FIG. 11R is a chart illustrating the consonant phonemes in FIGS. 11K-11Q, and the mapping between the location, duration, and type of the haptic outputs corresponding to each consonant phoneme and the manner of articulation and place of articulation of each consonant phoneme, according to an embodiment. The row legend describes the different manners of articulation of the phonemes described in FIGS. 11K-11Q, while the column legend describes the place of articulation of the same phonemes. The manner of articulation is the configuration and interaction of the articulators, which include speech organs such as the tongue, lips, and palate, when making a speech sound, i.e., the phoneme. The place of articulation is the point of contact where an obstruction occurs in the vocal tract between an articulatory gesture (e.g., a mouth movement), an active articulator (e.g., a part of the tongue), and a passive location (e.g., the roof of the mouth). These apply to consonant phonemes.
In one embodiment, the location and type of the haptic output associated with each phoneme, as described above in FIGS. 11K-11Q, have a relationship to the manner of articulation and place of articulation of that phoneme. Thus, the haptic outputs may be associated with the phonemes in a manner that adheres to certain rationale in order to create this relationship. These rationale are described below.
1) Consonant phonemes may be related to haptic outputs that are at a single point, such that no movement (e.g., shear) is sensed by the user due to the haptic output.
