- In the digitalized era, we do less and less physical work, which in turn leads to less physical activities. Many different wearables and applications try to motivate us to exercise more but people stop using them after a couple of months. One of the reasons people stop using them is because they serve as a post-activity viewing and not as a motivator. Meanwhile, the gaming industry has spent years of perfecting the art of creating addictive games. One idea is to utilize other technology such as virtual reality (VR) to encourage people to exercise more. VR is a computer-generated world, which tracks users and can give users an illusion of participating in a synthetic environment. This paper aims to introduce a Fitness VR application, which was developed and evaluated. The application contains three exercises and a mindfulness scene, the evaluation focus on how different gamification and interaction techniques can be used to motivate users to exercise more. Initial findings show that the participants find the Fitness VR application fun and motivating.

- We investigate the surface-enhanced Raman scattering (SERS) of rhodamine 6G (R6G) adsorbed on Au nanoparticles attached to InP nanowires. We find that nanowire arrays act as frameworks for effective SERS substrates with a significantly higher Raman signal sensitivity than a planar framework of Au nanoparticles adsorbed two-dimensionally on a flat surface. The SERS signal displays a clear polarization-dependent effect when the nanowires are arranged in a row. We also find that the SERS signal increases with time during continuous laser illumination. The plasmon-enhanced optical forces between Au nanoparticles may either move pairs of nanoparticles closer together or attract adsorbed molecules by moving them to the junctions of Au nanoparticle aggregates. Such effects by plasmon optical forces may cause the observed increase of the SERS signal with continuous laser illumination.

Failure of the vapor-liquid-solid mechanism in Au-assisted MOVPE growth of InAs nanowires
- 2005

- We report the temperature dependence of the Au-assisted growth of InAs nanowires in MOVPE. Extensive studies of the growth of such nanowires have attributed growth to the so-called vapor-liquid-solid (VLS) mechanism, with a liquid Au-In alloy particle. We assert here that growth is instead assisted by a solid particle and does not occur at all when the particle is a liquid. Thus the temperature range of InAs nanowire growth is limited by the melting of the Au-In alloy. Comparison with growth of InAs nanowires in the same system assisted by a layer of SiOx is used to support this conclusion.
