One of the main problems in the current version is the lack of control users have over the space. While Opinion Space has been kept deliberately simple to improve usability, giving users more control over the space has the potential to greatly increase both the user's personal investment in the space and the overall quality of comments generated by Opinion Space by allowing users to tailor the space to their preferences.
This is a mockup of the side-bar for the next version of the program. It lists the points displayed in the space in a linear fashion in order of proximity to the user, with the user's icon always at the top of the list.
In addition, it introduces the idea of groups and favorites (the buttons at the top), allowing the user to create custom sets of people and save them for later reference.
Finally, the system also introduces a search function, allowing user's to filter by a keyword.
Together, these new additions give the user a more flexible, powerful environment in which they can manipulate the space. It is now up to usability testing to reveal whether or not these new features and controls will in fact improve the user experience as well as the quality of ideas generated by Opinion Space.
