These Devices Respond to Natural Human Touch<br />
These Devices Respond to Natural Human Touch<br />This works in a few different ways<br />
Method 1<br />Each device has an acrylic or glass surface<br />A finger touches the surface causing light to scatter<br />The reflection is picked up by sensors or cameras<br />The gesture is sent as data to software<br />The software interprets the data and initiates the appropriate response<br />
Method 2<br />A pressure-sensitive coating is applied to the screen surface<br />The coating flexes under varying pressure of the touch<br />Sensors interpret the pressure<br />The data is sent to software which relays the appropriate response<br />
Method 3<br />Handheld devices have panels that carry an electrical charge<br />The touch disrupts the electrical field<br />The disruption is registered and sent to the software<br />The software interprets the gesture and initiates the <br />appropriate response<br />
But this isn’t new technology<br />There were important breakthroughs beginning in 1953<br />
The first touch sensitive technology was invented in 1953<br />By Canadian <br />Physicist and Composer <br />Hugh Le Caine<br /><ul><li> He built the first music synthesizer
He invented the </li></ul>touch sensitive keyboard<br />collectionscanada.gc.ca<br />
In the 1960’s the power of computers was realized. <br />1960 <br />The DEC PDP-1<br /><ul><li> The PDP-1 sold for $120,000.
MIT wrote the first video game, Space War! for it.
Software then initiated program responses </li></ul>hp.com<br />
This same technology was used to create ATM’sin the 1980’s<br />plippard.com<br />
In 1992,computers became mobile <br />The Apple Newton: <br />The first PDA (Personal Digital Assistant)<br />This brought together many <br />previous technological innovations<br />Pen Computing Technology <br />Handwriting Recognition Software<br />Gesture Recognition <br />It also introduced Apple’s 1sttablet platform. <br />(Apple’s 2ndplatform is used in <br />the iPhone, iPod Touch, and iPad.) <br />gdgt.com<br />
These innovations and breakthroughs allow us to interact with our devices using Natural Human Gestures: Touches, Swipes and Taps<br />
