The following described system intends to provide ascreen reader for visually impaired mobile phoneusers. The novelty of the system is that it will workwith mobile phones which present a regular display(no touch screen).
There are three possible options all based on existingtechnologies for computers:
The first option is based on the use of a detachablereading pad and pen pointing device similar to theone utilized by computer users (graph tablet andstylus) (see fig. 1). In this case the reading pad repre-sents the display of the mobile phone. The pad needsto be big enough to fit to the different sizes of themobile phone displays that exist on the market. Thescreen reader device will be connected to the mobilethrough the data input (using data cable, IrDa orBluetooth). The reading area in the pad has to be ofthe same size as the display of the mobile phone. Soit will need to be calibrated each time the system isconnected to a new type of mobile phone with differ-ent size of screen.
Guiding frames can be sold separately for each mo-bile phone model to help the user to direct the penwithin the reading area. Also, if the user tries to readoutside the reading area, he/she could be warned byan auditory signal. The user will move the pen point-ing device to read the contents of the screen through avoice synthesizer. This is done by simple correlatingthe cartesian coordinates of the position of the pen inthe pad with the same position on the display. Then avoice synthesizer will output the information pre-sented on the display in that position. The voice syn-thesizer can be a part of the mobile phone or a part ofthe screen reader device although this will add bulki-ness to the product. In the first case the mobile phonewill need to have an additional provision of memoryto install the drivers.
The second option is to use a lightpen connectedthrough a data cable, IrDa or Bluetooth to the mobilephone (see fig. 2). Lightpens are pointing devicesable to read directly from the display of a computer.Once the section is determined where the®..
