2021-2022 : SmartBreed : Grâce à des boîtes de sélection automatisées, les agriculteurs peuvent élever des sauterelles dans leurs fermes. Ceux-ci convertissent les sous-produits agricoles en protéines de poulets, améliorant ainsi leur santé et contribuant à une production régionale circulaire résiliente. Les box d'élevage ont été nettement améliorés en termes de matériel, de volume d'élevage et de fonctionnalité. Les coûts de fabrication étaient principalement dus aux raisons suivantes : Les augmentations massives des prix des matières premières ne sont pas descendues en dessous de 750 francs, mais grâce à de nouveaux partenaires industriels, ils ont été maintenus au niveau d'avant les augmentations de prix. A partir des retours clients de 31 box d'élevage, des optimisations ont été mises en place, notamment au niveau de l'élimination des insectes et de la robustesse des box. Grâce à la reconnaissance d'images et à l'intégration dans l'infrastructure informatique, les images dans le box d'élevage peuvent être évaluées automatiquement et en réalité. La taille des insectes, la quantité de nourriture et le mouvement du tapis roulant sont vérifiés et transmis. Le système fonctionne de manière stable et le taux de défaillance a été réduit de 13 % à moins de 5 %. Les clients peuvent voir toutes les informations essentielles en un coup d’œil sur un nouvel écran.

2019-2020: In the Erleb-AR project financed by the Swiss Federal Office of Culture an outdoor augmented reality application is developed to visualize 4 cultural heritage sites in Switzerland. The project is called Erleb-AR, because it is supposed to make the cultural heritage practically tangible with augmented reality. The title Erleb-AR is word play with the German adjective “erlebbar” which means in German experienceable and AR.
In the project an app for mobile devices is developed that allows the outdoor AR visualization of historical buildings that don’t exist anymore. To illustrate the project idea, a concept video was created: https://youtu.be/zdezcX9PfRs. As an example of the concept video we chose the 1834 demolished Christoffelturm on the Berne main station. All those who have installed our app on their mobile device can experience this imposing tower again.

2018-2019: In the ID-Verification (CTI-Nr. 28304.1PFES-ES) 2017-19: Smartphone based software solution for the user verification and the detection of security elements of ID documents.

2017-18: In the ADPS - Alzheimer Disease Prediction Service (KTI 18996.2 PFLS-LS) project, a mobile application is being developed in which information for a non-invasive diagnosis of Alzheimer's is collected using an augmented reality game and the movement sensor data. The game will be played by patients with a risk of Alzheimer Disease. Current state-of-the-art diagnostic measures of Alzheimer's disease (AD) are invasive (cerebrospinal fluid analysis), expensive (neuroimaging) and time-consuming (neuropsychological assessment) and thus have limited accessibility as frontline screening and diagnostic tools for AD. This project proposes a novel computational biomaker for mobile phones (ADPS) which may facilitate early and potentially more effective therapeutic and preventative strategies for AD.

2016-2017: In the Bodygee3D project (CTI 19154.2 PFES-ES), a morphable body model is created using 3D body scans to use 3D body scans in the areas of nutritional advice and fitness. The aim of this project is the development of an analysis module that determines the effectiveness of the habit change/training on the specific body parts based on 3D body scans and enables predictions of body changes using a morphable body model. Obesity is becoming a widespread disease. Only those who permanently change their habits have good chances of reaching and maintaining lower body weight. This project enables not only statements that body fat has been reduced to be made but with much greater accuracy where fat has been lost. In this way, the weight-loss behavior and the effectiveness of the training/behavior change can be documented. In the medium term, the goal is to be able to make additional statements about the relationship between muscle, fat and water content in relation to the individual body parts and by using local impedance measurements. However, this is not part of this project. With the Body Morphable Model, not only can states be recorded, but thanks to the parameterization and the statistically determined data, the course (first legs, then buttocks ...) of the change in body shape can be simulated in the medium term.

2015-2016: In the CleverScan project (KTI 15620-1 PFES-ES), a camera system was developed with which manholes can be scanned and measured in 2D and 3D. The system will go into production in 2016. The new camera produces a detailed 3D-reconstruction of the manhole with detailed images mapped on the 3D surface. The camera uses five sensors: Fore synchronized sensors to the side are used for the scanning and one sensor downwards captures a full HD video stream. The 3D-reconstruction is done using 4 plane lasers.

2014-2015: In the i-Lumica Expert Gate project (KTI 14281-1 PFES-ES), a system consisting of 40 cameras and 20 beamers was developed with which Ha-gel cells can be detected on car bodies. The application realizes several modules to accomplish these tasks. A data acquisition module retrieves 2D and 3D data from the surface scanning hardware provided by i-Lumica AG. Depending on the current analysis run, the 3D data part is cleaned, repaired and optimized to produce mesh data of cars which act as virtual master models. A segmentation module is used to identify, segment and store car body parts based on these master models. Finally, a surface analysis module uses the acquired 2D hail damage data of an ad-hoc car body to simulate hail and assess damaged parts based on the master model of the same car type.
The information gained from such a damage analysis is stored in enhanced databases for further analysis and online access as well as online visualization for 3rd party service providers like insurance companies, logistics experts and engineers.

2012-2014: In the Multimodal Passenger Flow Control System (KTI 13316.1 PFFLE-IW) project, intelligent stereo cameras were developed with which the flow of people in large buildings can be monitored. The camera system was successfully launched on the market.

2015-2017: Virtual Room VR: The Virtual Room project is about allowing several people to meet in a virtual room via the network. Each person wears newer generation VR glasses (e.g. HTC Vive or Oculus Rift) with two hand controllers each, the position and orientation of which are precisely recorded in the respective real room and synchronized via the network. It is possible for a person in Switzerland and a person in Australia to meet in a virtual space and not only communicate verbally and visually, but also interact manually with their hands. Together you can e.g. look at a model of a machine and agree on a possible repair. The respective representation of one's own body in virtual space can be chosen freely. The video below shows a demonstration of the project at the BFH stand at the 2016 professional fair in Bern.
