BeyondTouch: A framework for extending input on commodity smartphones
نویسنده
چکیده
The primary mode of interaction with a smartphone is limited to the front-facing touchscreen and several physical buttons along the sides. This project will extend the input modality of a smartphone with built-in sensors (microphone, gyroscope, and accelerometer etc.). We will firstly introduce the prototype BackTap, adding four distinct tap locations on the back case of a smartphone. The BackTap interaction can be used eyes-free with the phone in a user’s pocket, purse, or armband while walking, or holding the phone with two hands. We also present evaluation data that showed users were able to tap four distinct points with 92% to 96% accuracy. Finally, we describe future research plans.

A Survey on Thai Input Methods on Smartphones
Smartphones have become vital devices in the current onthe-go Thai culture. Typically, virtual keyboards serve as tools for text input on smartphones. Due to the limited screen area and the large number of Thai characters, the size of each button on the keyboard is quite small. This leads to character mistyping and low typing speed. In this paper, we present a typical framework of a Thai Input ...

متن کاملPalmTouch: Using the Palm as an Additional Input Modality on Commodity Smartphones
Touchscreens are the most successful input method for smartphones. Despite their flexibility, touch input is limited to the location of taps and gestures. We present PalmTouch, an additional input modality that differentiates between touches of fingers and the palm. Touching the display with the palm can be a natural gesture since moving the thumb towards the device’s top edge implicitly places...
متن کاملCommodity price uncertainty propagation in open-pit mine production planning by Latin hypercube sampling method
Production planning of an open-pit mine is a procedure during which the rock blocks are assigned to different production periods in a way that leads to the highest net present value (NPV) subject to some operational and technical constraints. This process becomes much more complicated by incorporation of the uncertainty existing in the input parameters. The commodity price uncertainty is among ...

In knowledge-based economy, knowledge has a public good and non-rivalry nature. Firms build their own knowledge stock not only by means of internal R&D and collaboration with partners, but also by means of previously spilled over knowledge of other firms and public research laboratories (such as universities). Firms based on their absorptive capacity, and level of intra-industry and extra-indus...
