Demo notes/542

This page, a work in progress, will describe the demonstration instructions for Build 542, the Trial 2 Build for the B4 laptops. It is modeled after the B1 Demo Notes page (See Hardware release notes, Software release notes, and Library release notes for additional information).

Important Notes

Please note that the B4 laptops are Beta units and that the software is Alpha; we expect that Trial-3 software will be our first Beta software release). There are bugs (please refer to the bug tracking system at http://dev.laptop.org); not all components are yet operational.

1. There are still some outstanding issues with power management; battery life will not be as good as it will get.

More detail regarding the status of various software components is available on the OLPC Trial-2 Software Release Notes page in this wiki.

Getting Started

An overview of the laptop

Click to enlarge

This figure will be replaced by a B4 unit. Perhaps the most significant change is the position of the microphone, which has moved over to the left side of the bezel and the addition of LED indicator lights above both the camera and microphone.

The keyboard

Keyboard

Touchpad

The center part of the touchpad can be used as a pointing device. The entire surface can be used with a stylus.

Opening the laptop

Position the handle away from you and lift both antennae up and toward you until the laptop clicks open. Lift the screen up from the keyboard; you may have to hold the keyboard down as you lift up on the display.

Note that the laptops in these figures are B2 units (B4 units have a dual-tone XO on the back of the machines).

Power on and power off

Power button

The Power Button is located in the bottom right-hand corner of the bezel surrounding the screen. The green power LED should come on immediately, but it takes approximately two minutes for the machine to boot. If, for some reason, you do not see text appear on the screen within 15 seconds, or if the machine does not power on at all, please see the #Bugs and or Known Issues Section at the end of this document.

Once the laptop is running, the Power Button is used for suspend. You must hold down the button for 10 seconds to shutdown the laptop. (You can also shutdown the laptop from the hover menu on the XO figure on the home view.)

Using the laptop

Home View

The laptop starts up on the Home View. Click to enlarge.

Features of the Home View include the XO icon; the network-status indicator; the battery-status indicator; and the Frame;

You can return to the Home View by hitting the Home Key (circle with one dot) or by clicking on the Home Icon on the Frame (as per below).

XO icon

Each laptop is assigned a color dyad that is used as an identifier throughout the interface.

There is a menu that appears when you place the cursor over the XO icon in the center of the screen. As of Build 542, this menu is only used for shutdown. It may be used for setting user preferences, such as colors, in the future.

Activity circle

The circle around the XO icon is used to display any activities that are currently running on the laptop. (In later builds, e.g., 547, the size of the sector is proportional to how much memory the activity is consuming. If the circle fills up, you will run out of memory.) The #Journal is always displayed at the bottom of the circle. You can resume an activity by clicking on its iconic representation in the circle.

Network status

The status of the wireless network is indicated by either a circle (mesh) or triangle (infrastructure) on the Home View. Details regarding connectivity are described below.

Battery status

The battery status is indicated by a battery icon. The icon fills with color from the left to indicate the current charge. Putting the cursor over the battery icon brings up more detail. Please note that the battery LED is illuminated when the battery is charging; it varies from yellow to green. Red is used to indicate that the battery is running low.

Frame

The Frame appears by default on the Home View. (It does not appear by default in any other view.) You can toggle the Frame with the Frame Key on the most upper-right corner of the keyboard or by moving the cursor to any corner of the screen (aka 'Hot Corners').

Upper-left icons (places)

• Circle with eight dots: This icon takes you to the #Neighborhood View, where you see network resources and the other users on the mesh network;
• Circle with three dots: This icon takes you to the #Groups View, where you see those users have identified as friends;
• Circle with one dot: This icon takes you to the #Home View;
• Circle with rectangle: This icon returns you to the #Activity View, where you resume work on the current activity.

Bottom icons (actions)

Different builds have different collections of activities. In Build 542, you should see:

• #BlockParty: a falling-block game;
• #Draw: a drawing activity;
• #Calculate:a calculator;
• #Write:a word processor;
• #Chat:a text chat program;
• #Etoys:a programing environment;
• #Browse:a web browser;
• #News':an RSS news feed;
• #Connect4:a Connect4 game;
• #Watch and Listen:a multimedia player;
• #TamTam:a music activity;
• #TurtleArt:a programing environment;
• #Record:a video capture activity.

Right-side icons (buddies)

The XO icons of the other people with whom you are collaborating show up on the right-hand side of the Frame.

Left-side icons (clipboard)

The left side of the Frame is for the clipboard.

Neighborhood View

Neighborhood View

From the Neighborhood View (sometimes referred to as the Mesh View), you can see who is present on the network, what activities and objects are being shared, and what networks are available. You can access this view by hitting the Neighborhood Key (eight dots) or by clicking on the Neighborhood Icon (as per above on the Frame).

Demo instructions

Patience is very important: the user interface does not yet tell you that it is busy starting activities, and we have just begun performance work. You are using alpha test software.

Demo Suite:

1. Web Browsing
2. Etoys
3. Memosono Game
4. Tam Tam
5. Dual resolution monitor
6. eBook and Camera
7. Chat

Home screen

Home view

After you turn on the laptop you will come directly to the Home screen.

To begin, bring up the Frame by pushing the “Frame” key on the upper-right corner of the keyboard.

The Network

As many demos use the network (browser, RSS feed, mesh demos), before you begin, the laptop should be associated with a network. The laptop should be able to access any wireless networks in the area.

Click on the network icon (five bars on the upper-right of the Frame). A list of available wireless networks will show up in a drop down menu.

