3D Food printer

The project aims to build a 3D food printer that is user-friendly for household users, through remodelling of the TEVO Tarantula 3D printer. Upon completion on configuration of hardware and software, an extrusion system is designed based on a meat mincer. The goal of this project is to print the customised dish with food material in high precisity. Another focus of this project is exploring food material applicable for 3D printing. With rich nutrient content and high formability, potatoes is chosen to make a great show with other supporting actress. The effort paid by the team does make an exciting return. It is wished that the efficiency of the printer can be greatly enhanced in the foreseeable future and finally be a necessary for a home.

Advancing optical label-free cellular imaging – from instrumentation to cell assays

Quantitative phase imaging (QPI) is an advanced optical microscopy technique that requires no sample staining and allows quantitative measurement of biophysical parameters of the cell specimens. This technique is desirable especially in live-cell imaging, as it can yield cellular dry mass distribution, intracellular dynamics as well as size of cells with minimal intervention/damage to the sample. A compact and easily-compatible setup of QPI was developed and applied to a wide range of biomedical applications, ranging from fundamental biological studies in brain imaging, to the clinical studies in drug-screening for breast cancer cells and characterization of pathogenic bacteria biofilms.

Realistic visualization of bridge structure in a Virtual Reality environment

Efficient collaboration of data is essential for successful project delivery of
Building Information Modeling (BIM), which mainly relies on its visualization performance. VR technology can extend the advantage to create a more engaging and realistic environment for every stakeholder. As a large number of software for BIM and VR computing are available on the internet, it is vital to find the most effective workflow to transfer the project from modeling tool to the VR engine.
In this project, we would explore the performance of different software and hardware to find the best solution to BIM-VR collaboration workflow.

Single cell traction force measurement assay with multiphoton-based protein micropatterns

A multiphoton-based protein micropatterning technique was developed in our lab previously. In this project, protein micropillar arrays were fabricated for cell seeding, and it was utilized for single cell traction force measurement. On the other hand, a method for encapsulating cells in collagen gel for cell therapy was also developed in the lab before. In order to improve the efficiency of cell therapy using this method, characteristics of these cells has to be identified. Therefore, the traction force of stem cells that are migrated out from the gel and the cells that are not encapsulated in the gel were measured and compared to understand the differences between them.

Identifying priority areas for the improvement of minibus service quality

The minibus is the third most popular form of transportation in Hong Kong, contributing 13% of all trips made in the city. This project aims to identify the priority areas for improvement of minibus services quality which could serve as a reference for related policy making in the future. An on-street questionnaire survey was conducted in December 2018 to collect the up-to-date data, primarily on the public’s ratings on 10 selected service aspects. An ordered logit model was then calibrated for the data to identify the relative importance of these 10 service aspects. After having the relative importance and the satisfaction ratings, an importance-satisfaction analysis was carried out to find out which service aspect has the highest priority for improvement. Result shows that among the 10 service aspects, “in-vehicle comfort” has the highest priority for improvement in both green and red minibuses.

The Library: A stealth game

The Library is a horror/stealth game with an interesting narrative and immersive 3D Graphics. It is set in a library scene with several obstacles which the player must dodge while being chased by a monster. The player is exposed to three power ups through the course of the game- restore sanity, Speed gain and invisibility which aid help him/her in his escape. The goal of the game is to obtain 4 out of the 7 hidden keys and finally escape from the clutches of the monster through the exit door without losing his sanity. The game was developed using the Unity Game Engine and captures the lenses of surprise, fun and curiosity.

Bookbytes

Bookbytes serves as an online social networking platform for both avid book readers and causal book readers. Users can maintain a list of books to read,already read, dropped and on hold. The defining feature is the availability of a multitude of book clubs catering to people of all ages of all tastes from all parts of the world, except maybe Antarctica. Users can also give and receive book recommendations, post on threads in the clubs they are in and also post comments in the thread. In essence, Bookbytes is a dedicated platform where book lovers can explore their ‘niche’ to their hearts’ content.Currently, only a free-app version with ad revenue pricing model is under consideration.

Club Grenade

Club Grenade is a fast-paced multiplayer action game which a group of friends and family of all ages, at a maximum of four players, can enjoy. In the game, each player controls a character who infiltrates a high-tech facility and fights through waves of enemies with grenades only. The game has a cartoony art-style with cel shading and outline. The game currently features four unique playable characters, four types of enemies, five types of grenades and a single large level with three stages, all fully animated and textured. The players win if they defeat all enemies and exit the level, or lose if all players have been defeated.
