We ran the R simulation below to test our hypothesis that LiF should be able to optimize decoy effects (I will add comments further clarifying my train of thought as reflected by the script within …
Decoy Effect LiF simulation in R
The lock-in whiteboard session
Now that we had successfully run some more simulations with Davide’s and Maurits’s lock-in feedback algorithm, we still needed to decide which real life problems might be the most conductive to LiF’s optimum finding prowess. …
StreamingBandit
I recently added an implementation of our Lock-in Feedback algorithm to StreamingBandit. StreamingBandit was originally developed by Maurits Kaptein and Jules Kruijswijk as “a Python Tornado based asynchronous web server to quickly setup and evaluate …
Where lock-in feedback finds and tracks optimal selling price
After my bare bones Python implementation of Davide Iannuzzi’s and Maurits Kaptein’s “Lock in Feedback” (LiF) algorithm, I thought it interesting to get a better feel for the algorithm’s capabilities and constraints by putting it …
Totem Open Health
Proud to present the Totem Open Health Sensor as the fledgling star of the video above. This sensor is one of the technologies that is being developed in the context of our Totem Open Health …
An introduction to Lock-in Feedback
Currently, I am privileged to be working with Dr. Davide Iannuzzi, Professor in Experimental Physics, and Dr. Maurits Kaptein, assistant professor in Artificial Intelligence, on real-world applications of “Lock in Feedback” – where “Lock in …
Accelerometer step counter in R
To do some preliminary data analysis for the benefit of our Totem Health Sensor, I developed the following simple script. It takes a CSV containing a sensor’s raw accelerometer data (consisting of a time-stamp, an …
UNICEF Wearables for Good: we made it to the finals
The challenge: To design wearable and sensor technology that serves people in resource constrained environments. Our solution: Totem Open Health is currently developing a low-cost, passive, mobile and non-invasive system to monitor fetal health. Monitoring …
Closeness
We just published a basic version of our Android Closeness App on GitHub. It has been made available under a Creative Commons Attribution ShareAlike 4.0 license. This slightly stripped-down version of our Closeness App starts …
Wearable bluetooth thermometers ready for dispatch
Smartphone + ble Disc no1 ready for dispatch! The set will register first 6 months of mother/baby social thermoregulation.
Mediated social support experiment in OpenSesame
I have recently started with the development and implementation of the hard- and software that will enable us to investigate technologically mediated social support during a stressful event (that is, the anticipation of a unpleasant …
Exploratory TurkPrime study: Windfall Bias – Young versus Old
Wandi Bruine de Bruin, Jonell Strough, Marijke van Putten and I have recently set up a study to investigate how a windfall may influence the amount of money younger versus older people are willing to …
A visit to the TNO Perceptual and Cognitive Systems Lab
My visit to TNO Perceptual and Cognitive Systems group in Soesterberg was a little like stepping onto a James Bond movie – or, more specifically, like a visit to Q’s lab. It helps that you …
Teary eyes detector – part three: wink wink
Our cry detection glasses have passed a first real life test in the lab! To the left you see Asmir GraÄŤanin wearing our still very prototype-y looking glasses at his Tilburg University lab. Click below …
Digital thermoregulating bracelet
Wearable technology that controls the temperature you experience through localized heating and cooling. The device resembles a wristwatch with a custom heat sink, attached to an automated control system that automatically adjusts the intensity and …
Teary eyes detector – part two: software library
The cry detector’s basic software library has been completed! We have made the Arduino library and a Processing script to test the library available on Github. Next phase: the lab. Related posts: Cry detection part …
Thermoregulation in romantic relationships
My digital thermoregulating bracelet has just been put to the test in the lab! Today, our first couple took part in our “Social Thermoregulation in Romantic Relationships” experiment. Happily, both the code and the hardware …
