High Five Glove Prototype?!

A project log for ATLTVHEAD

Atltvhead is a mashup of interactive art and wearable technology with a message of positivity and encouragement to let your oddities shine!

Hackaday has awarded this project with the HCI award and some financing to help the project. First off, thank you Hackaday!!!!! To reinvest some of the money into the project, explore more HC interactions, and to enhance the Atltvhead experience I am building a high five sensor.

Most of the communication goes one way, chat types -> the tv changes. But I want to give some IRL people control in chat (at least emoji spam). Allow for some physical action to have a digital presence, just as chat's digital presence impacts the physical screen.

The Needs:

The Desires:

A large part of my design decisions were based around my 1 week constraint. I wanted as close to a functional prototype glove done in time for this weeks stream. So here are the materials I had on hand when deciding what to do:

Luckily the Esp32 has some capacitive sensing pins and features. It even has the ability to have a capacitive touch interrupts (oh boi).

int threshold = 62; // The higher this number the more sensitive the touch capabilites. 
bool touch1detected = false;

void gotTouch1(){
 touch1detected = true;
}

void setup(){
Serial.begin(115200);
touchAttachInterrupt(T6, gotTouch1, threshold); //T6 is pin 14
}

void loop(){
if(touch1detected){
    touch1detected = false;
    delay(500); // timer based debounce
    Serial.println("Touch 1 detected");
  }
}

The Build

For the Esp32, I took the conductive thread, wrapped it around pin 14, soldered the pin closed, superglued the thread, and cut it (I decided not to use the velostat). I rushed a rough CAD housing for the esp32 with some features to hang onto the wristband (files are located in the file section of this project). Lastly, I took the other end of the conductive thread and sewed it into the biking glove. At the end it all ended up looking like this:

What Impacts Atltvhead?
When a high five is detected, I triggered the power puff girls style animation to play with whatever color settings for the heart are currently present (something I do not normally allow). The animation ended with a sparkle effect being applied for about a minute. Also the chat gets flooded with twitch emotes! yay! party!

// I added this to where the chat is being read in my atltvhead code
else if(ircMessage.text =="High Five Mode Initiated"){
      color = cHue;
       for(int ppgLooper =0; ppgLooper <= 3; ppgLooper++){
        for(int indPPG =0; indPPG<=5;indPPG++){
          ppg(indPPG);
        }
       }
       color = 211;
       chanel = 4;
       channelSwitch = true;
}
 



What is next?!
As of today, I tested it live during a stream. I'll have a highlight video out later this week. There are a good amount of hickups with this design though. How capacitivity changed throughout the stream. I tested it while I was wearing the glove, and even while I was wearing atltvhead to account for the added capacity. However I got sweaty, and sweaty people conduct differently. This caused multiple misfires and endlessly looped the ppg animation.

I plan to get in some conductive fabric and make a soft button to replace the capacitve switch. I know I know, I could code a constant calibration section to the capacitive touch. If it triggers 10 times in less than a certain amount of time, back off the sensitivity and try again. Actually I probably will code this until I can make the soft button.

Oh Well that is all! I plan to keep working on the High Five Glove/sensor for Atltvhead and will get that video out soon! Thank you Hackaday for the support and hope I can use it to grow the project!
