Project Descriptiion Application domain

My Experience(toolkit)

Capture field data with a context aware platform

General prototyping and evaluation

ContextPhone(toolkit)

Provide context by simulating GPS General prototyping and evaluation; Pervasive computing

ActivityDesigner (toolkit + framework)

Consider real life activities as they play out over time in realistic locations

Ubiquitous computing

Trajectories(framework)

Consider how users move through space, time, activities, and interfaces

Augmented reality

#1: Start small and scale up the fidelity

Classification of Key Evergreen Trees in Utah

1. a. Leaves scaly-like; cones are small; blue and berry-like…………………………… go

to 2 b. Leaves needle-like; cones are large

and brown……………………………………… go to 3

2. a. Leaves rough; berry-like cones are about 1 inch in diameter; trunk is

forked………………….……………………………go to 17

b. Leaves smooth; berry-like cones less than 1 inch; trunk has central

stem…...Mountain Pine

#2: Focus on activities over interfaces

#3: Treat participants as co-designers

#4: Test in a representative space

#5: Respect authentic social experience

Future Work

http://biotracker.byu.edu

Prototyping Location, Activities, and Collective Experience over Time

• PLACE is an iterative, mixed-fidelity approach

• Researchers should scale up PLACE in accordance with their unique needs

• PLACE can be used with other frameworks or toolkits

• PLACE does not incorporate traditional usability testing
