2. The science or study of skin markings or patterns; especially, those of the fingers, hands, and feet; also, such skin markings themselves.
3. The science of skin patterns, especially fingerprints.
dermiatrics
Someone who specializes in the field or study of the treatment of skin diseases.
dermoglyphics
The study of the whorls and loops and arches in the fingertips and on the palms of the hand and the soles of the feet: "There are criminologists who specialize in dermoglyphics in order to have greater accuracy with their criminal investigations."
diacoustic (s) (noun), diacoustics (pl)
The science of spreading or bouncing sounds around: "Carson was an expert in diacoustics and was researching the qualities of surfaces that refracted or diverted sounds in different directions."

domotics, domotic
The application of "intelligent" technology to make a home more comfortable and convenient.

There is still no consensus as to the etymology of domotics. One definition says it means: blending of Latin domus, "house", with robotics.

Additional sources (www.domotics.com, www.answers.com; and others) state: "The term domotics is a contraction of the words domus (Latin = home or house) and informatics (= the science concerned with the collection, transmission, storage, processing, and display of information)."

Some of the applications under the heading of domotics are sensors that automatically adjust lighting levels to meet the personal preferences of family members.

Other sensors may be adjusted to water plants according to need or vary the ventilation to make best use of outdoor climate conditions.

If there were a fire or break-in, the domotics would be able to call emergency services and explain in detail what is needed.

Some experts have described clever fridges that can read the wireless tags on food, determine when items are getting low and automatically reorder them. “Intelligent” washing machines will decide how much cleaning the garments should have.

On a daily basis, domotic systems are often supposed to be able to automatically gather data from several sensors and do such things as adjust lights and music to the personal preferences of each member of the household, as they come into or leave a particular room.

What happens when more than one person is in the room and each one has a different preference?

Currently the most simple systems require that each person must wear a marker; such as, an RFID (Radio Frequency Identification) tag, while the more sophisticated ones detect movement, body heat, and other individual characteristics.

Again, how will even the most sophisticated systems handle multiple preferences from a family or social group?

drastic (adjective), more drastic, most drastic
Pertaining to something which is influenced in a strong, significant, and extreme way: Greg had to take drastic measures in saving money so he could continue making payments for his car.
