Had these questions from many days. Though the question may be silly sort of thing for some of you here, i couldn't find a suitable answers in the Google. Moreover, fellow members here recommended me to open a thread, so that we can have a discussion on it.
The question is about Tacᴛɪʟᴇ Sensors(ᴛouch Sensors)... These sensors are used in most etouch gadgets nowadays. I couldn't find an article that can give info abt Tacᴛɪʟᴇ Sensors, so any links about the topic will be appreciated.
I have some questions about these sensors:
Q1: Why(and How) are some(iPads/Laptop Touchpad) of these sensors sensitive only to to human hand/skin? How do they work so?
Q2: When i use both my hands to these sensors (simultaneously) then there is no change in the cursor movement? Why is this so?
Q4: Some sensors that i've seen, require change in contact(maybe both direct/indirect). Ex: If i keep touching the transducer(touch sensor), and another person touches me and releases his hand. This causes Touch Switches ON/OFF, even though i dont to the work(instead another person does it for me indirectly). This happens even dirctly: i mean, me touching and releasing my hand also makes the switch work.
Q5: Some of them wont work without the person touching(standing/ footrest on) the Ground. Why and How?
I want explanation for these/links where i can find some info abt these. Thanks in Advance.
