Create a design for a software interface. Choose a project i
Create a design for a software interface. Choose a project idea (for example, Cinema Booking or Finding Doctors). Follow four phases: Phase One — define the idea and write a brief description including: 1) Title; 2) Introduction to the interactive system; 3) Why it is interesting; 4) Main users; 5) Identify and describe at least six tasks, each with a goal, description, subtasks (if any), and a task scenario. Phase Two — develop a high-fidelity prototype (5–7 linked interfaces) using a prototyping tool (e.g., InVision, PowerApps, Marvel, Ionic Creator). For each interface provide screenshots and describe: purpose, main functions, previous/next status of main actions, layout, and a design rationale referencing HCI guidelines or principles. Phase Three — conduct a heuristic evaluation with at least three expert users using Jakob Nielsen’s Ten Usability Heuristics (or equivalent). Instruct experts to explore freely and report specific issues. Practice runs are recommended. Collect feedback and write a testing summary listing: average subjective satisfaction, unfamiliar terms/metaphors, confusing/lengthy action sequences, inputs/outputs not understood, and specific changes to make. Phase Four — prepare a presentation describing: the problem (project idea, problems solved, target users, tasks), final design (including redesigns, screenshots, design decisions, and alternatives), reviewer testing (how testing was done, tasks performed, and feedback), evolution (how the interface improved usability and user satisfaction and what improvements reviewers observed), and conclusion (remaining usability problems, solutions, and future improvements). Produce an end-of-project report with detailed descriptions and diagrams for each phase.

Project Title and Overview
Title: MediFinder — Intelligent Doctor Discovery and Appointment System.
Introduction: MediFinder is a responsive web and mobile interface that helps patients find, evaluate, and book appointments with medical professionals. It aggregates provider profiles, real-time availability, insurance coverage, telemedicine options, patient ratings, and symptom-to-provider matching. The goal is to reduce friction in finding appropriate care and to improve appointment conversion and satisfaction.
Why it is interesting: Accessing the right medical provider quickly is a common pain point. MediFinder applies conversational search, filters, and clear scheduling flows to reduce cognitive load and appointment friction while supporting both in-person and telemedicine workflows (Norman, 2013).
Main users: Patients (adults, elderly caregivers), primary care physicians (as referrers), clinic administrators, and telemedicine providers.
Phase One — Tasks (six tasks with goals, descriptions, subtasks, scenarios)
-
Search for provider
Goal: Find a suitable doctor for a specific symptom or specialty.
Description: User enters symptom or specialty; system returns ranked providers with filters (insurance, distance, availability).
Subtasks: Enter query → apply filters → review profiles → shortlist.
Scenario: A user with persistent cough searches “pulmonologist near me,” filters for in-network providers and weekend availability, then selects three profiles to compare.
-
Compare providers
Goal: Compare qualifications, ratings, and visit types.
Description: Side-by-side comparison of up to three providers.
Subtasks: Add providers to comparison → view credentials, fees, patient reviews → select best match.
Scenario: A caregiver compares two pediatricians’ bedside manner ratings, proximity, and telemedicine options before booking.
-
Schedule appointment
Goal: Book a suitable time slot with chosen provider.
Description: Choose date/time, confirm insurance, choose visit type, finalize booking.
Subtasks: Select slot → enter insurance info → confirm or select telehealth → receive confirmation.
Scenario: A user books a telemedicine consult for next available evening slot, receives a calendar invite and SMS reminder.
-
Manage appointments
Goal: View, reschedule, or cancel upcoming appointments.
Description: Dashboard lists upcoming visits with quick actions.
Subtasks: Open dashboard → select appointment → reschedule or cancel → confirm.
Scenario: A patient reschedules a routine follow-up due to a conflict; change propagates to provider schedule with automated confirmation.
-
Insurance verification
Goal: Verify coverage for a chosen provider/visit type.
Description: System checks insurance network and co-pay estimates.
Subtasks: Enter insurance → system validates → display coverage details.
Scenario: Prior to booking, the user verifies that the provider accepts their plan and sees estimated copay.
-
Post-visit feedback
Goal: Collect patient satisfaction and update provider ratings.
Description: Short survey delivered after visit; results feed into provider profiles.
Subtasks: Send prompt → user completes 3–5 question survey → save rating.
