These two modes have different constraints. Mobile phone tests all use button
presses as responses. Many tests use a two-choice (YES/NO, LEFT/RIGHT) response
set, a few use numeric buttons. Some tests on the tablet are set up in the same
way, with screen button instead of the phone keypad. Others involve a tap on
part of the stimulus display, rather than on a separate button.
For the core battery, stimulus displays have to be able to fit on a small screen, which can be
as small as 96 X 52 pixels. They scale automatically to fit larger displays.
There are a few tests that are available only on the tablet (see below).
The platform we use most is the mobile phone,
with a standard numeric keypad. Most of the tests use a two-choice format,
with 4 used for LEFT or YES, 6 used for RIGHT or NO. The phone is held as
shown on the left, with the two thumbs over the 4 and 6 keys.
Any phone with Java ("downloadable
games") a screen at least 128 X 128 pixels, and a numeric keypad will run the core battery.
This means that even many older phones will work OK. This is a great advantage, if you want to run
tests on volunteers' own phones, as it means that many people will already
have a suitable phone.
If you need features like storing data on the
phone card, we can do this, but it means that you need a reasonably
up-to-date phone. This doesn't mean expensive - the phones we are
currently using are priced at under £100 in the UK for pay-as-you-go.
We generally supply packages configured for a
specific project.
The following tests are currently available for both tablet and mobile
phones. Click on the test name for a
description. Demos are available for several of the test. Instructions on
running the demo are in
the description pages.
You can still obtain the original PenScreen battery on the Apple Newton, and
used Newtons can still be obtained. This is a convenient and inexpensive route
for small research projects.
