Technology - Constraints Processing intensive Audio CODEC – compress/decompress Bar coding - encode /decode w/error correction Image Processing • Not an out-of-the-box proposition • Optimization is key: Performance went from ~ 10 seconds per frame to 10 frames per second 15 Labels That Talk, Confidential

Technology - Constraints Manual positioning Depth of field Hand motion Off-normal and rotated (360 deg) Off-Normal, rotated Blurred due to hand motion Readable Not Readable 16 Labels That Talk, Confidential

Technology – Constraints - UI Audio “Warm/Cold/OK” Use by elderly Tone frequency, spectrum Intuitive user interface Playback of audio as Row of ten LEDs recovered (green, end one amber) Linear countdown during recording Keep-alive indicator Use for framing indication 17 Labels That Talk, Confidential

Technology - Opportunities DSP chips w/ software C cross-compilers Cell phone camera sensors Development environments Audio CODECs for cell phones Audio is fault tolerant 18 Labels That Talk, Confidential

Technology - Opportunities Bitrate Codec Company Notes License (kb/sec) Not the best quality, but Speex Open Source 1 -- 16 Open Source source is available Very good low bit rate quality, ComPacketer Compandent 1 -- 64 Proprietary Very slow Performance Proprietary or 4.75 -- Many codecs AMR VoiceAge build from 12.2 available scratch Proprietary Digital Voice AMBE 2.4 -- 9.6 Software or Systems hardware 19 Labels That Talk, Confidential

Technology - Problems Open Source Codec Labor intensive to port Minimal support Can be totally customized Commercial Codec Extra bits we don’t need Expensive 23 Labels That Talk, Confidential

Technology - Problems Image processing is hand-crafted Pattern recognition takes many forms No magic mathematical solution 24 Labels That Talk, Confidential

Technology - Problems Sensor chip manufacturers don’t always help One major company never responded Demo systems not complete 25 Labels That Talk, Confidential

Technology - Solutions Build PC test bed for CODECs Bar codes Image degradation simulation 26 Labels That Talk, Confidential

Technology - Problems Desktop Inkjet Printers Great variability in quality Will need to be certified “SoundPaper Enabled” Clogging – one missing dot matters Photo Kiosks Low resolution, may not be good enough May require a separate printer to print Soundpaper on back of photo 27 Labels That Talk, Confidential

Technology - Solutions Use machine-vision camera & SW for test Chip vendor support inadequate Buyout solution for demo schedule 28 Labels That Talk, Confidential

Technology - Solutions Multi-stage SW development Write to run on PC • Algorithms must be final due to effort required to port to DSP Rewrite for DSP constraints • fixed point • chip architecture Port to DSP • segmented memory • data pages through on-chip memory ASIC remains a possibility 29 Labels That Talk, Confidential
