Hand-Eye Calibration without Hand Orientation Measurement Using Minimal Solution

In this paper we solve the problem of estimating the relative pose between a robot’s gripper and a camera mounted rigidly on the gripper in situations where the rotation of the gripper w.r.t. the robot global coordinate system is not known. It is a variation of the so called hand-eye calibration problem. We formulate it as a problem of seven equations in seven unknowns and solve it using the Gr...

Hand Tracking via Efficient Database Indexing

Tracking the pose of a moving hand from a monocular perspective is a difficult problem. In the current study the tracking problem is recast as efficient database indexing. Recognition is hastened by approximating chamfer distances between hand poses which have been embedded into a common vector space. Using this embedding, a small number of candidate matches for each query can be quickly identi...

Reliability of the Modified In-hand Manipulation Test and the Relationship Between In-hand Manipulation and Handwriting

Objectives: This study aimed at analyzing the test-retest and interrater reliabilities of the Test of In-Hand Manipulation-Modified (TIHM-M), as well as the relationship between in-hand manipulation and handwriting. Methods: We administered the TIHM-M twice, two days apart, and the Beknopte Beoordelingsmethode voor Kinder Handschriften (BHK) - Concise Assessment Method for children’s handwriti...

Comparing Dominant and Non-Dominant Hand Performance with Force Changes In a Two-Hand Equilibrium Task: A Challenge to Dominant Hand Theories

Objective: Although most studies believe that the dominant hand performs better than the non-dominant hand in performing various tasks, there is still the challenge among researchers as to why the non-dominant hand performs better than the dominant hand in certain situations and tasks. The aim of this study was to compare dominant and non-dominant hand performance with force changes in a two-ha...
