A variety of types of conditions can be employed. Conditions use data to determine when an intervention will be delivered. Some interventions have expectations of the frequency of use. Frequency refers to the frequency with which any intervention is deployed. User defined workflows allow the user access to all intervention elements and content, permitting the user to decide the sequence and timing of their use. Below we describe common examples of workflows (user defined, frequency, conditions, tunneling). The workflow identifies when an intervention is delivered and potentially also the sequence of interventions. The workflow defines when and under what conditions BIT interventions are delivered and can take into account changes in the aims, elements, and/or characteristics that occur over the course of a treatment. That is, within our terminology, most BITs are intended as a treatment consisting of a series of interventions. Most BITs are designed for repeated interactions over an extended period of time. It is beyond the scope of this paper to provide guidance on the methods one might use to decide which attributes best meet the needs of users, as these questions are the subject of entire fields of study such as human factors engineering and human computer interaction (HCI). Conceptually, the elements could be considered objects, and the characteristics could be considered the potential attributes of those objects. The characteristics in this model are intended to reflect the need to modify BIT elements. and aesthetics, where these characteristics are made more relevant based on individual user needs and characteristics.
