A smart device is an electronic device capable of interactive and autonomous operation, connected via various protocols. Smart devices can be categorized by form factors such as tabs, pads, and boards, and possess characteristics like dynamic resource access and context awareness. While they offer significant advantages, such as enhanced accessibility and functionality, they also present challenges, including potential addiction and misuse in educational contexts.

2. Definition
 A smart device is an electronic device,
generally connected to other devices or
networks via different protocols such as
Bluetooth, NFC, Wi-Fi, 3G, etc., that can
operate to some extent interactively and
autonomously

4. Form factors
 In 1991 Mark Weiser proposed three basic
forms for ubiquitous system devices: tabs, pads
and boards.
• Tabs : accompanied or wearable centimetre sized devices,
e.g., smart phones, smart cards etc.,
• Pads : hand-held decimetre-sized devices,
e.g., laptops.
• Boards : meter sized interactive display devices, e.g.,
horizontal surface computers and vertical smart boards.

6. Characteristics
 Smart Devices can be characterised as follows:
• A set of system hardware & software ICT resources. This set is
usually static fixed at design time.
• Dynamic component-oriented resource extensions & plug-ins (Plug
and play) of some hardware resources.
• Remote external service access and execution.
• Local, internal autonomous service execution
• Access to specific external environments: human interaction, physical
world interaction and distributed ICT / virtual computing interaction.
• Ubiquitous computing properties.
 Common types of smart devices include:
 Tab and pad type smart devices that often as act as personalised #smart mobile
devices
 Smart environment devices.

8. Mobile Devices
• Multi-purpose ICT devices e.g., personal office, mobile phone,
camera, games console, etc
• Multi-functional support eases access & interoperability of multi-functions
at run-time but this can lead to a decreased openness
of the system to maintain (upgrade) hardware components and
to support more dynamic flexible run-time interoperability.
• Personalised, configured to a specified owner. Device access can
be secured only for the owner.
• Operates as a single portal, e.g., a Web portal.
 Smart mobile device service access is characterised by:
 Open service discovery
 Intermittent resource access.

9. Smart Mobile Devices
 Highly portable devices becoming increasingly
popular:

10. Mobile Smart Devices
 Examples:
 Personal Digital Assistants (PDAs)
 iPhone and other “smartphones”
 iPad and other tablet PCs
 Portable game consoles with wireless connectivity
(e.g. Nintendo DS and Sony PSP)

13. Ubiquitous Computing Properties
 Weiser’s vision for ubiquitous computing can be
summarized in terms of three core properties:
 Devices need to be networked, distributed and transparently accessible.
 Human Computer Interaction with devices is hidden to a degree
from its users.
 Devices exhibit Context awareness of an environment in order to
optimise their operation in that environment.
 It is proposed that there are two additional core types of
properties for UbiCom systems:
 Devices can operate to some extent autonomously, i.e., without human
intervention, be self-governed.
 Devices can handle a multiplicity of dynamic actions and interactions,
governed by intelligent decision-making and organisational interaction.

14. Environments
 The term Smart Device Environments has two meanings.
First, it can refer to a greater variety of device
environments. Three different kinds of environments for
devices can be differentiated as:
 Virtual computing environments that enable smart devices to access pertinent
services anywhere and anytime.
 Physical environments that may be embedded with a variety of smart
devices of different types including tags, sensors and controllers.
These can have different form factors ranging from nano to micro
to macro sized.
 Humans environments : humans, either individually or collectively,
inherently form a smart environment for devices. Such as mobile
phones, pacemakers etc.,

15. Smart Devices versus Services
 Devices may access or offer one or many
services from other devices.
 Services may be split across several devices or be
offered by multiple types of services.

17. Information Appliances versus
Smart Devices
 Smart Devices are characterised and differ in several
key ways.
 First, Smart Devices in general can take a much wider range of form-factors
than appliances.
 Second, Smart Devices support the ubiquitous computing properties.
 Third information appliances focus on remote interaction with
computing environments that tend to be personalised whereas Smart
Devices can also focus heavily on impersonal physical world interaction.
 Four, the term appliance generally implies that devices are task specific
and under the control of some embedded system or application specific
operating system, whereas Smart Devices may support multiple tasks, e.g.,
a mobile phone can act as a phone but also as a games console, music
player, camera, etc.

19. Overview

22. Conclusion
 Smart devices have good and bad sides.
 According to the research smart devices only have the
disadvantages of addiction and not using for the right
purposes some times. With the type of world that we have
today smart devices are very useful.
 I think that smart devices do have an effect on education in
both good and bad ways. It makes it easier to research but
some students abuse them.
 In conclusion I think we really need smart devices these
days because they have good effects.
