Important Interface changes due to prompt user feedback:
1. Picture chart has been increased in size.
2. Direction keys have been enlarged.
3. Default iPad screen timeout is now 2 minutes (user adjustable).
Lots of new features!
A contrast sensitivity function has been added. This is an extremely important aspect of visual testing and is almost universally overlooked because it requires specialised charts and is time consuming - not any more! This allows the contrast threshold at different spacial frequencies ("acuity") to be measured efficiently on a standardised distance chart. Log CS function added to iPhone5.
We will be validating this in a study to be performed at Fremantle Hospital.
User feedback has strongly suggested increasing the time before the iPad screen times out. An entry in the Settings app has been added (1,2,5 and 10 minutes). Be careful a bright chart on the iPad can drain the battery quickly!
User feedback has asked for additional charts/targets to be available. A Slideshow function has been added with 6 built in charts (cross cylinder, near chart [scaled for iPad mini if present], animated GIF, stereo-anaglyph, Worth 4 dot and Amsler grid). You can add your own slides (jpg,gif,png,bmp) by syncing over iTunes or email (emailed pictures must have the extension changed to '.eye'). User feedback on the usefulness of this feature is encouraged. Additional slides may be made available at http://www.idrs.com.au if interest is shown. The remote control function for the iPhone/iPad to control the slideshow is unlocked with the previous Pro upgrade.
The font for the picture chart has been updated to be less confusing.
iPad slider controls have been replaced by stepper controls for better fine-tune adjustment of chart parameters.
