Laptop/ Tablet Computer Considerations

With the advancement of technology and the increased durability of commercial and

personal laptops, the use of computers for communication devices becomes an attractive

possibility. With the development of many different brands of tablet computers this

customised option becomes even more attractive providing increased portability getting

close to that of a dedicated communication device. However there are many points to

consider if attempting to replicate the functionality of the ‘off-the-shelf’ A.A.C. systems. A

few of these considerations are listed below, however it is strongly recommended that the

document “Things to Consider when choosing a laptop for A.A.C.” (Appendix D - written by

Sandra Stewart & Sue VanDeLoo) be read to gain a comprehensive understanding of the

required considerations. This document is slightly dated but nevertheless provides some

very useful information.

How will the user access their device?

If switch access is required then an additional switch interface (and possibly the necessary

software) must be purchased. Switch adapted mice or keyboards can also allow a switch

user some access to standard laptop programs. These options will result in extra hardware

that needs to be mounted and therefore additional cables. Thus you will have to consider

mounting of the switch interface as well as the computer and switches. For Words Plus

software the Micro CommPac is a device that provides a switch/joystick interface plus an

external amplifier for improved voice output. If using Sensory Software programs then you

might consider Gewa’s Mini Amplifier with Switch Interface. This product can also be

purchased with an in-built Gewa Prog module for P.C. based environmental control.

Many of the current tablets and some laptops provide programmable application launch

buttons, which may enable easier access to some of the standard windows applications,

without having to locate and select icons.

If the person is a keyboard user then it is not necessary to have a touchscreen (this could

save significantly on cost) – however, if it is foreseeable that a touchscreen might be

required in the future then it could be wise to purchase a tablet (i.e. Fujitsu Stylistic) or a

touchscreen laptop (i.e. Toughbook) to keep your options open.

Keyboard users are not ruled out from tablets as they generally allow connection of a

keyboard, but again this may introduce an extra cable. Bear in mind that keyboard and

mouse additions may decrease the portability of the system as well as the available room

on a wheelchair tray top. Tablets, such as the Compaq, have a removable keyboard that

provides the ability to change from tablet mode to notebook P.C. mode with relative ease.

The Toshiba and Acer tablets can be converted from tablet to notebook mode by simply

swivelling the screen (shown in Figure 1).
