Problem & Solutions

• In outdoor situations, a bite from an unknown source is frightening

• Knowledge of the nature of the bite creates informed decision-making & improved outcomes

• Current solutions:o VenomByte

Database based on name and locationo InsectIdentification

'Bug Finder' by propertieso BugGuide

Extensive, user-constructed database of bugs

Approach to Solution

Desire• Access anywhere• Internet connection not required• Intuitive mobile design• Quick access to vital data

Solution• Android application

o large, mobile userbase• Offline database

o quick access to (mostly) static data• Multiple ways to access data

o useful under multiple conditions

Usability Test Method

1. Pre-test questionnaireo Ageo Gendero General knowledge of bugs & snakes

2. Timed identification of animals using three approacheso Location & risk levelo Pictureo Animal name

3. Post-test questionnaireo Evaluated satisfaction & reaction to application

Usability Test Results: Problems

Problem Importance Effort to RepairConsistent trouble due to unfamiliarity with the accordion layout design

5 3Lack of consistency when selecting location by state vs entire country

4 2Not obvious that scrolling panels are scrollable 3 3Not understanding that results are returned in an ordered fashion

4 2Search by name is not aesthetically pleasing 3 5White on black color scheme is hard to read outdoors 5 1

Usability Test Results: ChangesFix most important problems:• Changed color scheme• Update to accordion

o color contrast, size, + and - markings• Made location setting consistent• Higher contrast on scroll bars & flash on loading

Other changes:• Help feature for new users looking for assistance• Automatically updating search results• Rating bar for danger changed to red X• Important text fields (indicating risk) are highlighted

Conclusions

As a result of BugBytes development:• Produced mobile app for Android devices• Users are informed about spiders & snakes• Tested interface serves the needs of the majority of users

Future work:•  Enabling compatibility with & storage of other databases•  Additional emergency functions
