Memory Protection

Be sure to keep separate copies of all important data by saving it on a computer hard disk or other medium. Note that all data stored in unit memory is deleted whenever batteries go dead. Memory contents can also become lost or corrupted due to malfunction and repair of the unit. Do not locate the unit in an area subjected to large amounts of humidity or dust. Doing so can create the danger of fire and electrical shock. Keep the unit away from food preparation area, stoves, and anywhere else it might be exposed to oil smoke or steam. Such conditions can create the danger of fire and electrical shock.

Location

Avoid unstable surfaces.
Never place the unit on an unstable surface, on a high shelf, or in any other unstable location. Doing so can create the danger of the unit falling and causing personal injury. Keep the unit away from ATM cards, credit cards, and any other magnetic card during transport and storage. Magnetic force generated by its speaker can render magnetic cards unusable. Keep the unit away from televisions and other radio wave receivers. Magnetic force generated by its speaker can cause interference with radio wave reception.
Rechargeable Battery Pack Danger
Never try to take apart the battery pack or modify it in any way. The battery pack has built-in safety and protection mechanisms that ensure safe operation. Damaging these mechanisms creates the danger of fire, smoke emission, and explosion. Never allow the positive (+) and negative () terminals of the battery pack to become connected by metal. Never transport or store the battery pack together with a necklace, hairpins or other metal objects. Doing so can short the battery pack, which creates the danger of fire, overheating, and explosion. Never use or leave the battery pack next to open flame, near a stove, or any other area exposed to temperatures of 80C/170F or greater. Doing so creates the danger of fire and explosion. Never charge the battery pack near a stove, under direct sunlight, in an automobile parked in the sun, or any other area subject to high temperatures. High temperature can cause the battery packs safety mechanism to operate making it impossible to achieve a full charge. Heat can also cause an abnormal chemical reaction, which creates the danger of fire and explosion. Never pierce the battery pack with nails, hit it with a hammer, step on it, or throw it. Doing so can cause internal shorting, which creates the danger of fire and explosion. Never use a battery pack whose exterior is extremely damaged or deformed. Use of such a battery pack creates the danger of fire, overheating, and explosion. Never use the battery pack with any device other than this product. Doing so can cause abnormal current that damages the battery pack and creates the danger of fire. Keep a battery pack that is emitting a strange odor or leaking fluid away from open flame. Fluid leaking from the battery pack is highly flammable. It creates the danger of fire and explosion.

Warning

Never expose the battery pack to direct flame, do not throw it into fire, fresh water, or seawater. Doing so can damage the built in safety and protection mechanisms, and cause battery fluid to ignite, creating the danger of fire and explosion. Should fluid from the battery pack ever accidentally get into your eyes, do not rub them. Rinse your eyes with tap water and then consult your physician immediately. If the battery pack does not achieve full charge after the normal charge time, stop charging. Continued charging creates the danger of fire, overheating, and explosion.

Batteries Warning

Never try to charge backup battery, take it apart, or allow it to become shorted. Do not apply solder to battery or expose it to heat, and never throw battery into fire or water. While the lithium battery is removed from the unit, take care to keep it in a place where there is no danger of it being accidentally swallowed. Be especially careful around young children. Keep batteries out of the reach of young children. If a battery is accidentally swallowed, consult a physician immediately. Should fluid from the battery accidentally get into your eyes, do not rub them. Rinse your eyes with water and then consult your physician immediately.
Misuse of batteries can cause them to leak, which damages and corrodes the area around the battery and creates the danger of fire and personal injury. Be sure to observe the following precautions. When loading batteries, make sure their positive (+) and negative () poles are facing correctly. Remove battery from the unit if you do not plan to use it for a long time. Use only battery types that are specified for this unit.

AC Adapter Warning

Never use a voltage that is different from that for which the AC adapter is rated. Also, do not plug the unit into a power outlet that is shared by other devices. Doing so creates the danger of fire and electrical shock. Never modify the power cord or excessively bend, twist, or pull it. Doing so creates the danger of fire and electrical shock. Do not allow the power cord to become damaged. Do not place heavy objects on the power cord or expose it to heat. A damaged power cord creates the danger of fire and electrical shock. Never touch the AC adapter while your hands are wet. Doing so creates the danger of electrical shock. Should the power cord ever become seriously damaged (internal wiring exposed or shorted), contact your original dealer or an authorized CASIO service provider to request servicing. Continued use of a seriously damaged power cord creates the danger of fire and electrical shock. Use only the AC adapter specified for this unit. Use of another type of AC adapter can damage the battery pack and create the danger of fire and personal injury.

