1. A method, comprising:
- detecting a change of a handheld computing device from a first starting spatial condition to a first ending spatial condition, wherein the first starting spatial condition and the first ending spatial condition are angular orientations of the handheld computing device relative to a reference; and
querying, via a logic circuit, an index associating a plurality of spatial condition changes with respective likelihoods indicative of user attentiveness to determine if the index includes an entry having the first starting spatial condition and the first ending spatial condition of the detected change, wherein a first plurality of the spatial condition changes of the index are associated with corresponding engagement likelihoods representing how likely a respective one of the first plurality of spatial condition changes corresponds to a user beginning to pay attention to a presentation on the handheld computing device.
