Human Object Interaction Detection System by Disney

Disney is working hard in Technology field, developing new techniques to interact with things around us in different ways. Now its time to move one step ahead to play with a stuff around us with a whole new experience.

Disney Research team directed by Dr. Alanson Sample showed that the
radio frequency signals transmitted by the radio frequency identification (RFID) tags, provides a unique RF
signature which can be used to determine whether a tagged item was being
touched or moved.

The researchers found that with their system ID Sense, they could
simultaneously track 20 objects in a room. It can also determine four classes of
movements with 93 percent accuracy.

“An effective means of identifying
people’s activities in their homes, schools, and workplaces has the
potential to enable a wide number of human-computer interaction
applications,” said Disney team member Alanson Sample.
“Whether it’s reading a book to a child, cooking a meal, or fixing a
bicycle, the objects that we use both define and reflect the activities
we do in our daily lives.”
This is not a new thing to attach wireless sensors to objects, but due to the size of the sensors,
their relatively high cost and the need for battery replacement has
limited their applications. RFID tags, as compare to other wireless sensors, are commercially
available technology, cheap and easy to apply to a wide range of
everyday objects.

They found that ultra high frequency (UHF) RFID tags, which can return signals up to 10
meters, by observing changes in the signals emitted by
the tags – received signal strength indicator (RSSI), radio frequency
(RF) phase and Doppler shift – they were able to make inferences about
the object to which the tag was attached.

Disney team explained on how ID Sense could be used by applying RFID tags to
stuffed toys, enabling an interactive story telling game. They used ID Sense to monitor 10 commonly used
items, such as a drinking glass, a milk container and a cereal box, to
show how information about daily living activities could be gathered,
and they showed that the tags could be used for studying the browsing
behavior of consumers in a retail store. Detecting occupying of seats or,
in security scenarios, detecting the opening and closing of windows and
doors can be done.
