2. In situ search for digital ink InkSeine : Ink + Seine -n: a fishing net -v: to fish with a seine = insanely cool ink search! InkSeine lets the user fish for useful information directly from ink notes. Fishermen catching salmon on the Columbia River using a seine. (courtesy Wikipedia)

3. Active note taking XLibrispen-based system for active reading (reading + critical thinking + learning) InkSeine combines pen-based note taking with searching, linking, collecting & sensemaking:

4. Core interaction pattern: Ink-Search-Gather Ink – excels at capturing users thoughts & ideas with minimum distraction from formatting issues Ink Search Gather

5. Ink-Search-Gather interaction pattern Search – digging through the file system on a tablet is really a pain Active note taking benefits from low overhead access to supporting materials & related docs Focus on personal search, but support Web as well Ink Search Gather

6. Ink-Search-Gather interaction pattern Gather – Make it easy to use what you find by pulling content directly into unstructured notes Thumbnail hyperlinks to documents Clippings from documents Queries that can be revisited later Ink Search Gather

7. Ink-Search-Gather interaction pattern InkSeine unifies these three elements in a fluid user experience that is integrated directly with inking Ink Search Gather

8. In situ search Leverage preexisting ink to initiate search No context switch to search app – stay in the flow No tedious copying of information to a search box Queries as first class objects, commingled with ink notes Flag some ink for search for later Visible and salient search history as part of notes Queries can be copied, pasted, moved, etc. Interleave inking, searching & gathering No barrier between inking / searching – note ideas while searching, side-by-side searching, span app boundaries for content gathering Tightly couple queries with application content Queries naturally persist in originating context Easy re-visitation of prior queries Results of queries become new content

9. Rich tradeoffs in cost structure of sensemaking Continuum of time cost – can defer at any point: 1 second: Capture thought I should search on this 5 seconds: Trigger search & see initial results list 10s: Open a document from result list, or drag result into notes 10s-30s: Inspect details of a few results Apply filters to results Add a word to the query Grab a snapshot from a short document Correct occasional reco errors – but Tablets reco is amazingly good! Longer: sufficient depth for common info needs; not mired by last 10% of complex queries that require full featured search tools Scroll through longer results lists Inspect result documents to see if they meet information needs Sideways searches based on Title, Date, or Author of a result
