Call for Potentially Essential Patents
If anyone in this meeting is personally aware of the holder of any patent claims that are potentially essential to implementation of the proposed standard(s) under consideration by this group and that are not already the subject of an Accepted Letter of Assurance: Either speak up now or
Provide the chair of this group with the identity of the holder(s) of any and all such claims as soon as possible or
Cause an LOA to be submitted

“control of one's bodily motions,
the capacity to handle objects skillfully, a sense of
timing, a clear sense of the goal of a physical
action, along with the ability to train responses”
-- Gardner, 2011

• World of Repetition (that enabled long cycles of training to be cost-justified) … is gone!
• Short-run or personalised production (with advanced machinery and lower demand in physical dexterity) … is emerging!
• Learning Design Languages (Laurillard & Ljubojevic, 2011; Fuente Valentin, Pardo, & Degado Kloos, 2011; Mueller, Zimmermann, & Peters, 2010; Koper & Tattersall, 2005; Wild, Moedritscher, & Sigurdarson, 2008)
enable modelling of experiences, but fall short of Capturing and codification– Handling hybrid (human-machine) experiences
Context: Professional training

“verbs that refer to physical actions are naturally grounded in
representations that encode the temporal flow of events“
-- Roy, 2005:391
Verbs of handling and motion

• Specify force dynamics (out of a limited set)• Specify temporal Allen relations
(A ends after B, A starts with B, …)• Specify valency (number of arguments, cf. Palmer et al., 2005)• Primitives are ‘movement’, ‘path’, and ‘location’ (Chatterjee,
2001)
Any higher-level composition can be traced back to these atomic relations
Verbs of handling and motion

General taxonomy across applications (Robertson and MacIntyre, 2009)
– ‘Style’ strategies: ‘include’, ‘visible’, ‘find’, ‘label’, ‘recognizable’, ‘focus’, ‘subdue’, ‘visual property’, ‘ghost’, and ‘highlight’ (p.149f)
– Communicative goals signified by these styling operations for visual overlays are: ‘show’, ‘property’, ‘state’, ‘location’, ‘reference’, ‘change’, ‘relative-location’, ‘identify’, ‘action’, ‘move’, and ‘enhancement’ (p.148)
Need to be complemented with workplace specific taxonomy (of handling and motion)
Communicative intent

Removed screw: returned screw to used parts bucket– Dependancy-based:
