Computer/Human Interaction Spring 2012 Northeastern University1 MBTA Transport Assistance Nanda Kishore Bhat (Fall '11), Serkan Okur (Sp '12), Quazi Farhan (Fall '11) CCIS, Northeastern University
Computer/Human Interaction Spring 2012 Northeastern University2 The problems Unnecessarily waiting for MBTA transportation vehicles Lack of application with good user interface (HCI) Lack of application with older adult friendly user interface (HCI)
Computer/Human Interaction Spring 2012 Northeastern University3 Motivation Introduced on Piazza by Prof. Intille Evaluation of current similar applications –Lack of HCI approach –Lack of older adult concentration Usability of the concept Potential for backend implementation
Computer/Human Interaction Spring 2012 Northeastern University4 Surprise(s) Mainly by ethnography and prototype testing Familiarity of older adults to smart phones and applications
Computer/Human Interaction Spring 2012 Northeastern University5 Surprise(s) Interest issues of older adults on the subject We were definitely NOT our users (!) Expectations from the application
Computer/Human Interaction Spring 2012 Northeastern University6 The best today Covering only a particular line Are not designed with HCI concept Are not specifically concentrated on older adults Too complex
Computer/Human Interaction Spring 2012 Northeastern University7 Innovation Easy to use. Covers all T lines (except Silver T) Not too many interfaces Designed based on HCI concepts Focusing on older adults Tested on and improved by target users

Computer/Human Interaction Spring 2012 Northeastern University17 Tricky programming problem Final (Result) Screen v7.0
Computer/Human Interaction Spring 2012 Northeastern University18 The future Final Screen –Could span to multiple scheduled T’s –Programming challenges Including the bus stops –Could include bus stops and bus timings –Deadline restrictions
Computer/Human Interaction Spring 2012 Northeastern University19 The future Including text box input –Could also include auto-refill text-box input –Deadline restrictions Reminder for selected buses/T’s –Future result page could include reminder feature for each item –Deadline restrictions
Computer/Human Interaction Spring 2012 Northeastern University20 The future Handling Internet Connection deficiencies –Could still predict the arrival time depending on previous data or timely schedule –Deadline restrictions. Designing the horizontal view of screens –Could also implement the horizontal views of screens on smart phones –Deadline restrictions.
Computer/Human Interaction Spring 2012 Northeastern University21 Future process More ethnographic research Evaluate programming feasibility Select better platform & environment Adding functionalities iteratively Thinking simple More testing
Computer/Human Interaction Spring 2012 Northeastern University22 MBTA Transport Assistance Gives the real time information of when the next train will arrive to a specific T-station. It solves the inconvenience of waiting times for T’s (and possibly buses) with a better and easier interface that can be used without prior mobile experience. (especially for older adults)
