Figure 2: Front Side of HTC HD2
The HTC HD2 is the first Windows Phone which is designed on this capacitive screen
technology with 4.3 inches screen. Capacitive sensing is a technology for detecting
proximity, position, etc., based on capacitive coupling effects. Capacitive sensors detect
anything which is conductive or having dielectric properties and can replace mechanical
buttons with capacitive alternatives such as multitouch and gesture based.
The front speaker and the charging LED located above the screen and on the left of this
grille have two sensors just below the glass surface. First sensor is the proximity sensor and
the second is the back light sensor. Below the screen is one single row of five buttons for
pick up the call, home, windows, back and hang up the call.

The picture above shows perfectly clean topside of the HTC HD2 without any buttons. The
topside used to be the place where users could find dedicated power buttons in the past
Backside of HTC HD2
Figure 7: Backside of HCT HD2
The backside of the HTC HD2 is mainly dominated with the brushed metal battery cover.
In the upper part there is 5 megapixels camera. Remarkable is the fact the camera lens
sticks a few millimeters (+/- 2.5) out the surface of the backside. However there is a minor
edge which protects the camera lens from scratching if you put the device on the table.
Furthermore on the right side of the camera lens, there is a dual LED flash which supports

1.4 Detailed look at HTC Sense
The HTC HD2 is the first Windows Phone with HTC Sense installed, HTC Sense interface
allows users to personalize their phone. HTC's Sense, a desktop-like user interface that
integrates information such as local weather forecast and social networking services such asFacebook, Flickr and Twitter on a single home screen that users can easily access. The tabs
available in HTC Sense are: (1) Start, (2) Contacts, (3) Messages, (4) Mail, (5) Internet, (6)
Calendar, (7) Stocks, (8) Pictures and Videos, (9) Music, (10) Weather, (11) Twitter, (12)
Footprints, (13) Settings. All the tabs (except for Start and Settings) can be enabled or
disabled, and apart from the Start-tab all the tabs can be re-ordered according to users
preferences.
Start / Home
Figure 8: Start/Home
The Start Tab shows directly on the top the Carrier. Under the carrier bar there are several
widgets which cannot be turned off (like the Android Sense Widgets). The most top widget
is a widget which shows the current time, the current location and weather information
about the current location. When you tab on this widget a separate application within sense
opens with 2 tabs:

Alarm clock application.
The world-clock application shows the time from different places around the world. There
is option to add users own city here. Next to the world clock application there is the
Alarm tab. The alarm tab has 3 alarms. Each alarm can be set to a specified time and day.
Below the Time-widget on the Start Tab there is another widget which shows the date,
the next time the alarm will go and the next appointment. The alarm button brings you to
the same Alarm tab described in the widget above. And when you click on the next
appointment you go the Agenda-tab of the HTC sense interface.
Below these widgets there are 3 widgets which can be used as a shortcut to an application,
contact or a bookmark.
Contacts
Figure 9: Contacts
The contacts tab, shows 9 directly access shortcuts to users popular contacts. There are
more shortcuts if users scroll up, so in total in the contacts tab there are 15 contacts which
can be set as favorite.

With footprints it is possible to add metadata to photos. This metadata includes a rating,
Category, GPS location, Phone number, web address and more. The tab Footprints let users
flip through the footprints which they created in the past and lets they add new footprints. A
particular nice feature of footprint is the integration with Google Maps and CoPilot. Google
maps shows the street view (if available at that location) and CoPilot Live lets users
navigate to that location.
Settings
Figure 19: Setting
The tab setting gives user a quick access to the most used setting. In this tab they can
change the settings of HTC Sense itself but also other phone settings like Wireless settings,
Sound settings and other settings.
Other software highlights
HTC has put a lot of efforts in the HTC Sense interface but there are a lot of additional
(third party) applications included as well.

