1. Reaction speed A certain amount of time passes between the moment the light spot falls on a character and the beep indicating that the character has been accepted This delay makes it possible to take the shortest course to the next character without the intervening characters reacting to the passing of the spot This reaction speed can be adjusted very simply For optimal comfort it is important that the reaction speed is chosen not too large and not too small The two step like symbols on the TA C MEE keyboard overlay are used for setting the Reaction speed is now 21 reaction speed The current setting is indicated on a small screen as soon as 1 you aim the pointer at one of these alll Increase speed symbols and the LUCY program is active The LED behind return 1 will blink as a sign that LUCY is waiting for input By aiming the indicator at one of the Select Return to continue y symbols the reaction speed will change step by step In a Decrease speed As soon as the desired value is reached you can consolidate it by aiming the light spot at the return symbol The correct setting can only be determined in practice because it varies from case to case In most cases a suitable start value is 17 If one chooses the setting higher the characters will react more rapidly to the light spot and a higher speed can be reached However the chance of errors occurring will increase Certainly in the beginning it can be rewarding to exp

3. 2 1 CONTROL METHODS continued Step by step selection Step by step selection by means of one or two control switches makes minimum demands on the motion ability of the user In nearly all cases with only a very small motility a solution can be found with switch control The disadvantage is the relatively low speed Before deciding for this solution it is recommended to try other control methods first Two switch With this method two switches are used to control LUCY The first switch serves to select one of the rows the second switch is used to select the character within the row Each time the row switch is pressed the next row of lights will light up When the desired row is reached the lights within this row can be switched on one by one by pressing the character switch repeatedly As soon as the desired character lights up pressing the row switch again will send the character to the computer One Switch With the use of a simple switch for the control of LUCY the LEDs behind the characters light up automatically row after row After activating the switch as soon as the desired row is lighted each E character in the selected row will light up sequentially By activating the switch again as soon as the desired character lights up this character will be sent to the computer 2 2 CHOICE OF KEYBOARD OVERLAY There are two types of keyboard overlay available Overlay no 1 is intended for direct selection with laser poin
