Calibration Approach

Colorimetric calibration computes the necessary color space transformation to map a camera's device-specific color space to a device-independent perceptual color space. Color calibration is most commonly performed by imaging a color rendition chart with a fixed number of color patches with known colorimetric values (e. g., CIE XYZ values). The color space transformation is estimated based on the correspondences between the camera's image and the chart's colors. We present a new approach to colorimetric calibration that does not require explicit color correspondences. Our approach computes a color space transformation by aligning the color distributions of the captured image to the known distribution of a calibration chart containing thousands of colors. We show that a histogram-based colorimetric calibration approach provides results that are onpar with the traditional patch-based method without the need to establish correspondences.

Cosmetic Problem

Heuristic evaluation merupakan salah satu bentuk usability testing perangkat lunak yang dinilai oleh pengguna (evaluator). Dalam melakukan heuristic evaluation instrumen penilaian terdiri dari sepuluh (10) pernyataan dengan lima pilihan jawaban dalam skala severity ratings. Dalam penelitian ini heuristic evaluation terhadap aplikasi Depo Auto 2000 Tanjung Api-Api Palembang yang dilakukan oleh 4 evaluator.  Hasil dari heuristic evaluation dikelompokkan kedalam  masing-masing instrumen yaitu visibility of system status dengan nilai 0,75, match between system and the real world dengan nilai 0,25, user control and freedom dengan nilai 0,25, consistency and standards dengan nilai 0,75, error prevention dengan nilai 1, recognition rather than recall dengan nilai 1,25, flexibility and efficiency of use dengan nilai 0,25, Aesthetic and minimalist design dengan nilai 0,25, help users recognize, diagnose, and recover from errors dengan nilai 1 dan Help and documentation dengan nilai 0. Dari hasil heuristic evaluation yang dilakukan menunjukkan bahwa evaluator memberikan nilai 0 dan 1 aplikasi Depo Atuo 2000 Tanjung Api-Api Palembang. Hasil penilaian tersebut menunjukkan bahwa aplikasi yang buat tidak ada masalah usability dan hanya memiliki cosmetic problem sehingga aplikasi Depo Auto 2000 Tanjung Api Api Palembang  dapat dinyatakan layak untuk didistribusikan kepada pengguna akhir (end user).

The Impact

To improve the construction industry’s capacity to deliver sustainable infrastructure, guidance on delivering green building systems needs to be more usable. Green buildings have certifications and ratings in place that ensure that projects are environmentally responsible and meet standards in resource efficiency. EarthCraft Multifamily (ECMF), an evolving green building certification, has been successful in increasing the delivery of energy-efficient affordable housing, and this study leverages user experience (UX) methodologies to understand how to further improve ECMF and replicate its success. This study identifies the impact ECMF tools and resources, such as the program manual, worksheet, and technical guidelines, have on enhancing project delivery for architects. This study conducted data analysis on project specifications, heuristic evaluation data, and stakeholder interview data. As the strengths and weaknesses of ECMF were identified, knowledge on the usability of the green building certification program was unveiled. Heuristic evaluations data show that accessibility and usability issues are present in ECMF resources. Interview data show that architects’ experiences with ECMF resources were affected by some of the usability issues identified in the heuristic evaluation data. Coded interview transcripts show the most prominent participant-identified improvements represented within the data. Resources need appropriate visual representation such as readability and hierarchy to improve their usability. Understanding how ECMF resources are utilized during project delivery allows for the appropriate content and options to be strategically framed to improve accessibility and enhance user decision making. ECMF resources can allow for the inclusion of a broader set of stakeholders by lowering the level of expertise required for sustainable infrastructure delivery.