Wi-Fi Router
Figure 20: Wi-Fi Routers
The first highly interesting application, developed by HTC themselves, is the Wi-Fi-Router
application. This is a simple one-click solution to turn the Windows Phone into a router.
This can be a really helpful application since, in for example a project group working in an
out of the office location can work on a project and stay in touch with the corporate
infrastructure, in a simple way. Windows Mobile was already known for its Internet
Sharing application, in which the Windows Phone becomes the modem of your Windows
powered notebook. However this Wi-Fi-Router application takes it one step further, and
you can easily now share your cellular data connection with others as well.
JETCET PRINT 5
Another valuable application is the JETCET PRINT application v5. With this application
users can print documents stored on their HTC HD2 to a Bluetooth or network printer.
Adobe Reader LE
Probably not amazingly shocking is the availability of Adobe Reader LE version 2.5 on the
HTC HD2. The massive and ultra clear 4.3 inches screen of the HTC HD2 makes it
possible to read .pdf files easily, and without hurting users eyes. Again this is an example
-
8/2/2019 Interaction Evaluation Project
19/27
19Interaction Evaluation Project: HTC HD2
which shows the versatility of the HTC HD2 and the balance of work and life coming
together in one device.
Facebook
Some time ago Microsoft releases a Facebook application for Windows Phones, to keep
track of users Facebook page while on the go. This application is included with almost
every Window Mobile 6.5 device, and users can check out our detailed review.
Multitouch on the HTC HD2
One of the new exciting features of the HTC HD2 is multitouch. Multitouch is one of the
methods users can use to interact with the screen. It allows them to use two or more fingers
to interact with the HTC HD2 by placing them directly on the screen. Any movements you
make with your fingers will create a gesture, which sends a command to the screen.
Gestures can be used to rotate or to scale a photo or picture.
When users use the photo gallery on the HTC HD2, they can use your fingertip to browse
through the pictures. When they move their finger from right to left across the screen, the
next picture will be displayed.
If they want to scale a picture, they can use multitouch, by placing 2 fingertips on the
screen and slowly moving them away from each other. This causes the picture to beenlarged. Users can reduce it by moving their fingertips in the opposite direction. They also
can rotate a picture by placing their fingertip on the screen and slowly make a circle. This
will cause the picture to rotate.
Users also can use the scale or zoom function in the Opera browser to zoom in or out on
web pages. This gives them the advantage to view a website in normal layout and if you
want to read an article, just zoom in on that particular part. Multitouch is a very handy
feature on the HTC HD2.

Haptic feedback, Proximity Sensor and G-Sensor
Figure 21: Haptic feedback, Proximity Sensor and G-Sensor
The HTC HD2 also features haptic feedback, this means that the device gives you tactile
feedback when users press the screen within TouchFLO 3D. With every screen tab users
will feel a little vibration that confirms that they have touched the screen. It is enabled by
default and cannot be turned off.
The HTC HD2 also features a Proximity Sensor. An extremely cool and useful feature ofthe HTC HD2. It senses whether the device is being held next to your ear. Once the device
is raised up to your ear, the Proximity sensor immediately turns off the screen in order to
save battery life. Moving the device away from your ear turns the screen turns on again.
PDA screens by nature are one of the biggest battery drains, especially when a screen is as
large and bright as this one.
The HTC HD2 has also a built-in G-Sensor. The G-sensor automatically turns the screen to
landscape when users turn the device over. This is very useful when they want to type a
message in landscape. However HTC has developed another cool application based on the
sensors available in the device, which is a digital compass. A screenshot is shown above
(right).

4. Conclusion
There are many possible reasons for companies taking a decision to implement ERP in their organization.
The advantages that ERP could bring to an organization seem to be the obvious reasons such as the
efficiency of their business process, the enhancement of the system as well as reducing software
maintenance, just to name a few. Besides that, ERP was a reason to overcome Y2K issue. The integration
across the departments is always a good advantage that can be gained from it. Database centralization can
as well be implemented which can eliminate data redundancy and increase data integrity. In terms of
business perspective, ERP helps to accommodate the business growth and improve their business
efficiency. Besides, it can also reduce the expenses spent for business operating and administrative.
