In order to incorporate naturalness in the design of Human Computer Interfaces (HCI), it is desirable to develop recognition techniques capable of handling continuous natural gesture and speech inputs. Hidden Markov Models (HMMs) provide a good framework for continuous gesture recognition and also for multimodal fusion [11]. Many different researchers [13,(More)
Herein, we demonstrated a green approach for the synthesis of high surface area (850 m2 g-1) mesoporous perforated graphene (PG) from Bougainvillea flower for the first time using a template free single-step method. The existence of PG was confirmed by XRD, Raman spectroscopy, FESEM, and FETEM. Surprisingly, FETEM clearly showed 5-10 nm perforation on the(More)
Although computer technology has dramatically changed in the last 20 years, human-computer interfaces have largely remained unchanged. The keyboard has been the most prevalent device, but with the advent of graphical operating systems, the mouse has been added. To create a more natural and human-centric computer interface we propose using input modalities(More)
The synthesis of orthorhombic nitrogen-doped niobium oxide (Nb2O5-xNx) nanostructures was performed and a photocatalytic study carried out in their use in the conversion of toxic H2S and water into hydrogen under UV-Visible light. Nanostructured orthorhombic Nb2O5-xNx was synthesized by a simple solid-state combustion reaction (SSCR). The nanostructural(More)
In this report, CdS nanoparticles have been grown on the surface of CdWO4 nanorods via an in-situ approach and their high photocatalytic ability toward dye degradation and H2 evolution from H2S splitting under visible light has been demonstrated. The structural and optical properties as well as morphologies with varying amount of CdS to form CdS@CdWO4 have(More)