Unplug the AC adapter from the wall outlet whenever leaving the unit unattended for long periods. Be sure to unplug the AC adapter from the wall outlet before attempting to move the unit to another location. Be sure to grasp the AC adapter when unplugging it from a wall outlet. Pulling on the power cord can damage it, and create the danger of fire and electrical shock. Keep the power cord away from stoves and other sources of heat. Heat can melt the insulation of the power cord and create the danger of fire and electrical shock.

Operating Precautions

The CASSIOPEIA is a precision digital instrument. Incorrect operation and rough handling can cause data storage problems and other malfunction. Be sure to read the following precautions to ensure proper operation. Charge the battery pack as soon as possible when they start to become weak. Continued use while power is low can lead to loss of memory data.
Do not leave dead batteries in the CASSIOPEIA for long periods. Doing so can result in battery leakage, which can damage the CASSIOPEIA and cause malfunction.
Use the CASSIOPEIA under the conditions listed below. Temperature: 0C to 40C (32F to 104F) No condensation Conditions other than those above can cause malfunction. Avoid using the CASSIOPEIA in areas subjected to the following conditions. Static electricity Extreme heat or cold High humidity Sudden temperature changes Large amounts of dust If you drop the CASSIOPEIA and damage it, immediately turn off power and contact your original dealer or an authorized CASIO service provider. Never continue using a damaged unit. Never place heavy objects on top of the CASSIOPEIA.
Never try to take the CASSIOPEIA apart. Doing so can cause malfunction.
Never insert foreign objects into connectors, slots, or other openings.
Take care to avoid spilling water or drinks on the CASSIOPEIA.
Use only the stylus that comes with the CASSIOPEIA to press the RESET button. Never use a pen, pencil, or other sharp writing implement. Doing so can scratch the touch screen and cause malfunction. Never use thinner, benzene, cosmetics, or other volatile agents to clean the exterior of the CASSIOPEIA. Use only a dry soft cloth or a soft cloth moistened with a weak solution of water and mild neutral detergent. Setting the display brightness too high or use of an optionally available CompactFlash card results in battery life shorter than that indicated in the specifications of this manual. Be sure to use the soft case to protect the display panel of your CASSIOPEIA while carrying it. Important! The TFT color LCD is a product of the latest color LCD manufacturing technology. However, virtually all TFT color LCDs have a very small number of pixels (about 0.01% of the total number of pixels) that do not turn on or always remain turned on. This is normal and does not indicate malfunction. Playing back movies, digital camera images, and audio files consumes large amounts of power and may cause the CASSIOPEIA to become warm to the touch. This is normal and does not indicate malfunction.

In such a case, you must change the setting so the COM port is always used as a serial port. See the documentation that comes with your computer for full details on COM port numbers and settings.

Using the AC Adapter

You can use the AC adapter to directly power the CASSIOPEIA or to supply power through the cradle. The battery pack charges while the CASSIOPEIA is directly connected to a power source by the AC adapter or while it is on the cradle. See page 29 for more information. s Direct Connection

s Cradle Connection

Warning Use only the AC adapter that is specified for this unit. Use of another type of AC adapter creates the danger of malfunction and bursting of battery.
Important Power also will not turn on if the main battery loaded in the CASSIOPEIA is dead. Long term use of the AC adapter can cause it to become warm to the touch. This is normal and does not indicate malfunction. Be sure to unplug the AC adapter from the power outlet whenever you are not using it. The AC adapter is designed for indoor use only. It should not be used outdoors.

Infrared Communications

The infrared port of this unit can be used to exchange data with another CASSIOPEIA, or with another device equipped with infrared communication capabilities. Remember that the two infrared ports must be pointed directly at each other when performing communications. The distance between the two infrared ports must be less than 30 cm. See the Palm-size PC Users Guide for full details on performing infrared communications. For infrared data communications with another device, the other device must conform with IrDA 1.0 standards, and it must specifically support infrared data communication with a CASSIOPEIA. Your CASSIOPEIA currently does not support IrCOMM communication with another device. The IrCOMM is equipped for communication that will be available in the future. Important Take care so either of the units does not move while infrared data communications are in progress. Infrared data communications may be impossible under strong sunlight or inverter type fluorescent lighting. Infrared data communication problems can be caused by the distance between the two ports, the angle between the two ports, outdoor sunlight, and low batteries. Dirt and dust on the infrared port surface can cause communications errors and other problems. Use a soft, dry cloth to wipe the port clean of dirt and dust. Disconnect the AC adapter from the CASSIOPEIA before starting infrared communication.
Using a CompactFlash Card

