1 Friday, December 2, 2005 Human Information Processing Personal Memex Virginia Tech Plans with SenseCam: Early Ideas Microsoft Memex Workshop, July 2006 Beyond Human Memory: SenseCam Use in Veterinary College and as Assistive Technology Manuel A. Pérez-Quiñones, Edward A. Fox

2 Friday, December 2, 2005 Human Information Processing Personal Memex Virginia-Maryland Regional College of Veterinary Medicine Context of student life at the Vet School Goals: –improve the recall of clinical procedures studied in lab sessions –promote learning through sharing of information among students which should result from integration of –audio/photos from multiple SenseCams, –video from the professor, and –live notes taken by several students Sharing: –Students will have the option of providing access to particular pieces of information by particular users. –Information will be uploaded automatically to a web server where it will be available to other students for download into their MyLifeBits data store.

3 Friday, December 2, 2005 Human Information Processing Personal Memex Students with Disabilities Help students with disabilities in their day-to-day activities on campus Use location tracking and some form of simple tagging of the audio or video data to help students with prospective remembering Allow students with motor disabilities to share data with their care-giver and/or with the staff of the Assistive Technologies office Track locations indoors with device

4 Friday, December 2, 2005 Human Information Processing Personal Memex TermVeterinary SchoolStudents with Disabilities Spring 2006 Early-semester - 2 students use SenseCam for week at a time Mid-semester - administer memory test; design and prototype data sharing functionality Late-semester - focus group, interview students Early-semester – identify students that will participate; consider privacy and legal issues Mid-semester – allow student to use SenseCam for a period of time. Design and prototype indoor route visualization. Late-semester – analyze effectiveness of SenseCam for students with disabilities Summer 2006 Implementation of new functionality into MyLifeBits schema. Write papers with early results, participate in workshops Fall 2006 Repeat memory study using new functionality. Consider collaboration and sharing of data more explicitly. Recruit new participants Deploy system with participants and care- givers Evaluate effectiveness. Publish results, participate in workshops Original Timeline

5 Friday, December 2, 2005 Human Information Processing Personal Memex Human Information Processing with the Personal Memex Ingrid Burbey, Gyuhyun Kwon, Uma Murthy, Nicholas Polys, Prince Vicent Human Information Processing Project Presentation

6 Friday, December 2, 2005 Human Information Processing Personal Memex Overview Literature Search: HIP Principles Initial Prototype Expert Interviews Cognitive Walkthrough with experts Scenarios Task Analysis Revised PrototypeDesign Guidelines 1. Project Overview Annotated Bibliography

7 Friday, December 2, 2005 Human Information Processing Personal Memex Overview Literature review Expert Interview Studies of current related systems Brainstorming Design Analysis Prototype& Evaluation Scenario generation Function decomposition Task decomposition Specifying interaction Low fidelity prototype Cognitive walkthrough Iterative analysis and design based on Usability claims and HIP principle 1. Project Overview

8 Friday, December 2, 2005 Human Information Processing Personal Memex Memex Prototyping Test Scenario Description Performing Cognitive Walkthrough Record usability problems found Fix the usability problems System Requirements HIP/Usability Principle Cognitive Walkthrough 1. Cognitive Workthrough Process

9 Friday, December 2, 2005 Human Information Processing Personal Memex Human Information Processing: Memory The Multi-Store Model (Atkinson & Shiffrin, 1968) Encoding, Storage, Retrieval

10 Friday, December 2, 2005 Human Information Processing Personal Memex Human Information Processing: Long-term Memory Types of LTM (evidence from Amnesiacs) –Semantic: Knowledge & Facts –Episodic: Events & Experiences –Procedural: Skill Aspects of LTM –Explicit aka declarative –Implicit aka non-declarative

11 Friday, December 2, 2005 Human Information Processing Personal Memex Human Information Processing: Long-term Memory Structure of LTM: Schemas –Developed by experience and pre-programming; accommodation & assimilation –Prototypical elements are always given priority –Can be applied non-consciously –Shared across individuals within a culture – Stable over time

12 Friday, December 2, 2005 Human Information Processing Personal Memex Human Information Processing: Long-term Memory Recall can be confounded by: Proactive interference – prior learning interferes with subsequent learning Retroactive interference – post hoc learning confounds the prior learning

13 Friday, December 2, 2005 Human Information Processing Personal Memex Human Information Processing: Long-term Memory Models of LTM retrieval Associative Memory –Levels of Processing –Cue-dependent forgetting Encoding Specificity Principle : Context !!! –Priming & Cues : visual, verbal, …

14 Friday, December 2, 2005 Human Information Processing Personal Memex Human Information Processing: Working Memory Working Memory, Baddeley, 2003

15 Friday, December 2, 2005 Human Information Processing Personal Memex Symptoms of Macular Degeneration Difficult to see colors Difficulty recognizing faces Prefer dim backgrounds

16 Friday, December 2, 2005 Human Information Processing Personal Memex Mild Cognitive Impairment Due to Hippocampus shrinking No universally, accepted definition Symptoms –Loss of short-term memory –Forgetfulness –Deteriorates over time –Difficulty in associative memory Remembering names of people or things

17 Friday, December 2, 2005 Human Information Processing Personal Memex Design Guidelines Formulated in the tradition of Nielsen, Tognazzini Discovered or confirmed through: –Literature search –Expert interviews –Cognitive walkthrough

18 Friday, December 2, 2005 Human Information Processing Personal Memex Design Guidelines General Results Maintain consistent, meaningful graphics Support opportunistic navigation –user control and freedom –Bookmarking paths, previous searches Leverage user recognition rather than recall –provide context for users while searching and browsing memories Provide visibility for mode & system status Provide Internationalized Tool Tips for icons and buttons Provide Help w/o loosing state Provide Tutorials explicitly demonstrating functionality

19 Friday, December 2, 2005 Human Information Processing Personal Memex Design Guidelines Population-specific Results: Mild Cognitive Impairment Simplify task steps Provide views that can represent time and objects graphically Provide time, space, and object reminders (for schedules, directions, medication)

20 Friday, December 2, 2005 Human Information Processing Personal Memex Design Guidelines Population-specific Results: Visual Impairment Provide enlargeable fonts & interface items (e.g., buttons) Provide contrast between font and background Provide options for audio output: voice, speed, pitch

36 Friday, December 2, 2005 Human Information Processing Personal Memex Tablet Idea Monday Tablet session Discussion that people aided by assistive technologies are delayed a long time before the right affordances arise Idea that SenseCam could be used along with a Tablet in synergistic capture, analysis, design, deployment methodology

37 Friday, December 2, 2005 Human Information Processing Personal Memex Summary and Conclusions Two planned efforts Student project report Tablet idea Looking forward to new version! Hoping Microsofts many projects (search, image processing, Tablet, etc.) can be inte grated with MyLifeBits Hope Microsoft staff can help run a JCDL workshop on personal DLs in 2007 Open for collaboration –
