1. A method, comprising:

  • obtaining data from an orientation sensor and a position sensor with an attentiveness detector in a handheld computing device;

    determining an orientation change of the handheld computing device from a starting orientation to an ending orientation based on the data, the starting orientation and the ending orientation being angular orientations relative to a first reference orientation as determined by an orientation detector;

    determining a position change of the handheld computing device from a starting position to an ending position based on the data, wherein the position change occurs at a same time as the orientation change, the starting position and the ending positions being positions relative to a user;

    querying, via a logic circuit, an index associating a plurality of spatial condition change combinations with respective likelihoods indicative of user attentiveness to a presentation on the handheld computing device to determine if the index includes an entry having both the determined-orientation change and the determined relative position change; and

    determining a likelihood of attentiveness of the user to the presentation based on the entry.
