Wearable Polygraph

Image
Today I am going to outline the plan for an upcoming project. Concept: By measuring numerous sources of information on the human body I intend to evaluate the information that is made available involuntarily when someone speaks. By using running averages, statistical modeling, or a neural network along I will try to go beyond current work in Human Activity Recognition to detect variations from "Normal" responses. This task is my attempt to make a general purpose wearable polygraph machine . In this post I will demonstrate a more full explanation of the concept, outline the technical requirements that this will involve, give some background on expected audience and environment, and finally go over the materials that I plan to use to successfully implement this idea. Requirements: To accomplish the goal of this project I will need to monitor a multitude of body sensor data in real time: Breathing rate   Pulse (heart rate) Muscle Activation (involuntary nervous

Soft Switch

In this episode we are going to demonstrate another simple project for getting introduced to circuits and sewing. Our goal here is to make a soft switch by sewing a button onto a square of felt to close the connection. This will cover many of the same skills as the previous introductory project . However, developing garment skills and circuit skills takes practice and every new project reinforces those abilities. As before, here are some useful links for this project: Sparkfun E-Sewing Basics Kitronic E-Textiles Spakfun parts Adafruit inspiration Without further ado lets collect our materials and get rolling! Materials: For this quick project we will need many of the same items we have used before. Felt Square Sew on Snaps> Conductive Thread Coin Cell Battery LED Light Coin Cell Battery Holder Other items that are useful but not required are sharp scissors that can cut felt, rip-stop , and clear nail polish . Steps: 1. Buttons: Once you have the m

Simple Soft Circuit

In this post we are going to walk through an introductory soft circuit. Materials Conductive thread (~2 feet)   White thread Coin cell battery Coin cell battery holder LED light (sew-able or regular) Embroidery hoop Felt Square Hot glue gun. Get Going! 1. Collect and assemble materials! Collect the materials, they can be found at most local craft stores, or on your favorite web market. To make yourself ready to get creating, we need to get the felt into the embroidery hoop and the conductive thread into the needle. To prepare I put the felt square into the embroidery ring along with a small piece specially cutout for the design that I had in mind. 2. Sew what? The basics of sewing and their relevant techniques in wearable technologies can be found on sparkfun (an amazing resource). Holding the LEDs and the battery holder in place while trying to sew them can present a challenge as most of us have ten fingers at the best of times. To assist, I suggest using h

Re: Why Google Glass Broke

  Google Glass was a magnificent failure with a high interest story behind it. In this post I will be giving a quick response to the story published in the New York Times with some perspective on the context and aftermath that google glass left. Don't be like Google. The Story In late 2009 some of Google's top executives coalesced for a secretive meeting to discuss the future of technology and all the crazy ideas that Google might be able to capitalize upon. While many different projects were allegedly spawned out of this meeting we are only interested in one. Google Glass. Google glass was developed in secret on the Google campus as Project X a project that not even regular Google employees had knowledge about. For two years the project was under design and development until 2011. Against the wishes of some of the developers Google glass was making it's way onto the world stage. Originally the plan was to start with a limited release, to critics and open s
