Objectives

Is a Component-based approach feasible for the development of UIs for embedded systems?

Initiate advances with regard to UI qualities (easy-to-use, functional, consistent, appealing) by transferring knowledge of the general HCI domain to embedded systems.

Deliverable 4.2: Component-based UI development, results after first case

Methodology

Research Component-based technologies HCI, especially on the level of methodology

Take into account regulations regarding ergonomics

Design and implement a component-based UI for (a subset of) the commonly selected case

Progress and Results (1)

Research: Component-based technologies for UI Continuing on Deliverable 4.1: Evaluation of existing UI

realization systems. During the orientation phase: Windows CE and Java versions Now: more focussed because Java platform has been chosen JavaBeans Investigate relation with SEESCOA component definition

Progress: major part of research has been done, deliverable is being written

Progress and Results (2)

Research: HCI, especially on the level of methodology Design guidelines for embedded systems (ES)

Found for ES as such or translated from general HCI HCI development methodology: ‘Contextual Design’

Investigate what can be transferred to ES developmentA representative example of participative developmentHas been emphasized more than foreseen, based on company visits during project orientation

UI notation and UI modellingGenerally not UMLUIDL from literature not suitableNeeded for communication with component systemLooking at XML (soon to be discussed with partners)

Practical work : Design and implementation Experience with technologies

Java versions for embedded systemsJavaBeans (component technology)

Setting up development platform for ES Starting up development of the case (currently)

In the context of the camera-based surveillance systemPreliminary design for UI for the caseTry to use preliminary version of component system (WP3)UI on development platform ES (local UI)UI on Palm PDA (e.g. remote UI, restricted possibilities, no standard component technology such as JavaBeans on Palm)

Diverse UIs with consistent look-and-feelTo be continued during next months

Conclusion

Progress research as foreseen in workplan

Despite the availability of somewhat less man-power than foreseen, only minor changes in topics on which has been focussed

Preliminary version of case is likely to be ready when task finishes, in 3 months

No changes in planning for next task, 4.3,Generalization of component-based UI.
