ABSTRACT
This paper presents a low-cost and practical approach to achieve basic input using a tactile cube-shaped object, augmented with a set of sensors, processor, batteries and wireless communication. The algorithm we propose combines a finite state machine model incorporating prior knowledge about the symmetrical structure of the cube, with maximum likelihood estimation using multivariate Gaussians. The claim that the presented solution is cheap, fast and requires few resources, is demonstrated by implementation in a small-sized, microcontroller-driven hardware configuration with inexpensive sensors. We conclude with a few prototyped applications that aim at characterizing how the familiar and elementary shape of the cube allows it to be used as an interaction device.

Expectation‐maximisation‐based localisation using anchors with uncertainties in wireless sensor networks
Localisation in wireless sensor networks (WSNs) has received much attention, where most studies focus on mitigating the effects of measurement noise under the assumption of accurate anchors’ positions. However, anchors’ positions could be inaccurate for ...
Passive Multipath Time Delay Estimation Using MCMC Methods
Passive time delay estimation in multipath environments is studied in this paper. A novel restrained maximum likelihood (ML) estimator is proposed to estimate the multiple time delays. Unlike traditional ML function which has P global maximum values, ...
Maximum Likelihood Direction Finding in Spatially Colored Noise Fields Using Sparse Sensor Arrays
We consider the problem of maximum likelihood (ML) direction-of-arrival (DOA) estimation of narrowband signals using sparse sensor arrays, which consist of widely separated subarrays such that the unknown spatially colored noise field is uncorrelated ...