Your CASSIOPEIA supports Type I and Type II CompactFlash cards (3.3V). Important The card slot cover will not close when certain types of cards are in the slot. Remove the card slot cover and keep it in a safe place so you can replace it when you remove the card. Gently but firmly slide the card into place as far as it will go, but do not force it. Forcing a card can damage connectors. If you have problems inserting a card, pull it out and check to make sure it is oriented correctly. We strongly recommend that you store all unsaved data you are inputting or editing before performing this procedure. Sometimes, your CASSIOPEIA may not be able to detect a CompactFlash card. This is indicated when a program on the card does not start up normally. When this happens, remove the card, reinsert it, and then press the CASSIOPEIA RESET button. Your CASSIOPEIA supports 3.3V CompactFlash cards only. 5.0V cards are not supported. Use of an IO card that requires large amounts of power can cause the CASSIOPEIA to restart when CASSIOPEIA battery power is low. 1. Make sure your CASSIOPEIA is turned off.

ABSTRACT Decreased display size on PDAs and WAP phones may create usability problems when the user is engaged in inormation retrieval tasks, such as reading a long text document. The RSVP speed-reading paradigm for silent reading of on-line text was implemented on a PDA. Text presentation speed, character size as well as window width can be varied in the application. By linking scalable audio in the form of nomic or representational soundscapes that matches the content of the text appearing in the RSVP text presentation window at any reading speed, it might be possible to further enhance self-paced reading experience. Keywords RSVP, information retrieval, comprehension, PDA, speed-reading, on-line reading, Web, handheld computers, earcons. paper. The only difference is that instead of the text being parsed into paper page units, a scroll bar or turnpage keys are used for turning the pages. Turn-page keys are implemented in electronic books such as the Rocket eBook (2000). Reading text from paper is usually 20-30% faster than when reading the same text on-line from a large computer screen (Mills and Weldon 1987). Number of lines displayed (display height) does not affect reading speed largely whereas width does. Reading speed increased by 28% when changing from narrow one-third-screen width to full-screen width (Mills and Weldon 1987). Rapid Serial Visual Presentation, RSVP, dynamically presents text that is chunked into one or a few words at a time at a single visual location. This way of presentation eliminates the need for eye movements during reading. Juola et al. (in Mills and Weldon 1987) report that for equal reading rates, comprehension in the RSVP mode was similar to

INTRODUCTION

The readability of text presented on large computer screens has attracted a lot of attention during recent years. The present paper considers readability from a small PDA (Personal Digital Assistant) screen using the RSVP (Rapid Serial Visual Presentation) paradigm. The decreased display size creates difficulties when the user is engaged in information retrieval tasks, such as reading a long document (e.g., a novel) from the screen, which requires a lot of within page scrolling. A system and a method for adding sound to the silent reading experience are also proposed. 1.1
Static Versus Dynamic Text Presentation
The most common medium for text presentation is paper. The text layout is usually presented according to the same static metaphor on a computer screen as on
page mode comprehension. RSVP implementations for large screens are available on the Internet today (Cornix 2000, Vortex IV 2000). It thus appears that RSVP of long text documents (e.g., a novel) could be a good candidate when display size is small and the user is on the move and lacks printing facilities. 2 IMPLEMENTATION

soundscapes (coined by R Murray Shaffers) to appropriate passages in the text? Non-verbal soundscape earcons (Gaver 1986) are then played back to the reader when the text linked to it is displayed in the presentation window in the RSVP paradigm (Goldstein et al. 2000) at any selected reading speed (TimeFactory 2000) in order to enhance the reading experience.
A RSVP prototype, Reader 1.0, was implemented. Using PersonalJava the RSVP paradigm was implemented on a Casio Cassiopeia E-105 (figure 1). The Cassiopeia is a standard Windows CE based Palm PC. It features a small 4.5-inch colour screen with the resolution of 240 x 320 pixels (portrait mode).

Figure 2 shows the prototype interface of the RSVP Reader1.0. By the menu bar at the top of the interface the user can choose; type of text to display, the length of the text sequence shown at one time (text window width), the speed level at which the text is displayed (in 27 steps between app. 25-1000 wpm) as well as font size. Beneath the menu bar, information is displayed regarding the title of the text and the current settings regarding Length (17), Speed (level 3) and Font size (12 dpi). The text appearing in the presentation window is always aligned to the left. The application reads from the selected text file and presents text sequences that match the selected text window width. After punctuation delimiters in the text (., !, ?, :, ;), there is a blank text window (250 ms in duration) in order to improve comprehension. In order to enhance self-paced silent reading experience when interacting with electronic media, would it be possible to link non-verbal
