Common Scenarios

CS1: Out of The Box (OOTB)

The user has just purchased the Talking Book device, opened the box, inserted the included batteries into the device, turned the power on, and listens to the “Welcome Message”.

CS2: Info/Help

The user does not remember how to find a particular recording. He listens to a message from the device to refresh his memory on the operating instructions. He can also hear the name of the currently selected content module, the currently selected page in that content module, and the any instructions specific to the module (e.g. the way a literacy exercise uses multiple-choice buttons).

CS3: Content Discovery (on device)

The user wants to find the content module of the micro-credit lending process on the device. She jumps through the content modules, listens to the beginning of each module title and skips to the next one until she finds it.

CS4: Listening to Content

The user turns on the device, locates the micro-credit application process descriptions, and starts to listen it using the device’s built-in speaker. When the room got too noisy, he plugs the earphone into the device and listens to it via the earphone. He is excited by the prospect of getting a micro-loan, and wants to tell other villagers about it —- he gathers them in the village’s open meeting area, and uses the Talking Book device to broadcast FM signal to a radio with a well-powered and loud speaker so that the whole group can hear the recording.

CS5: Recording Simple Content

The farmer wants to record and publicize a new fertilizing schedule of maize that he has used successfully last year. He estimates that he needs to speak for about 15 minutes to fully describe the method. He will describe the new method in 3 sections: (1) Summary of the new vs. old method (2) Benefits of the new method (3) Detailed step by step explanation. He checks his Talking Book device to make sure it has sufficient memory available for at least 15 minutes of recording. This is a simple content module in the sense that although it contains segmentation by chapters, it does not contain audio hyperlinks or interaction questions to the listener. In the process of recording, he can choose a particular chapter or the entire module, and either erase it or overwrite it by recording a new segment.

CS6: Recording Complex Content

Complex content are audio module that involves audio hyperlinks or interactive audio content. The basic Talking Book devices will not need to handle this scenario. At this point, let's plan on a computer being required to record complex content; although we may later have a deluxe Talking Book device that can record complex content.

CS7: Distribution of Content from Computer to Device

An NGO has collected the latest and best local maize farming methods, and has a comparison of the pros and cons of the 3 major types of fertilizers used by farmers in the region. The NGO wants to publish and distribute these 2 major pieces of information via the Talking Book system to all the villages in the region. A member of the NGO staff first uses a PC to record onto the PC, then she copies the audio content from the PC to a Talking Book device. She uses the device to check the recording.

CS8: Preloading Content onto Many New Devices

A thousand Talking Book devices have been manufactured. The standard set of audio content is being copied to all of the devices.

CS9: Copying Content onto 1 Device to Many Devices

See scenario (1) in section Information Scenarios.

CS10: Distribution of Content through Village Kiosk

The user of a Talking Book device discovered and is interested in 2 content modules on the Talking Book kiosk in the village. He copies them onto his device.

CS11: Distribution of Content from Device to Device

There will be many situations when one wants to copy content from one Talking Book device to another one. For example, a farmer who has copied an explanation of the local loan application process, upon visiting a friend in another village might want to copy the content onto his friend’s device so that his friend can also listen to it, and perhaps let the others in his village know about the loan availability and application process.

CS12: Distribution of Content from Mobile Phone to Device

The local NGO has set up a toll free telephone number for users to call in for healthcare information. The local village leader has a cell phone and uses it to call in for the information. He uses the phone’s earphone to connect to the Talking Book device and record the information onto the device (in real-time).

CS13: Distribution of Content by Radio

The debate between the 3 candidates for the upcoming November presidential election is being broadcast on radio. The user records the pre-debate election process information and the actual debate onto the device.

CS14: Automatic Shutoff and Resuming Content

The user is interrupted during a listening session, paused the playing of the recording, and went off to the next room and did not return for more than 5 minutes.

CS15: Power

a. Replacing non-rechargable AA, AAA, or D
b. Charging rechargeable battery at kiosk

CS16: Device Status Indicators

a. On/Off Indicator Light
b. Mode of Operation Indicator Light: “idle”,“playing”,“paused”, “recording” from microphone, another device or PC.

CS17: Updating Talking Book Device Software

Should this be a feature at all? In other words, should this be needed, or should the device be designed to be similar to a CD player in the sense that no software update in the field is expected?
