METHODS AND APPARATUS TO DETECT USER ATTENTIVENESS TO HANDHELD COMPUTING DEVICES
First Claim
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 a first entry having the first starting spatial condition and the first ending spatial condition of the detected change.

Abstract
Methods and apparatus to detect user attentiveness to handheld computing devices are disclosed. An example method includes 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 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.

8. A method as defined in claim 8, further comprising, when the index includes the first entry having the first starting spatial condition and the first ending spatial condition of the detected change and the second entry having the second starting spatial condition and the second ending spatial condition of the detected change, aggregating a first likelihood associated with the first entry with a second likelihood associated with the second entry to form a measure of user attentiveness to the handheld computing device.

9. A tangible computer readable storage medium comprising instructions that, when executed, cause a machine to at least:
-
detect 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 query, 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 a first entry having the first starting spatial condition and the first ending spatial condition of the detected change. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. An apparatus, comprising:
-
a detector to identify a change of a handheld computing device from a first starting spatial condition to a first ending spatial condition, the first starting spatial condition and the first ending spatial condition being angular orientations of the handheld computing device relative to a reference; an index having a plurality of spatial condition changes associated with likelihoods indicative of user attentiveness; and a comparator to determine whether the index includes a first entry having the first starting spatial condition and the first ending spatial condition of the identified change. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24)
