1. Torque vs. Displacement?

-What is the method that should be used to apply skin stretch?

What needs to be done? - make device II, be able to control the rotational distance and current going into the system. Also be able to record what torque is applied/what distance is applied and record the magnitude the user estimates.

2. Vibration vs. Skin Stretch- How to equate the two applications of haptic feedback

-What amount of vibration produces the same intensity using a specific amount of skin stretch? This is needed to equate the two methods, so that in future experiments, we can say confidently that some amount of vibration applied to the human is equal to some amount of skin stretch, and compare the two responses.

What needs to be done? - make a vibration device that can be applied to the user, and be able to record the frequency & amplitude of vibration- come up with a code that will record vibration applied and torque applied, perhaps come up with a user interface so that the subject can adjust what torque/distance of skin stretch is being applied. This will likely involve some sort of magnitude equality tests.

3. Vibration vs. Skin Stretch- Human Response: Stationary situations

-Use the two methods to give the same haptic feedback. Does one have a better response than the other? Probably not, but we need to do this test before we do the next one.

What needs to be done?-Come up with some sort of haptic interactive game/environment, using Maverick. Be able to record data, probably will need to re-design the skin stretch device so that it fits better on a human, and allows them some movement. Wireless tactor time?

4. Vibration vs. Skin Stretch- Human Response: Dynamic situation

-Use the two methods to give the same haptic feedback, but instead of a user sitting still, measure their response to the touch feedback while they are in a dynamic situation, whether is it running, or shaking, etc. This is the big test, that will provide valuable information on whether or not skin stretch is a better application of haptic feedback than vibration.

What needs to be done?-Will definitely need a wireless/mobile skin stretch device that can be placed on the subject's arm and allow them to move freely. Will need to come up with a dynamic situation/game that relates to the stationary task as well. Perhaps will need to build a dynamic device so that the dynamics are uniformly applied from subject to subject.

5. Vibration vs. Skin Stretch- Human Response: Distraction tests

-Obviously, if a person is in a very controlled environment, their response to haptic feedback will be better than if they are multi-tasking or distracted by outside noise. We could do another test to see how well humans respond to vibration and skin stretch when they are distracted. Hopefully, one will be better than the other, because in real life, it is highly unlikely that humans will be in such controlled situations.

What needs to be done? Research distraction testing, and how to gather the correct data/apply the right type of distraction.

So these are the main tests that I can think of that need to be accomplished. How to do them is further down the road. Each test will likely require more re-design and we will need to combine the mechanical device with some sort of virtual environment/situation to test in.
