Ideation results


In this blog post we want to present to you the results of our brain-storming process concerning our mobile interaction project.


We started off by brainstorming the general direction of our project. At first we settled on three different main directions that we were interested in: games, productivity tools and information display. The result of our brain-storming process can be seen in the following picture:


Next, we decided to think up different scenarios individually and share them with each other. Each team member was given three votes that they could cast on any scenario but their own. The votes had weights from 1 to 3 in order to express a preference towards a scenario. The following list sums up the scenarios the team members came up with:

  • Telemedicine – A large screen paired with a Kinect could be used in a medical context. One possible scenario could be a hospital admission, where the user is able to do the anamnesis on his own. The system could directly create a new patient file and find a suitable department (and possibly even a free bed), and enqueue the patient in the waiting line for a doctor based on the severity of his affection. Another scenario could be a platform for people living in third-world countries or rural areas where they can seek medical assistance for minor medical problems, without having to travel to the next big city.
  • Air terminal – At an airport the large screen could provider general information about departures. A Kinect sensor would recognize a person approaching the screen and switch to a personal assistance mode were the traveler is able to seek information specific to his flight, get directions or even self-check-in baggage. Even an assistance mode were a human operator could help the traveler via a webcam is thinkable.
  • Brain jogging & exercise – After a stressful meeting or a hard day of sitting in an office chair, office workers need a way to relax and revive. The large screen and the Kinect could be used to create some mini-games like memory to revitalize one’s spirits or mini-games like warm-up exercises for cardiovascular training after sitting all day long.
  • Air guitar hero – A Kinect-powered version of guitar hero would be the focus of attention at any party. Each player plays an instrument by just making the right motions.
  • Media library – The media library could manage all kinds of media including music, videos and pictures. At a party people could collaboratively create and edit playlists and families could sort, edit, and browse through the photographs taken at the last family vacation.
  • Quiz competition – A quiz competition between co-workers of different departments. Each department of a company could have a large screen were co-workers could play quiz games. At the end of each week the winning department will be elected. This could help bonding within departments and teams and also establish some friendly competition between different departments.
  • Starlit sky in the city – The large screen could be integrated in the roof of bus stops in large cities and display the current night sky view from the position of the bus stop. Because of light pollution in large cities the night sky, the stars and the milky way have almost become invisible. This could draw some attention to the issue and show the beauty of the night sky to city dwellers. People could even interact with the screen using the hand gestures and view thorough information about stars, nebulae and galaxies.
  • Flight simulator – The flight simulator would transform the player into a plane. The arms could be used as wings and by going up and down the altitude of the plane could be changed. Maps could be created collaboratively and players could create missions for fellow players, where they have to shoot enemies, collect items or fly to certain targets.
  • Collaboration software – By using the large screen as whiteboard for brainstorming and information sharing, it could be used as a portal for collaborating with distant co-workers and simplify working together even though being spatially apart.
  • CSI – The large screen coupled with a Kinect could be employed for storing, managing, and evaluating evidence and could thus be transformed into a central collaboration tool for crime scene investigators.

The following table presents the result of our vote:


Unfortunately there was a tie between CSI and the collaboration software. Therefore we conducted another vote with the final winner being the CSI scenario.


After settling on a scenario, we all started developing new ideas and evolving them together. We dubbed the project „C.R.I.M.E“, which stands for „Crime scene investigation Repository for Intelligence Management and Evidence evaluation“. The software can be used to create files for investigations. All findings will be stored as entities. These entities can be categorized as persons, evidence and locations. Persons could either be victims, suspects, informers or any other person that is somehow involved with the investigation. Evidence entities can be subdivided into evidence and circumstantial evidence. Locations can include crime scenes, residences or other locations valuable for the investigation. Each entity may hold arbitrary information (e.g. descriptions and pictures). Associations between entities may be established (e.g. an evidence entity may be associated with the location where it was found or persons could be associated with other persons in order to express some kind of relationship between them). Each investigation can also contain a timeline where the investigators can comprehend the sequence of events based on the evidence.

C.R.I.M.E will also contain other productivity tools for research and evaluation. Everything in the application will be controlled with the voice and gestures. An investigator could, for example, ask a question and the system would make a query on knowledge bases like Wikipedia or Wolfram Alpha. Tools like fingerprint matching will be integrated right into the application.

This collaboration platform will be the center of all investigations and could be located in a public room that all investigators have access to or in a meeting room, where all investigators may gather, share their newest information and feed it to C.R.I.M.E.

User profile

While developing the project idea we had to create a persona and identify our target group of people in order to find out what their motivations are and what they would expect from a tool like C.R.I.M.E. We called our persona „Sherlock“ and the following list of properties describes him:

  • Fears
    • Not being able to solve a case
    • Disappointing victims
    • Overseeing some crucial evidence or detail
  • Motivations/Aims
    • Wants to make the world a better place
    • Uses new tools and techniques to incorporate information and make his job easier, more efficient and more successful
  • Likes
    • Organizing things
    • Putting things into context
    • Problem solving
    • Collaborating with people from different professions to enhance the results
  • Dislikes
    • Not being able to bring justice to criminals because of a lack of evidence or a procedural error
    • Disorganization
    • Working through a pile of unorganized information
