1.3 Functional hardware design

Front side of HTC HD2


7/27


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.

Right side of HTC HD2

8/27


At the right side of the HTC HD2 there is no single button there but it is only the metal

battery cover snaps on the sides of the HTC HD2. In the metal battery there is a slit

where users can put in their fingers nail to remove the battery cover.

Bottom of HTC HD2

Figure 4: Bottom of HTC HD2

The picture above shows the bottom of the HTC HD2, where it has the Micro USB port and

a 3.5 mm headphone jack.

Left side of HTC HD2

Figure 5: Left Side of HTC HD2

On the left side of the HTC HD2 there is the dedicated volume control buttons. These

buttons in can be use in order to change the volume during a voice call. As users can see

that the metal battery cover also snaps around this side of the HTC HD2, but metal battery

cover features a contour that perfectly fits onto the volume control buttons.


9/27


Top of HTC HD2

Figure 6: Top of HTC HD2

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

the camera is less light conditions.

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:


11/27


World Clock application and

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.


12/27


Messages

Figure 10: Messages

The messages tab shows all the text messages. With selecting a message, users can see the

message tab from the people-centric communication. In this view users get an overview

of all the text messages sent from and to this contact.

Mail

Figure 11: Mail

The mail tab shows all the mailboxes that have been configured. When users select a

message users will see the complete message with some additional features.


13/27


Internet

Figure 12: Internet

On the top of the internet tab there is a search bar. In this bar users need to enter a search

term and push the search button. This will automatically open Google and gives the search

results. Under the search bar there is a large button to open the Internet Browser. On default

this will open Opera (Although there is also Internet Explorer installed on the device).

Under the internet browser button there are 8 shortcut buttons in which users can add a

favorite website.

Calendar

Figure 13: Calendar


14/27


The calendar tab has five different views: Agenda, Day, Week, Month and Year. The agenda

view gives a chronological list of items in agenda. The day-view shows all the

appointments on a specific day, and the weather of the location of appointments. The

week-view shows all days of the week, so user can have a good overview of their week.

The month-view shows all the days of the month and shows a little icon on the days that

have an appointment set. When users click on a specific day it will show the day view of

the selected day. The year view shows all the months. When users select a month, they will

see the month view of the selected month.

Stocks

Figure 14: Stocks

The stocks tab shows a list of all the stocks users are interested in. Stocks can be added,

removed or reordered. In the settings of the stocks it is possible to automatically update the

stock information with an interval from 5 minutes to 8 hours. It is also possible to select an

option that lets they download stock update information while roaming. The last setting is

the color of the stocks when the price of the stocks rises. This can be set to green or to red.


15/27


Pictures and Videos

Figure 15: Pictures and Videos

The pictures and videos tab lets users go through the pictures and videos on the device.

When they swipe their finger up they will see the next picture or video. The pictures and

videos tab can be rotated. This view gives them a very nice sleek overview of the pictures

and videos on the HTC HD2.

Music

Figure 16: Music

The music tab shows all the music on the device. In the music tab user can choose to play,

pause, and go to the next and previous song. The music tab also has a landscape view. This

shows a view very similar to the iPhones cover flow. In the landscape view it is also

possible to play and pause the song and skip to the previous and next song.


16/27


Weather

Figure 17: Weather

The weather application shows a full screen overview of the weather. The top part shows

the temperature high and low, and the temperature at the moment. Of course it also shows

the nice animated weather information when it is sunny, clouded or when it rains. The

bottom part shows the same information (temperature high, low, and a small picture of the

expected weather forecast) for the next four days. When users swipe their finger up the

weather of others location will be show.

Footprints

Figure 18: Footprints


17/27


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.


18/27


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


19/27


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.

20/27


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.
