• Use of real finds and junk Children indoors will see finds as they come in Look in catalogue to find whether Roman/Ancient Briton or something else Something about the junk – what it will tell someone in the future about us
• Geo-physics – shows what is underground by measuring changes in soil conditions e.g. resistance We will build a machine to attach to phone We will be going out to play this too Compare with aerial photos and other outward signs We end up with a building floor plan – what might that indicate
• Take the floor plan Decide which are going to be the points where we dig Go outside and mark up points for digging Also put the plan into our art program
• Going to talk about Bombs Away – proposed games, all the phones I have ever owned – less about the technology – a bit of waffle around the edges
• ### Accelerometers in Phones - a workshop

1. 1. Accelerational A few thoughts on the use of accelerometers in games Richard Vahrman - Locomatrix
2. 2. Phones & Tablets - Full of Sensors <ul><li>But lets look at GPS and accelerometers </li></ul>
3. 3. GPS – What you get Attribute Description Unit latitude The geographical coordinate with a value between –90 to +90 degrees. Negative latitude denotes south and positive latitude denotes north. Degrees longitude The 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
4. 4. GPS – What you can do with it
5. 5. Invisible Buildings Here’s our game
6. 6. Metal Detectors
7. 7. GeoFizz
8. 8. The Dig
9. 9. Dinosaurs
