Internet Today
• Those using their mobiles to connect to the internet have grown in number from 55% in late 2011 to 65% by the end of 2013.
• During the same period, going online via a tablet grew at an even faster rate – from just 12% up to 29%.
https://www.globalwebindex.net/
• Indonesia has around 236.8k mobile phone users with population 237,556,363 so the penetration is about 99.68% (on September 2013) – “CIA – The world Factbook”, 14 January 2014.

Internet of Things (IoT)
http://www.agtinternational.com/technology/internet-of-things/
• Everything value will be on the network in one form or another
• All objects will be interacting and communicating with each other

IoT in Context-Awareness Perspective
• Identify (Who)
• Activity (What)
• Response (Environment)
• Location (Where)

Our Goal … Our goal is:
to make user interacting with “the things” easier in the smart environment where “the things”: • spread throughout (pervasive), • are everywhere at the same time (ubiquitous), and • Are embedded (ambient) in the environment.
The UI needs not to be difficult, tedious or need hard learning to the user.
It should potentially be: • safe, • easy, • simple, and • enable new functionality without need to learn a new technology.
It provides relevant information and a simple way for a user to deal with it.

Sensors and Trend of Sensing in IoT
![Page 23: PowerPoint Presentation2014.icoict.org/wp-content/uploads/dl/Teddy... · For example: mobile phone, PDA and tablet with a Bluetooth and/or WiFi enabled device. In case a user has](https://reader033.fdocuments.us/reader033/viewer/2022042416/5f3206ef5aabd6176a1e3d32/html5/thumbnails/23.jpg)
Type of Sensors
• Three types of sensors: • Precise Location (Fixed sensor) • Proximate Location (Proximate sensor) • Predicted Location (History Location)
![Page 24: PowerPoint Presentation2014.icoict.org/wp-content/uploads/dl/Teddy... · For example: mobile phone, PDA and tablet with a Bluetooth and/or WiFi enabled device. In case a user has](https://reader033.fdocuments.us/reader033/viewer/2022042416/5f3206ef5aabd6176a1e3d32/html5/thumbnails/24.jpg)
Not all sensors/devices can be represented as a user identity in a smart environment (home/office). The requirements for a sensor/device to be a user/device are:
• used as a personal and privacy device • have capability to connect to the network with certain MAC address.
For example: mobile phone, PDA and tablet with a Bluetooth and/or WiFi enabled device.
In case a user has more than one devices, then the latest sensor data that store in the repository will be used as a current state.

VisUN-3D: Visualization and Navigation
VisUN-3D for user navigation needs the following information: his location in the 3D map his location in the 3D walk-space the target location to meet his colleague location in the 3D map his colleague location in the 3D walk-space.

Co-processing Interactive Architecture
Structural-view navigation. This process will produce a 3D map and 3D walk-space for user navigation (navigation
object tools) using hierarchy of the symbolic (name) location instead of coordinate location.
Spatial-view navigation, which navigates in the 3D walk-space and animates the
object to get an equivalent view between the 3D walk-space and the real campus environment (interface between navigation objects and 3D maps).

Bi-A* Pathfinding Algorithm
Bi-A* pathfinding algorithm is an extension of Dijkstra/Prim algorithm and Best-First-Search algorithm for VISUN-3D environment. This algorithm can be used for routing 3D requirements in a 3D software development for visualization and navigation purposes. The complexity of this algorithm in navigate two users is | h(x) − h * (x) | = O((log h * (x))/2) (note: x=current of user location h*=optimal heuristic, the exact time/distance to get from current user location (x) to the target)
