Golsteijn, C., et al. (2015) “VoxBox: A Tangible Machine that Gathers Opinions from the Public at Events”

VoxBox is presented as an alternative way of gathering public opinions without ruining people’s pleasant experience. It is a tangible system for gathering opinions on a range of topics through playful and engaging interaction. This paper discusses the design principles employed in the VoxBox and show how they encouraged wider participation, by grouping similar questions, encouraging completion, gathering answers to open and closed questions, and connecting answers and results.
VoxBox tried to gather detailed feedback in crowd at fairs or festivals but still provide playful experience. Existing approaches were to have big display incorporated with mobile technology like texting or tweeting. However, some people found it unpleasant and self-conscious which led to the finding that people actually prefer interacting directly with the device. Also, there were some problems with existing approaches that people do not notice whether the display is for public voting or even though they notice it is, people did not easily figure out how to work with it. For the alternative approach, both curiosity and clear affordances are important. In this light, researchers have designed very simple physical button-based voting boxes for gathering opinions. Each module used a different input mechanism that people were familiar with and knew how to use, such as sliders, buttons, knobs, and spinners. The first module asked closed questions about demographics, the second about their current mood, the third about the crowd, the fourth about the event, and the fifth and final asked an open question. In addition, the system included a transparent tube at the side that dropped a ball step by step as the question modules were completed as an incentive for completion and progress indicator. Finally, the reverse side of the system showed three real-time visualizations of the collected data on small screen embedded in portholes.
The great point of VoxBox is that it grouped similar questions and encouraged completion by showing progress. They made real-time assessment visible to users and this information was organized and put easy from the users’ eyes.

O’Hara, K., et al.(2014) “Touchless interaction in surgery“

The issue of sterility is always important during surgery. As the surgical technology has been incorporated with various technology such as visual and machinery control via motion, maintaining sterility got harder and caused in delay during surgery. For example, when surgeons wanted a hands-on control, they had to remove gloves and rescrub. So this paper suggests the approach of having touchless interaction in surgery using gesture.
Beyond demonstrating technical feasibility, touchless interaction in surgery should be designed to work within operating-theatre practices. Gesture design should consider not only individual interaction with medical images but how they are used in the context of collaborative discussion. Gesture design across one and two hands should accommodate expressive richness, as well as the surgeon’s hands, but is constrained by the close proximity of the surgical team and movement restrictions due to sterile practice.
