XLibris—pen-based system for active reading(reading + critical thinking + learning)

InkSeine combines pen-based note taking with searching, linking, collecting & sensemaking:

Ink – excels at capturing user’s thoughts & ideas with minimum distraction from formatting issues

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

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

InkSeine unifies these three elements in a fluid user experience that is integrated directly with inking

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

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 Tablet’s 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
