Knappmeyer et al.(2013)ͰͷίϯςΩετͷఆٛ 13 Context is any information that provides knowledge and characteristics about an entity (a user, an application/ service, a device, or a spatially bound smart place) which is relevant for the interaction between the entities themselves and with the digital world. Context can be categorised as being static, dynamic and rapidly changing. ίϯςΩετͱ͸ɺΤϯςΟςΟͱσδλϧੈքͱͷؒͷ૬ޓ࡞ ༻ʹؔ܎͢Δಛ௃Λఏڙ͢Δ͋ΒΏΔ৘ใͰ͋Δɻ ΤϯςΟςΟɿϢʔβɺΞϓϦέʔγϣϯ/αʔϏεɺσόΠεɺ ·ͨ͸ۭؒతʹ݁߹͞ΕͨεϚʔτͳ৔ॴ ίϯςΩετ͸ɺ੩తɺಈతɺ͔ͭٸ଎ʹมԽ͢Δɻ
