      Hi Dani,
      Here are some more comments.

      Great stuff, really exciting. It has moved a lot in 3 weeks.

      Video: great and engaging. If you can do a few more shots. Could you show one where someone else is triggering your thumb? or another part of your body? alternatively that could be use as a gif in the page.

      Could you also hint at people who might want to join the project? Those who might want to work with you at developing it. Kickstarter is good for this too. Around 1:13”. Don’t reshoot yourself in camera, your good and you won’t be able to set the light the same way.

      Could you do another photoshoot and add some context pictures. Different weird things you could do with it. You already have a lot in your video that you could take screenshots of. How about giving it to a kid and taking a picture of them using it?

      Hola Dani,

      Here are some feedback:

      Subtitle:
      “The Third Thumb is design project exploring human extension and prosthetics through user hands on experience. “
      The Third Thumb is A design project…
      thought user hands-on, with “-“

      Why is the Third Thumb on Kickstarter section:
      What is the “next stage”?

      Could you say that you would like at least 13 users to try out the third thumb but if there are more backers who wants to join the project they can do it too of course. By this, I mean that you can use the platform to get people interest in the project and you might end up with a lot more people willing to test it than 13.
      The more backers willing to try it out, the better!

      You should show a few weird/fun/inspiring applications the thumb is doing at the moment. For the purpose of getting backers intrigued.

      You will have to show some project dates and important milestones that you will reach until the project is declared “finished”/.

      Rewards:
      They are good. However I think there might be too many “small pledges”. You could remove 2-3.
      Then after the main reward at £83, it jumps to £1300. It would be wise to offer something at £200 or £500.

What is a prototype?

A prototype is a preliminary model of something. Projects that offer physical products need to show backers documentation of a working prototype. This gallery features photos, videos, and other visual documentation that will give backers a sense of what’s been accomplished so far and what’s left to do. Though the development process can vary for each project, these are the stages we typically see:

Proof of Concept

Explorations that test ideas and functionality.

Functional Prototype

Demonstrates the functionality of the final product, but looks different.

Appearance Prototype

Looks like the final product, but is not functional.

Design Prototype

Appearance and function match the final product, but is made with different manufacturing methods.

Production Prototype

Appearance, function, and manufacturing methods match the final product.

About this project

What is the Third Thumb Project?

The Third Thumb is a design project exploring human extension, prosthetics and robotics. It enables a better understanding of connecting technology to the body through a hands on experience.

The Third Thumb is a work in progress, it is at a stage in its development that I need people to contribute to help further the design. I want you to experience the strange behaviours it creates and explore the different situations it can be used in.
  


The Third Thumb originated as a project to better understand prosthetics; by understanding what it is like to control robotics and prosthetics from alternative points in our biological bodies, we can begin to understand the challenges and interesting insights on a design level, faced by people in the prosthetics community. This can generate a better understanding of prosthetic design.
 


It’s a prosthetic, but not medical prosthetic. The Third Thumb is for anyone interested in exploring movement and connection of technology to the body. It’s a part of a process to better understand prosthetics and wearables. The origin of the word prosthesis means to ‘add on’. We need to see prosthetics as technology that aids and extends, not fixes or replaces. The Third Thumb project aims to expand the positive perception of prosthetics through experience, and also have a bit of fun.
 

 
Why is the Third Thumb on Kickstarter?

I am crowdfunding for two reasons; firstly, I need some support to progress this project to the next stage, and secondly I need some awesome people to wear the Third Thumb, to explore what is does and doesn't do, weird behaviours it creates, and the connection formed between the wearer and the prosthetic.

I want to find like-minded people anywhere in the world, who are just as interested in this as I am. I would like to create a community of people in different environments, that would be willing to receive Third Thumbs and feedback and discuss interesting insights and become part of the design process.

The money pledged for the Third Thumb goes solely toward creating these prototypes, and sending them too you. Please keep in mind that this is not a final product, it is a work in progress.

The project will be finished in November 2017 once I will have sent out of the Third Thumbs (in July) and received feedback from you all.

The other Third Thumb pledges will go towards the support and continuation of this project. Receiving feedback from my Third Thumb wearers will help me to develop the prototype further, you will receive updates of new progress and designs.
 


Who am I?

Hi, I'm Dani, I am a product designer from New Zealand, currently completing the final year of my MA at the Royal College of Art in London.
Originally from New Zealand, I moved to London 3 years ago.
  
  

How does it work?

The Third Thumb is attached to your hand with a silicone strap, and connected via two cables to a small servo on the back of your hand. The flex sensor is how you control the Third Thumb; it runs up within the silicone of your little finger cover and as it is flexed, the resistance across the sensor increases. This then moves the servo controlling the Third Thumb in time with your finger. All of this is operated by a small chip called a Arduino Micro (about the size of a thumbprint), which will be positioned near the small servo.

The main challenge at this stage will be the battery. At the moment the design is running off a small external battery pack, but this will hopefully be replaced with a small lithium battery.

  

Materials and Development:

I developed the Third Thumb on my own and it is still in the prototype stage.

The Third Thumb prototype will consist of:
A mini servo

3D Printed Parts

An Arduino Pro Mini

A Flex Sensor
Assorted wiring

1mm Acrylic
A Silicone Hand strap*

*Please make sure you send me your hand size by printing the following document on A4 to letting me know.

(Battery not included)

The Third Thumb is currently a work in progress. The deliverables at this stage in the process will be manufactured by me.

Thank you for your support!

Risks and challenges

Due to this being a work in progress design, there of course can be issues that occur, especially when it comes to electronic parts.

I have completely designed the Third Thumb myself, so if anything was to go wrong, I can guarantee a quick replacement or resolution of the issue.

All quotes for costs are as accurate as they can be currently, but due to this being a design research project of mine, I will personally take care of costs if necessary.
