• But lets look at GPS and accelerometers

GPS – What you getAttribute Description Unit

latitudeThe geographical coordinate with a value between –90 to +90 degrees. Negative latitude denotes south and positive latitude denotes north.

Degrees

longitudeThe geographical coordinate with a value between –180 to +180 degrees. Negative longitude denotes west and positive longitude denotes east.

Degrees

altitude Vertical height of the geographical coordinates (Latitude and Longitude). Meters

horizontalAccuracy(Accuracy) The horizontal accuracy of the position denoted by the geographical coordinates (Latitude and Longitude). Meters

verticalAccuracy(Altitude Accuracy) The vertical accuracy of the position denoted by the geographical coordinates (Latitude and Longitude). Meters

speed The current ground speed of the device. If the device is stationary, the value of this attribute will be zero.

Meters per Second

timestamp

The time since the application was initialized. For example, if the application has captured geolocation data for four seconds after it got initialized, then the value of this attribute will be 4000.

Milliseconds

Accelerometers – What you get• accelerationX—Acceleration along the x-axis, measured in g’s. The x-axis

runs from the left to the right of the device when it is in the upright position. (The device is upright when the top of the device is facing up.) The acceleration is positive if the device moves toward the right.

• accelerationY—Acceleration along the y-axis, measured in g’s. The y-axis runs from the bottom to the top of the device when it is in the upright position. (The device is upright when the top of the device is facing up.) The acceleration is positive if the device moves up relative to this axis.

• accelerationZ—Acceleration along the z-axis, measured in g’s. The Z axis runs perpendicular to the face of the device. The acceleration is positive if you move the device so that the face of the device points up. The acceleration is negative if the face of the device points towards the ground.

• timestamp—The number of milliseconds at the time of the event since the runtime was initialized.

But, aren’t these all the same?

• Yes, a more interactive mouse.• Can we do more?

Digging• The winners of this

year’s hole digging contest managed to dig a 3.26-meter-deep hole, and took home the 100,000 yen ($1,215) cash prize. It didn’t exactly make them rich men, but it was an original way to spend a Sunday.
