| The Learning Route Management System (LBS) was developed for vocational education (in Dutch: MBO-onderwijs). Since the introduction of competence based education it became difficult for teachers to get insight into the educatonal progress of students. Learning routes became individual and assesments became more complex. Teachers are often not used to asses competence as well as practical results. LBS combines all aspects of an individual student and presents this in one diagram. Via automatic appllication of color coding for excellent (green) versus bad (red) results LBS shows the current level of a given student in one glance. LBS is in an experimental testing stage in one of the Dutch ROC's (conglomerate of vocational educations).

| The TSO-1000 is a large Oven that steams and/or cooks food products, primarily white meat and secondary red meat and ready meals, to a desired internal temperature at high load, optimum yield and cooking times. The new interface for this Oven is the start of the development of an interfacetoolkit for a series of products from Stork Food Systems. These Ovens are sold worldwide. Operating staff is often low-educated and many different languages are usually present within the staff of one factory. Therefore much effort was put into the design of a pictographic language combining basic pictographic elements. The HMI-design of the interface toolkit was a joint venture between Holslag vof and Human Efficiency in cooperation with the internal development staff of Stork Food Systems.

| The SpectraCell RA is the worlds first bacterial strain analyzer for rapid MRSA typing using Raman spectroscopy as the enabling technology. The machine analysis bacterial samples on testslides and compares the results to large amounts of previous samples gathered in a database. Medical staff can easily set up studies and investigate results. River Diagnostics developed the instrument, Dok Medical Design was responsible for the product design and asked Holslag vof to collaborate by designing the user interface. The SpectraCell RA prototype was first shown at Medica 2007 in Düsseldorf.

The PDA-program is a tool for all Dutch Syntensconsultants. It is used to analyse the productdevelopment of companies. The consultant asks a series of questions of various nature (multiple choiche, specify numbers, interact with graphical tools like sliders, etc). The userinterface is very flexible through fivefold redundancy thus giving optimum freedom in the sequence of the questionnaire. At the same time it is made very easy to see if an input is complete. The result is a comparison of the company's own expectations with reality (based on given answers) on several aspects of productdevelopment. After that the pda-tool can benchmark the investigated company with a choosen set of competitors (same business, same region, same size, etc). The exact detailed data is visualised on screen and figures and data are exported to files to give basis for a printed report. The specifications for the PDA-tool were set by ir. M.E. Swart and drs. D.A. Hoeksema. Holslag vof acted as co-developer bringing in knowledge on user-interfaces, flexibility of data-gathering and on presentation of data. The production of the tool was a joint venture between Holslag vof and Hermus Beeldbewerking. An extended update of the tool has been delivered in april 2004.

| OBKCOMP is a Benchmark & Dissemination project commissioned by the HBO-Raad. All 14 Dutch Academies for Art & Design were involved in a proces of talking and studying about ICT in art education (COMPuters and COMPetence). A network of 150 people, varying from teachers, managers, students and others involved came together in several paneldiscussions (all over the Netherlands), expertmeetings and a general seminar (in Eindhoven). The project did not focus on technical aspects of hard- and software but on the use of ICT as educational and/or education-assisting tool. Targets were the development of a stable network of professionals, the dissemination of best practises and recommandations for the future role of ict in art education. Especially on the use of portfolios, digital didactics, life long learning, etc. The projectwebsite still functions as a means of interaction and sharing of knowledge. There is a printed publication with a brief overview of projectresults (only available in Dutch). |

Graphical User Interface for a new ticket vending machine (TVM) for Dutch Railways. The designprocess was carried out in close cooperation with Leonard Verhoef (Human Efficiency bv,Utrecht) and Peter Hermus (Rotterdam). The new design is based on touch screen operation. The new average ordering time for tickets is faster than the fastest ordering time on the existing TVM. The changes on making mistakes in the ordering process have also been extremely lowered. Therefore a series of simulators with various design assumptions were built and tested by NS/R on different target groups (students, elderly people, etc). There are at this moment six of these socalled mini-TVM's in public use in the Amsterdam Central station. Later in 2001 Dutch Railways installed 600 new TVM's all over the Netherlands. The TVM has been so succesfull that the interface was extended in 2003 with various products like seasontickets, international tickets, etc. The extension of the TVM was carried out by the internal NS Design Department. In complex parts of the interface using new design specifications delivered by Holslag vof.

The weekly magazine 'Nederlands Tijdschrift voor Geneeskunde' was founded in 1857. In 1996 the publisher started the development of a database in which all volumes of the magazine (over 140 years) are digitally available. A variety of formats among which scans of printed pages (first 110 years), wordprocessortextfiles (70's) and complete page-layouts (from the 90's) were incorporated in one database accessable via directlink with the server (Microformat bv/Lisse) and partly via internet. At this moment various publishing-products are derived out of the database. Among many partners involved in the project 'Holslag vof' was asked to design the graphical userinterface and to develope typographic rules for transforming the detailed magazine lay-out to the screen. In magazinedesign a lot of the typographic variables are aimed at preserving space. Blockset type, multiple colums, small typesizes, etc. On the screen space is limitless but readability is a great concern. From this startingpoint rules were set and these were programmed (by Technodesign/Zoetermeer)into a special conversionmodule. After several testruns and adjustments to the rules this program is now capable of doing automatic transformation of the final printlay-outs into screenreadable type. Also some 45.000 articles from backissues could be converted easily by Technodesign via this way.

Seven Dutch companies from the kitchen and electronics branches have
combined forces in developing a vision on sustainable comfort. The Eco
Kitchen is the tangible and visible result, in which user convenience
and energy consumption have been improved considerably. Holslag vof was asked to design and produce the overallproject- cd/rom and -website (in cooperation with "Hermus Beeldbewerking" and with involvement of various other subcontractors). This was a complex task because of the great number of parties involved in the 'Kijk op Keukens' project. There were 16 primary information suppliers, among which a broad range from equipmentproducers to design companies and eco-consultanties. Each of these with different aims and different 'formats of results'. The gathering of projectresults and also the editorial process of synchronising these results to a coherent and clearly arranged database of information was a major task. The design of the userinterface was based upon three principles; visual clarity, horizontal connections of diverse info as an alternative to the common mineshaft-interaction and emphasizing important results via typographic means, but also via extra attentionlinks.

| As part of a corporate identity and a range of technical productbrochures a set of graphical elements was developed to represent the maximum lay-out of a given product. The product is an electronic keycardsystem with database facilities like time registration, entrance and exittimes, etc. Shown here above are KP3200 and KP3700.
