Problem High-level solution Representative tasks Design evolution Description of UI and demo Final usability test Reflection on project

Problem: No tool for remote battlemat game play

Distance is an issue Cost of tokens, battlemat, etc. could be

prohibitive

Create web based battlemat system Replicate tabletop game System has battlemat backdrop

Place tokens on map

Move tokens

Draw on the map

Drag the map

Determine spell area

Exercised almost all the system functionality Most common tasks for a player or dungeon

master Most dependent on the clarity of the icons

and tool tips

Icon clarity and tool tips were the riskiest parts of the system

Alternative designs

Login first or battlemat first?

Battlemat that is full screen or within a frame?

Inclusion of cursor icons?
