CASAS Smart Home dataset – scripted activities, with and without activity errors

(Washington State University) These two datasets represent sensor events collected in the CASAS smart apartment testbed at Washington State University. In both sets of data, ambient sensor readings are collected while 20 participants performing five ADL activities in the apartment. This resource is valuable for designing and validating activity recognition algorithms. Further, this resource provides data for detecting errors that are helpful in assessing and intervening for functional independence. In the adl_noerror dataset, the five tasks are:

• Make a phone call.  The participant moves to the phone in the dining room, looks p a specific number in the phone book, dials the number, and listens to the message.  The recorded message provides cooking directions, which the participant summarizes on a notepad.
• Wash hands.  The participant moves into the kitchen sink and washes his/her hands in the sink, using hand soap and drying their hands with a paper towel.
• Cook.  The participant cooks a pot of oatmeal according to the directions given in the phone message.  To cook the oatmeal the participant must measure water, pour the water into a pot and boil it, add oats, then put the oatmeal into a bowl with raisins and brown sugar.
• Eat.  The participant takes the oatmeal and a medicine container to the dining room and eats the food.
• Clean.  The participant takes all of the dishes to the sink and cleans them with water and dish soap in the kitchen.

In the adl_error dataset, a scripted error is introduced. The errors are:

• Make a phone call. Error: The participant initially dials the wrong number and has to redial.
• Wash hands. Error: The participant does not turn the water off after washing his/her hands.
• Cook. Error: The participant does not turn the burner off after cooking the oatmeal.
• Eat. Error: The participant does not bring the medicine container with them to the dining room.
• Clean. Error: The participant does not use water to clean the dishes.
