Many, if not most, folks have access to the internet and can provide their input electronically, provided the study is designed to allow use of multiple platforms and methods. As part of a clinical trial I've been asked to join some cognitive studies on-line. However, the software allows only for touchscreen and apparently doesn't support Mozilla Firefox. A study whose design incorporates a range of input capabilities (e.g., touch, mouse, keyboard, phone) is more likely to achieve better results. As compared to in-person studies that require travel, overall costs for a well-designed on-line study should be lower. This obviously won't work for all people or all types of studies, but where it could work, greater deployment should yield good results.
