Current Study Concluded

Posted on 2017/05/23

My current study in concluded as my dissertaton defense was successful. I will be starting another series of experiments and will be soliciting a new batch of volunteer in the coming months.

Research Volunteers Needed:Non-Pilots and Pilots

Posted on 2017/03/02

Additional research subjects needed for an academic doctoral study on soaring flight, soaring simulation, and cognitive response to stress. No prior experience with simulators or computers is needed. Participants must be at least 18 years of age.

Participants needed for both the experimental group of glider pilots, and control groups of powered aircraft pilots and non-pilots.

The research is conducted at Long Island Airpark (NC26).

Research Simulator

Research Simulator

Participants in the study:

• Wear two wrist sensors while performing flight tasks in a soaring flight simulator
• Answer a series of questions prior to using the simulator to establish flight experience
• Answer a series of questions about their experience in the simulator at the conclusion of each session

All data collected is anonymized; no personal information will be published or released as part of the study. Research subjects may participate in up to 5 research sessions. Each session is estimated to take 45 to 90 minutes.

Asymmetric EDA

Posted on 2017/01/21

Some unusual assymmetric EDA patterns emerged for some pilot volunteers. Som very unusual SCL patterns also occured for other subjects. Ability to investigate this further was compromised by possible EDA signal loss on some sensors. This may result in some follow-up research once the dissertation study is complete.

Research Location now in North Carolina

Posted on 2015/09/13

The location for the research study have changed. It is now located at Long Island Airpark, in North Carolina. This airpark is on the north west shore of Lake Norman in Catawba County.

 
Participants are still eligible to win an Oudie or iPad through the end of 2015.

Windows Kinect V2

K4W V2 Dev Preview

K4W V2 Dev Preview

Hardware acquisition and evaluation is moving quickly now.  I was accepted to the Kinect for Windows V2 Developer Preview program, in part due to previous work with the Kinect for Windows V1. I’ll be adding this to the hardware & API feasibility mini studies I am conducting for the next 1-2 months, to see what biosignal data for subject affect I can reliably acquire with the Kinect For Windows V2 Preview hardware and APIs.

eHealth Sensor Platform

E-Health Sensor Shield

E-Health Sensor Shield

I have identified an interesting hardware option for building a portable system for the bulk of the sensor/data gathering needed to determine pilot affect: the open source eHealth Sensor Platform. It is Arduino or Raspberry Pi based, and offers a rudimentary API for data gathering from  sensor like:

  • Pulse Oximeter (heart rate and blood oxygen saturation)
  • Electrocardigram sensor (ECG and heart rate)
  • Galvanic Skin Reponse Sensor (GSR – sweating)
  • Electromyogramphy Sensor (EMG)
  • Sphyganomater (Blood Pressure)
  • Airflow sensors (Breathing)
  • Accelerometer (Subject Position)

It also offers a variety of connectivity options in terms of data transport (USB, serial, 3G, GPRS, Bluetooth, 802.15.4, and ZigBee). I’ve ordered the platform and several sensors to evaluate their performance for use in my research. It’s potentially a good fit, as the flexiforce sensors I have decided to utilize are also Arduino/Raspberry Pi based.

EEG Hardware

Posted on 2014/02/02

I’ve identified two potential headsets for EEG data acquisition. Over the course of the next several months I will be evaluating each.

Neurosky Mindwave EEG

Neurosky Mindwave EEG

 

The Neurosky MindWave is a relatively inexpensive ($99) option, but is limited in that it does not have APIs for raw access to EEG data, only to am affect model developed by the manufacture. It also utilized only two EEG sensors, so it is somewhat limited in its reporting options.

Emotiv EEG

Emotiv EEG

The Emotiv EEG headset is a more expensive option (at $250 or $750 depending on licensing), but it utilizes a 16 sensor setup and has APIs for raw EEG data as well as affective models developed by the manufactures., including an api for interpreting facial expressions, emotional states, and subject intent.

A very nice gentleman has donated the intact fuselage from a G104 sailplane damaged in an off airport landing. Over the next year I will be porting the simulator functionality I have developed (and will continue to develop) out of the steel tube frame mockup and into the actual cockpit. Thanks to his generosity research that was planned as post-doctoral research can now be part of my dissertation, and allow for a much more realistic simulator platform.

Flexiforce Sensors

Flexiforce Sensors

One data point I would like to gather on pilot affect/performance is the amount of force applied by the pilot to control during flight. This would involve measuring how the pilot grip strength on controls such as a joystick or air brake handle varies over time, or how hard the pilot pushes on rudder pedals.

A likely candidate for these measurements are piezoresistive Flexiforce sensors from Tekscan, a spin-off of research by the MIT media lab in Affective Computing. These are this, flexible circuits that change resistance based on the amount of force applied to them.

Head Tracking Integrated

Posted on 2014/01/06

I’ve added head tracking using TrackIR. This will allow the simulator pilot to change their view without using a secondary control (such as a keyboard or joystick). It took a bit of tweaking to get the tracking calibrated and the speed and smoothness settings correct. Here’s a quick demonstration video. Note that the instrument panel is not placed in the optimal position. I am moving it to an adjustable mount that I am in the process of fabricating.
