Emerging technology on mobile and wearable market, smartwatches have embedded movement sensors whose potential is yet to be fully explored. This paper proposes an interaction method with smart TVs via gestures performed by person's wrist using a smartwatch. Detailed architecture implementation for complete prototype, named Wrist Player, presented. A user study also conducted, in order evaluate the prototype performance user's interest proposal. Results show that works very well, participants...
Nowadays, due to touchscreen, mobile devices have become much more dynamic than in the past. However, same reason, those are less accessible for blind people. It is expected that 2018, over half of phone users will a smartphone, therefore researches about accessibility very important. So, aim this systematic review cooperate with new research methods braille text entry on smartphones. The searches 5 databases, resulted 11 papers answered questions grounded work.
This work proposes the development of a method for smartwatches that allows to control platform games using continuous recognition gestures and conducts case study as game Super Mario World. Uses set based on geometric shapes send actions game. Gesture is performed by algorithm gesture recognition, it able recognize before being finalized, an action be quickly, improving feedback. The process was paralleled improve performance. A technique has been developed execution several in sequence,...
Smartwatches are gaining popularity on market with a set of features comparable to smartphones in wearable device. This novice technology brings new interaction paradigms and challenges for blind users, who have difficulties dealing touchscreens. Among variety tasks that must be studied, text entry is analyzed, considering current existing solutions may unsatisfactory (as voice input) or even unfeasible working tiny QWERTY keyboards) user. More specifically, this paper presents study...
