Darkball on the App Store on iTunes
"Cristiano Ronaldo can famously volley a corner kick in total darkness. The magic behind this remarkable feat is hidden in Cristiano’s brain which enables him to use advance cues to plan upcoming actions. Darkball challenges your brain to do the same, distilling that scenario into its simplest form - intercept a ball in the dark. All you see is all you need.

One of the brain’s fundamental functions is to use information from the past and present to predict the future. This function is key to how animals, from dragonflies to humans, navigate a dynamic and uncertain world. To make predictions, the brain must have an “internal model” of the system it interacts with. A basic form of this function is at play when we move our body. For example, to reach for a cup, the brain must have a model to predict how the hand would respond to various motor commands. Internal models are also thought to play a crucial role when we mentally predict future states of the environment, for example when we track a ball as it moves behind another object. Here, we have designed a simple task to understand how the nervous system makes such predictions. In this task, subjects have to intercept a ball when it reaches its final position. By changing the speed of the ball, the intervals when it is invisible, and the target position, we will test various hypotheses about the algorithms that are used to integrate information about past and present to make predictions about future."

Tempra on the App Store on iTunes
"Test and increase the accuracy and precision of your sense of time.

For each trial, your goal is to get as close as possible to the displayed target time.

Breathe... relax, and focus on your internal sense of time.

Designed and built by Che-Wei Wang

"It’s called Tempra. It’s a simple game about absolute time. If you ever played the 10 second stopwatch game, you’ll get this right away. It’s that, but 0.5 seconds to infinity.

Our internal sense of time is subjective. It is localized by our culture, swings with our moods, and is affected by body temperature. But time is absolute. One second is defined as “the time that elapses during 9,192,631,770 cycles of the radiation produced by the transition between two levels of the cesium 133 atom.”[google:1 second] If we handed out stopwatches to a million people and asked them to intuitively time one second, where would we land? What would the average be? the median? deviations? We all know what we think one second feels like, but do we know how accurate that feeling is?

Tempra encourages users to train their internal time production in sub-second to minute long durations. It’s a lightweight casual game that’s very much like a stopwatch, except you can’t see the numbers. To play you must rely on your internal sense of time. The goal is to get as close to a given time increment as possible. Each level in the game increases in difficulty by lengthening the duration you have to model in your head. Each trial of the game requires greater concentration, encouraging you to deepen your inward focus and continuously sharpen your internal sense of time.

Practice, like with any other skill, yields higher accuracy. However, we don’t know if accuracy is generalizable. For example, if your sense of two seconds is super accurate, does that also mean you’re good at dodging traffic?

We also don’t know if time production is a skill that you can exercise like a muscle. Can you strengthen that muscle? Probably. Does it atrophy if it isn’t exercised explicitly? We don’t know.

If internal time production is a muscle that you can exercise, and if exercising that muscle has generalizable attributes, then practicing with Tempra may have profound effects on your health and well-being.

To gain insights into how our brain distorts time and generates biases towards time production, Tempra anonymously collects data from time production trials from players around the world.

We won’t know unless we try."]

CW&T » Crow's Flight
"Crow’s Flight is a GPS compass app for the Android platform. Enter an address and the GPS compass will continuously update your position and point towards the destination. Distance to the point is displayed in meters or kilometers along with a visual distance gauge.

The red line always points north. The triangle points in the direction of the destination. The brightness of the triangle indicates the accuracy of your GPS fix. White being accurate and darker shades being less accurate.

To get it on your android device, go to the Market app on your phone and search for “crowsflight”. or click on the link->crowsFlight (only on Android devices)

Usage:
Go to the menu to record your current location so you can point back to it later.
Enter an address at the top textbox and press go.

crowsFlight is primarily meant for walking. Use it to track where you parked your car, camping, hiking, geocaching, getting lost, finding your way, hiding treasure, etc.

more features coming soon
-closest subway
-mark “here”
-show in maps
Crow’s Flight is open source and FREE.

If your compass is acting weird, try calibrating it by spinning the phone on a flat surface really fast. Really. It worked for me."
