The author of the FIT-System is a scientist in Ergonomics and Human Factors Engineering. Contacting him will help you to understand and use the potentials of the FIT-System technique and to innovate and improve your field study: juergen.held@hfg-gmuend.de In analysis of human or animal behavior you often have to record diverse activities. For example in field studies of Human Factors, Ergonomics, Psychology or in Biology you have to observe activities like tasks, interactions, states, postures, positions, locations, motions or any other observational events. For documentation of your observations you need to record or store them with a time stamp. Your objective is a list or table of the observed events with their related time stamp of occurrence or observation. Therefor you may use traditional time study Apps of key-stroke or pre-defined button recording. But very probably you will experience a set of problems: - You can not design your own user interface of recording. - Instead you have to use a restricted predefined set of buttons or icons. - You can not adapt the user interface to the context and your mental representations. - You have to declare and fix the meaning of your buttons before recording starts. - Memorization or learning of the fix set of buttons limits your event categories. - You can not easily change or adapt your interface during recording. The FIT-System (Flexible Interface Technique) App is different because: (1) It allows you to design a recording interface graphically or pictorially. In using or designing graphic symbols, text or simply by using photographs of the observation setting you can reach a better performance in recording in terms of faster reaction time, less erroneous input and the management of a much more higher amount of event categories. (2) Using the FIT-System you not declare the meaning of your interface in advance. There is no such thing like first defining everything of your study and then realize during pilot observations to change and redefine it. Instead you can start event recording even with a blank screen as your interface. The signature or meaning of your input in the FIT-System is done afterwards. It is a kind of reverse notation where you can focus on the observational character of the data and not have to narrow your capacities because of enforced occupation with predefined operators of the App. In a field study of human or animal behavior you will often be confronted with the need of a relatively fine grain of analysis. Thus managing more than 10 activities and 10 states or locations is often the use case. To solve this with traditional event recording Apps is problematic because of the given interface you have to accept. You will experience that most event recorders are quite a kitchen knife. While the FIT-System is more the versatile Swiss Army Knife tool. The result of the FIT-System App is a table of event data, i.e. the name or signature of the event and the time stamp in a table form. It can export to spreadsheet software as Numbers or Excel, or as a comma separated file (CSV) for use in statistical packages as R or SPSS. Your work with the FIT-System is supported by a iBook tutorial free of charge (see support link on this page). Additionally it provides you with recording examples and literature links. The FIT-System App is just a tool and free of in-App registrations or advertisements. If you consider to test the FIT-System free of charge, you will find a trial version "FIT-Basic" on the App Store. The trial version provides all functionality but restricts the number of event categories to twelve. Using the FIT-System you will stay "in touch" with the history of Apple Inc. as the FIT-System software derives from a first App written in the nineties for the touch screen of the "Apple Newton Message Pad" computer.

Wish you could have more time? Now you can! We save people just like you over 1 hour per day using Flexblocks! Flexblocks is an auto-scheduling app designed to optimize your day so you waste less time procrastinating. Here's how it works: When you have something to get done with a start and end date it goes in your calendar, and you're extremely likely to complete it, but tasks that have deadlines like your annoying math homework or physics lab don't, hence they go on to-do lists. The reason your math homework ends up being done right before the deadline is because you brain needs to see time set aside.. Introducing Flexblocks! Flexblocks fixes this problem by instantly scheduling timeblocks for you to complete these tasks before the deadline. Unlike any other apps, we learn what times work best for you to create the perfect schedule everytime! ------------------------------- We would love to hear feedback about the app. If you have any questions or concerns please reach out via any of the channels below: Instagram: @flexblocks Email: admin@flexblocks.app Notes: At present, all of our plans are paid because as a business we need to be able to pay the team to continue adding incredible features to improve your experience. The student plan is discounted significantly to allow all students access to this incredible software. Improvements to the auto-scheduling feature, calendar integrations, and re-occurring events are coming in the VERY near future. Current use at this stage in the development will enable us to bring these features to market much faster.
