Week 1 - CAD Something

Options for final project:

• ShareableWearable - a wrist or chest worn projector that uses a small muscle movement (spiderman hand gesture?) to live project whatever you’re viewing on your phone or smart glasses
• BrainJam - Galvanic vestibular stimulation plus music headworn wearable
• oobTube - a bed/tube to incite out of body and other mystical experiences through full sensory stimulation (visual, audio, vestibular, somatosensory, haptic, etc.)

Thoughts on options

oobTube:

• good
• large budget (hundreds of $)
• supporting evidence?

BrainJam:

• Good!
• Lots of mechanical design for aesthetics + comfort.
• Bad - not big

Shareable Wearable:

• better as a hack than a large project maybe?
• more time messing with projection tech than on design and fab, so less good

Winner

BrainJam sounds best for now

Mechanical requirements

• Electrodes contact - 4 electrodes. 2 on the mastoid, 2 on the forehead.
• Stay on head - It also needs some reasonable support, as it will be worn at music events and by dancers, who will move a lot.
• Physical comfort - needs to feel good on head for hours of use. Should forget you’re wearing it.
  • light weight
  • even weight distribution
  • no irritating connection with skin (hot, sweaty, itchy)
• Aesthetic / Social Comfort - Otherwise, I want it to look nice. I started by asking GPT4 to give me some good midjourney prompts to generate images of a wearable that meet my needs. Here’s my GPT4 prompt:

                    I'm trying to generate an image with midjourney. Help me make a good prompt. Feel free to give me multiple different prompts to try.

                    I want to generate an image of a wireless galvanic vestibular stimulation headworn wearable. I need electrodes on the two mastoids and on the left and right forehead, so 4 total. I want the wearable to be natural looking, chill, unoticeable, cool, and socially acceptable and physically comfortable.

GPT4 Response:

Creating a good prompt for image generation requires clarity and specificity. Here are several prompts you can try for generating an image of a wireless galvanic vestibular stimulation headworn wearable:

                    1.

                    Design a sleek and modern wireless galvanic vestibular stimulation wearable. It should have electrodes placed discreetly on the two mastoids and on the left and right forehead. The design should be natural-looking, blending seamlessly with the wearer's head, ensuring both physical comfort and social acceptability. Aim for a chill and cool aesthetic that would be unnoticed in everyday settings.


                    2.

                    Imagine a world where headworn wearables are as common as sunglasses. In this world, create a wireless galvanic vestibular stimulation device with electrodes on the two mastoids and both sides of the forehead. It should be so stylish and comfortable that people would want to wear it not just for its function but also as a fashion statement. The design should be chill, unnoticeable, and socially accepted.


                    3.

                    Craft a wireless galvanic vestibular stimulation headworn wearable that looks like it belongs in a high-end tech store. It should have electrodes subtly integrated on the two mastoids and on the left and right forehead. The overall look should be so natural and cool that someone might mistake it for a regular accessory. Comfort and social acceptability are paramount.


                    4.

                    Envision a headworn wearable for wireless galvanic vestibular stimulation that one might find in a futuristic fashion magazine. With electrodes cleverly positioned on the two mastoids and both sides of the forehead, the design should be so chill and unnoticeable that it becomes a trendsetter. It should prioritize wearer's comfort and social acceptance.


                    5.

                    Create a wireless galvanic vestibular stimulation wearable that could be worn at a cafe, a party, or a business meeting without drawing attention. The electrodes should be placed on the two mastoids and on the left and right forehead, but they should blend seamlessly into the design. The wearable should exude a chill and cool vibe, ensuring the wearer feels both physically comfortable and socially confident.


                    You can use any of these prompts as a starting point and adjust them based on the specifics you want to emphasize or the style you're aiming for.

Images:

What I learned from these images:

• cover the top of the head looks bad
• black > white
• no lights on outside
• since we don’t need a connector in the middle of the forehead, the device should only extend to just past the hairline, to be less obtrusive
• cover the least amount of area of skin/head as possible
  • better to cover the back of the head if needed

Next GPT4 prompt (in same context window as prompt above):

Ok those, looked really good. Here are my notes:

                    What I learned from these images:

                    - cover the top of the head looks bad
                    - black > white
                    - no lights on outside
                    - since we don't need a connector in the middle of the forehead, the device should only extend to just past the hairline, to be less obtrusive
                    - cover the least amount of area of skin/head as possible
                        - better to cover the back of the head if needed

GPT4 response:

Given your feedback, let's refine the prompts to better match your vision for the wireless galvanic vestibular stimulation wearable:

                    1.

                    Design a sleek wireless galvanic vestibular stimulation wearable in a discreet black finish. The electrodes should be subtly placed on the two mastoids and on the left and right forehead, extending only just past the hairline. Avoid any lights on the exterior and ensure the design is as minimalistic as possible, covering the least amount of skin or head area. If additional coverage is needed, prioritize the back of the head.


                    2.

                    Imagine a minimalist and stylish black headworn wearable for wireless galvanic vestibular stimulation. The electrodes should be seamlessly integrated on the two mastoids and both sides of the forehead, without extending too far forward beyond the hairline. The design should be free of external lights and should prioritize covering the least amount of the wearer's head, with a preference for the back if necessary.


                    3.

                    Craft a wireless galvanic vestibular stimulation headworn wearable that embodies the essence of discretion. With a chic black finish, the electrodes should be positioned on the two mastoids and the left and right forehead, stopping just beyond the hairline. The design should avoid any external lights and aim to cover the minimal area of the wearer's head, with any additional coverage focusing on the back.


                    4.

                    Envision a headworn wearable that merges functionality with understated elegance. For wireless galvanic vestibular stimulation, the black device should have electrodes on the two mastoids and both sides of the forehead, ensuring they don't extend too far from the hairline. The design should be devoid of any external lights and should be as unobtrusive as possible, covering the least head area and favoring the back if more coverage is needed.


                    5.

                    Create a wireless galvanic vestibular stimulation wearable that is the epitome of subtle sophistication. In a muted black tone, the electrodes should be placed on the two mastoids and the left and right forehead, without crossing too far into the hairline. The design should steer clear of any external lights and strive to be as minimal as possible, with a preference to cover the back of the head if additional coverage becomes necessary.


                    These refined prompts should better align with your vision and the feedback you provided.

BrainJam AI Generated Images Round 2

What I learned from these: - WOW THESE ARE SEXY! - it didn’t get the whole idea of not covering the forehead - 1 did, but it looks not great - maybe headband is best because people are used to what contiguous headbands look like?
