Wide Range of Ubiquitous Technologies: • Personal Devices: • Mobile Phones (3G, EDGE, GPRS, Bluetooth) • PDA’s (Bluetooth, WiFi) • MP3 Players • Laptops (Bluetooth, WiFi) • Cameras/Camera Phones • Digital audio recorders (Dictaphones/PDAs) • New generation of integrated devices • E.g. Hugh has a HP GPS PDA Phone, with GPRS, Bluetooth and enough memory to act as an iPod Nano • Located Devices • Touchscreens, Intelligent Signs • Desktop PCs • Location Technologies: • Global Positioning Systems • Cell based (for mob phones) • Bespoke (e.g. ultrasonic positioning)
What are the Contextual Considerations? • What is permissible in the environment? • Radio frequency restrictions • Privacy Issues (photos, audio recording, etc) • Data protection (if integrating with existing systems) • What is intrusive? • Notifications (sounds, lights) • Input mechanisms (keyboards, stylus, mouse, voice, touch) • Mobile devices • easy to carry/use • Located Devices • easy to maintain in the environment
Other Considerations • What do students and mentors already own? • Leverage existing technology infrastructure • No learning curve • Easier to incorporate into existing practise • People may be unwilling to replace their own devices (i.e. may want keep their own phones) • Development effort • Easier to build apps for laptops than PDAs, easier to build apps for PDAs than phones • Browser based (Web/WAP)? • Possible to have multi-access (via a range of devices) • Costs • Are their external contributions? • Is part of the point to make it affordable? • What happens if someone loses or breaks a device?
Technological Aim Our aim (although we may not be able to realise it - it’s a lot harder than it sounds) should be a toolkit that: • Uses existing devices wherever possible • Can be accessed in a variety of ways (phones, PDAs, Web browsers, etc) • Is composed of simple apps that are loosely coupled (perhaps as REST services) • Function as independently as possible • Can be used/combined in a number of ways as needed
