Operation with gloves made of latex or without
In several test series, commercially available rubber gloves made of different materials were tested and the projected capacitive touchscreens react perfectly with latex as well as with gloves without latex.
Self Capacitance vs. Mutual Capacitance
Both sensor methods, i.e. self-capacitance systems and mutual capaticance, enable the touchscreens to be operated with thin gloves and conductive pens.
For outdoor kiosks as well as in the field of heavy industry, Interelectronix only recommends the Self Capaticance System to enable the operation of the PCAPs with thick gloves.
A disadvantage of self-capaticance systems, however, is that the multi-touch function with this technology can only be realized with a few sizes.
Mutual Capacitance
Mutual capacitance systems have a much higher density of interpolable electrode information and thus have a more precise touch detection technique. This results in significantly better multi-touch functionality. However, entries with winter gloves or thick gloves are not possible.
Self Capacitance
Self capacitance systems, on the other hand, can be set to operate both thin and thick gloves. However, it must be noted that with a projected capacitive touchscreen that is designed for simultaneous operation using both glove thicknesses, you have to reckon with limitations in precision.
An optimal multi-touch function is almost only possible with the mutual capacitance system, which, however, excludes operation with thick gloves. In the meantime, however, special conductive gloves are on the market that enable the multi-touch function on mutual-capacitance systems.