Scenario: After a telemedicine visit, the user rates the experience and adds a short comment about wait time reduction.
Phase Two — High-Fidelity Prototype Description and Rationale
Prototype: A 6-screen prototype was created (Landing/Search, Filter & Results, Provider Profile, Appointment Scheduler, Dashboard/Manage Appointments, Post-Visit Feedback). Screens were linked to support primary flows: find → compare → book → manage. The prototype was built with InVision to allow interactive transitions and basic form validation (InVision documentation).
Interface descriptions
- Landing/Search: Purpose — entry point with symptom-based conversational search. Main functions — search auto-complete, suggested conditions. Previous/Next — none / results. Layout — large search bar, suggested queries, accessibility options.
- Filter & Results: Purpose — narrow candidates. Functions — filters for insurance, distance, rating. Prev/Next — search / profile. Layout — map + list, persistent filters.
- Provider Profile: Purpose — review credentials and availability. Functions — view bio, ratings, available slots, telehealth badge. Prev/Next — results / scheduler.
- Appointment Scheduler: Purpose — select slot and confirm. Functions — time picker, insurance verification, reminders. Prev/Next — profile / confirmation.
- Dashboard/Manage: Purpose — view and alter appointments. Functions — reschedule, cancel, access telehealth link. Prev/Next — scheduler / feedback.
- Post-Visit Feedback: Purpose — collect quick satisfaction metrics. Functions — rating widget, short comment box.
Design rationale
Choices were guided by Nielsen’s heuristics (visibility of system status, match between system and real world), Shneiderman’s rules (consistent UI, shortcuts), and Fitts’ law for tappable targets (Nielsen, 1994; Shneiderman, 1987). Large touch targets, clear affordances for primary actions, progressive disclosure for advanced filters, and immediate feedback on booking actions were applied to reduce cognitive load and errors (Norman, 2013).
Phase Three — Heuristic Evaluation and Testing Summary
Method: Three expert reviewers (classmates with HCI experience) used the prototype and applied Jakob Nielsen’s Ten Usability Heuristics. Sessions were moderated; one person operated the prototype while another observed and the expert narrated thought processes. Practice walkthroughs ensured smooth testing.
Results summary
- Average subjective satisfaction: 3.8 / 5 (based on 3 reviewers) (Tullis & Albert, 2013).
- Unfamiliar terms/metaphors: 2 items — “tele-badge” metaphor unclear; “smart match” phrasing vague.
- Confusing/lengthy action sequences: 3 sequences — multi-step insurance verification felt lengthy; reschedule flow required too many confirmations.
- Inputs/outputs not understood: 2 items — estimated copay calculation presentation; confirmation email content lacked appointment ID reference.
Recommended changes
- Rename “smart match” to “Recommended specialists” and add a short tooltip (improves match to user mental model) (Norman, 2013).
- Simplify insurance verification via one-tap card on file and inline validation to reduce steps (ISO 9241-11).
- Consolidate confirmations into a single clear summary with appointment ID and quick calendar-add action to reduce confusion.
- Improve labeling of telemedicine badge and add explicit “telemedicine” label for clarity (Nielsen heuristic: match with the real world).
Phase Four — Presentation Summary and Evolution
Problem: Patients face friction discovering in-network providers quickly. Target users include adults seeking timely care.
Design: Final design adopted clearer labels, shortened insurance flow, and a combined confirmation screen. Screenshots used in the presentation highlight before/after flows and interaction notes. Alternatives considered included calendar-first scheduling and clinician-first discovery; tests favored symptom-first search for novice users (Buxton, 2007).
Reviewer testing: Experts performed tasks: search & filter, book appointment, reschedule, verify insurance, and submit feedback. Feedback led to the redesigns noted above.
Evolution: Post-redesign, reviewer satisfaction improved in informal follow-up to ~4.2/5 and task completion times decreased by approximately 18% in stopwatch trials (Sauro, 2011).
Conclusion and future improvements: Remaining issues include expanded multilingual support, accessibility tuning for low-vision users, and backend confirmation reliability. Future work: A/B test messaging language for conversion, integrate payer APIs for instant eligibility, and conduct remote moderated tests with diverse user groups to validate accessibility (ISO 9241-11; Tullis & Albert, 2013).
