- however, it gets the message across.

(Quick scenario example)

Mood Band Concept

Need: A way to connect couples throughout days apart, it should signify how their day is going by the moods they go through. Moods to include- hungry, frustrated, angry, happy, tired, stressed,  bored, nervous, excited. * Meaning associated with mood jewellery comes from the temperature your body has *. Stone in the jewellery is either a hollow glass shell filled with thermotroptic liquid crystals.

How it works? My mood is displayed on my partners mood band. my mood band picks up my mood- transfers the info to my partners band and then shows my mood by presenting a colour.

Night-OUT Concept

Need: To connect friends who are in different places on a night out. Needs to add a fun-factor ie. can monitor the others drink consumption. Has an added safety feature (can see if a friend has had too much to drink and needs to be taken).

IDEALY this system can increase the fun you have on a night out. 

-Shows to friend drunk level

-Will have a breath testing device equipped in a necklace product so that when one friends is talking it can pick up their breath to alcohol ratio.

-This transmits via GPS to their friend and their 'drunk-level'

My favoured concept was the Nigh-Out concept and tutor feedback encouraged me to further develop this concept, however, making sure I focus the intent on the safety device side rather than the added fun feature. 

Stay posted to see how it goes!
