Multi-User Interaction using Handheld
Projectors
by
Xiang Cao et al.
Ivan Elhart - ECE 992 Ubiquitous ComputingUniversity of New Hampshire 10/07/2008
Strengths A novel idea of multi-user interaction using
handheld projectors Each interaction technique is demonstrated
through pictures They provided a video
Their results are based on informal user feedback without statistical analysis
Weaknesses
Hypotheses could be more clearly stated Pictures could focus more on the interaction The tracking system and interactions could be
better explained Performance of the interaction using handheld
devices could be studied in different light conditions
To study how alignment and synchronization between projectors effects users’ experience
To have a system with a static projection and multiple handheld projectors which can explore the static image (for example Museum)

Shadow reaching: A New Perspective on
Interaction for Large Wall Displays
by
Garth Shoemaker et al.
Ivan Elhart - ECE 992 Ubiquitous ComputingUniversity of New Hampshire 10/07/2008
Strengths A new perspective on how shadows (real and
virtual) can be used as a user input
Results were based on informal observation of six first time users
Writing style could be improved• “When designing shadow-based interactions, certain choices
must be made.”
Weaknesses
Problems, goals, and hypothesis could be more clearly stated even though they were restated several times through the paper
When will inconsistent lighting and blurring cause problems?

Design of Human-Map System Interaction
by
Thomas Porathe and Johannes Prison
Ivan Elhart - ECE 992 Ubiquitous ComputingUniversity of New Hampshire 10/07/2008
Strengths Problem is efficiently introduced through real world
event (Norwegian high-speed ferry Sleipner) Laboratory experiment with two groups of users
• 45 amateur navigators• 30 Academy professionals
Statistical data analysis was performed and results were presented effectively on graphs
10x10 laboratory maze grid is far away from real world scenarios
Goals and hypothesis are not clear and they were restated several times
Weaknesses
Results could be explained in more detail with better conclusion
Order of the tasks and maps may effect results: specify how this was handled (randomized may not be ok)