If you cannot see any networks, it may be because the embedded control did not properly initialize the USB ports (the network controller is a USB device)—you will need to reboot.

Switching between activities

You can have multiple activities running at once—moving between them by returning to the Home view (key with one dot—) and then clicking on an activity that you'd like to go to.

Exiting Activities

To exit an activity, click on the Frame key to bring up the Frame.

Put the cursor over the activity icon at the top center of the frame and click on the X with the circle around it.

1. Web Browsing

Browsing

To launch the web browser, click the "globe" icon at the bottom-left-hand corner of the Frame; place the cursor over the icon and click the left button below the touch pad ONCE.

Type search terms into the Google search field or type URL in bar at the top of the screen.

Please note that currently, the web browser does not support Flash, Java or Chinese characters.

2. Etoys

Etoys

From the frame, click the shooting-star icon , ONCE. The Etoys activity will load and show a launch screen:

• yellow "demo": shows a "welcome demo" that will run in a loop. You can exit the demo by clicking "PREV" in the orange "Navigator" bar at the bottom left.
• orange "tutorial game": a nice tutorial to learn about Etoys "handles".
• violet "new project": start creating your own projects. Journal integration is still missing, but you can save your work to the MyEtoys folder by pressing "PUBLISH" in the orange navbar. There is extensive documentation on Etoys in the wiki (start here) and at squeakland.org.
• green "project gallery": Load example science and fun projects
• blue "load project": find a project on disk.

3. Memosono game

This is a memory game for two players. Winner matches the most images and completes his/her ice-cream cone on the right-hand side.

From the Frame, click on the icon that looks like a 3×3 matrix—.

Play game by giving each player a turn to click on pairs of blocks to reveal images with corresponding sounds. The object of the game is to make as many matches as possible.

4. TamTam

TamTam

From the Frame, click on the drum icon—.

Each picture on the right-hand side of the screen makes its own distinct sound. Click on the drum icons on the lower-right corner to set a beat for your composition. The far-right slider controls tempo of the drum.

Use the keyboard to play sounds at different pitches.

5. Dual-resolution display

These are instructions for demonstrating both the color and the black-and-white modes of the display from any activity. In black-and-white mode, with the backlight off, the screen is high resolution and viewable in sunlight; it is the most energy-efficient setting.

On the top row of the keyboard is a long button with different-sized solid circles.

The two larger circles control the B&W and color modes on the display.

• Pushing the largest circle (far right) puts the display into B&W mode.
• Pushing the second largest (second from the right) circle puts the display into color mode.

The two smaller circles on the left side of the button control the backlight.

• To turn off the backlight, press the smallest dot (on the far left) 12 to 15 times.
• To turn on the backlight, press the second dot from the left between 12 and 15 times.

6. Handheld mode (or eBook mode) and camera mode

When in this mode, keyboard and touchpad are covered, so only game controller buttons (which can be used for scrolling), camera, and microphone work.

• 

  Bring the display up to a 90-degree angle (and put the antennae down).

• 

  Rotate the display 180 degrees until it is facing backwards.

• 

  Lay the display down onto the keyboard.

• 

  Enjoy!

Using the camera

The camera can be used in ebook mode, but needs to be turned on in laptop mode: from the Frame, click on the eye icon—. Turn off the Frame and then put the laptop into ebook mode.

7. Chat

Prerequisite--sign onto Wireless network—preferably an open network that requires no authentication.

• Go to network view. (—Circle with 8 dots: This icon shows you the entire Neighborhood. Brings up all users available on the mesh network;)
• Add other XO icons as friends by selecting them.
• Open Chat application by clicking on balloon icon—.
• Return to network view
• You should see the XO characters as well as the chat activity
• Click on the chat activity
• Wait a minute
• Start chatting.

8. Write

9. BlockParty

This is a tetris-like game

10. Paint

This is an activity to make drawings and paintings.

13. Calc

Calculator activity has the classic functions (sum, subtract, divide and multiply).But also scientific functions (cos, sin, exp, etc)

Other HowTo's

How to see what programs are running

Turn on the Frame and click the circle with one dot in it at the top left hand corner of the frame or push that same button on the top row of the keys on the keyboard.

— Buttons from Left to Right: Neighborhood, Friends/Groups, Home, Back to Activity

Home screen will come up, but this time, icons that represent the programs running will appear in a circle around the XO logo. This is called the activity ring. When the ring is full you will not be able to start any more activities.

Click the icon to access that activity.

Bugs and or Known Issues

1. Keys that do not work

— Camera/microphone toggle key

— Grab keys (on either side of the space bar)

2. The laptop does not turn on

You must unplug the laptop and remove the battery.

Turn the XO over and move the button on the right side to the right. This will unlock the battery.

Move button on the left side to the left while lifting up the battery. Remove the battery and wait at least 30 seconds. Replace the battery and lock the battery in place. Plug the laptop back in.

Note that if you have completely discharged your battery, you will have to run the laptop without the battery—a bug in the battery-charge circuit prevents the charging of a completely dead battery.

3. The touch pad and keyboard are locked up

This most likely caused by static. Try the "four-finger salute": depress the four keys in the four corners of the keyboard (Fn, Esc, Frame, and Right Arrow). If this does not help, follow the instructions for restarting the laptop by removing the battery.

4. I can’t shut an activity down because the icon does not show up in the Frame

Try restarting Sugar by typing Ctrl-Alt-Erase. It should take about 30 seconds for Sugar to restart. If that fails, then try power-cycling the machine by pushing the power button. If all else fails, unplug the machine and remove the battery. Wait 30 seconds and then reinsert the battery, plug it back in, and power on.
