Project Soli: control electronic devices without physical contact

"Google has unveiled an interaction sensor that uses radar to translate subtle hand movements into gesture controls for electronic devices, with the potential to transform the way they're designed (+ movie).

Project Soli was one of the developments revealed by Google's Advanced Technology and Progress (ATAP) group during the company's I/O developer conference in San Francisco last week. The team has created a tiny sensor that fits onto a chip. The sensor is able to track sub-millimetre hand gestures at high speed and accuracy with radar, and use them to control electronic devices without physical contact."

Creating a Technical Specification

"A technical specification is a document that defines a set of requirements that a product or assembly must meet or exceed. A product or assembly that does not meet all of the specifically expressed requirements does not meet the specification, and often is referred to as being out of specification or 'out of spec.' Specifications are used when a contract for technical products or services is issued. The technical specification defines the requirements to fulfill the contract."

Complex representations not simple quantified measurement

"Primarily because of its association with achievements in the physical sciences, quantified measurement seems a step toward enhanced precision. But, precision, as understood here, means more than reliability and validity; it also requires appropriately complex representation of the target construct. In phenomenological terms, precision refers to the distinctiveness that fosters reliability, the coherence that assures validity, and the richness that is appropriate to the targeted phenomenon. First, distinctiveness is the extent to which a phenomenon is discriminable from others. Judgments about distinctiveness require more than explicit (e.g., operational) definitions. They require the capacity to anticipate attributes that remain implicit in even the most explicitly conceived phenomenon and, on the basis of those implicit meanings, to consistently verify that phenomenon's presence or absence. Second, coherence is the extent to which judgments about the attribute structure of a particular phenomenon are congruent. Short of logical entailment but beyond associative contingency, judgments about coherence require consideration of both the explicit and implicit meanings of the attribute structure they describe. Third, richness is the extent to which judgments about a phenomenon capture its complexity and intricacy. Richness entails full differentiation of a phenomenon's attributes, identification of its attribute structure, and appreciation of its structural incongruities."

[4] profiles and the ideal prototype. This numeric assessment of degree involves profiles of attributes rather than individual attributes. Although we appreciate the potential importance of the latter (see note 3), we have not attempted to address the analytic problems that arise from the combination of nominal and ordinal variables in estimates of profile similarity. It should be noted, however, that some available software facilitates the assessment of ordinal information during attribute identification (cf. KUCKARTZ 1995; WEITZMAN & MILES 1995). The possibility of coordinating ordinal and nominal attribute judgments deserves further consideration.
